Daily Rainfall Data (FIFE)

Summary:

The FIFE Daily Rainfall Data Set contains daily precipitation values for 42 rain gauge stations within the Konza LTER portion of the FIFE site (i.e., Northwest quadrant). The data set is a composite of data collected by the LTER staff and the Princeton University group.

The LTER staff collected daily precipitation data from 12 of the 42 rain gauge stations within this area with the Princeton University group collecting 30 minute precipitation data from the remaining 30 stations. LTER data was collected from April 1982 through December 1989. Data collected by the LTER staff was year round for some stations and from April 1 to October 31 for others. The Princeton University group collected data from May 1987 to October 1987. The Princeton University 30 minute precipitation data was converted to daily precipitation data by the FIS staff. At any particular time, data from approximately 20 of the 30 Princeton University stations were recovered. High temperatures and humidity, plus software problems in the rainfall data loggers, resulted in these data losses. The collected data were of high quality and enough gauges were working at all times so that rain cells could be observed using these data.

1. Data Set Overview:

Data Set Identification:

Daily Rainfall Data (FIFE).
(Daily Rainfall Amounts in the Konza Research Area).

Data Set Introduction:

The FIFE Daily Rainfall Data Set contains daily precipitation values for 42 rain gauge stations within the Konza LTER portion of the FIFE site (i.e., Northwest quadrant). The data set is a composite of data collected by the LTER staff and the Princeton University group.

Objective/Purpose:

The FIFE Staff Science efforts to collect precipitation data focused on quantifying the spatial variation of rainfall across the Long-Term Ecological Research site (LTER) portion of the FIFE site. The data collected by Princeton University in the Kings Creek catchment and subcatchments were focused on determining the major elements of the water balance of these catchments using catchment, water-budget models with a temporal resolution of 20 days.

Summary of Parameters:

Total daily rainfall.

Discussion:

This data set contains daily precipitation values for 42 rain gauge stations within the Konza LTER portion of the FIFE site (i.e., Northwest quadrant).

The LTER staff collected daily precipitation data from 12 of the 42 rain gauge stations within this area. LTER data was collected from April 1982 through December 1989. The number of LTER stations collecting data over this period varied from 1 in April 1982 to 11 in December 1989. Data collected by the LTER staff was year round for some stations and from April 1 to October 31 for others.

The Princeton University group collected 30 minute precipitation data from 30 of the 42 rain gauge stations within this area from May 1987 to October 1987. The Princeton University 30 minute precipitation data was converted to daily precipitation data by the FIS staff. At any particular time, data from approximately 20 of the 30 Princeton University stations were recovered. High temperatures and humidity, plus software problems in the rainfall data loggers, resulted in these data losses. The collected data were of high quality and enough gauges were working at all times so that rain cells could be observed using these data.

Requested Form of Acknowledgment.

The original rainfall daily amounts were collected by the staff of the civil engineering department at Princeton University, and Kansas State University. The assistance of John Briggs at the KSU LTER site in directing and preparing these data is particularly appreciated. The data from the Long-Term Ecological Research (LTER) site were collected under the Konza Prairie LTER grant BSR 8514327 funded by the National Science Foundation.

3. Theory of Measurements:

The LTER used weighing-type gauges in which a weighing mechanism converted the weight of the rainfall caught by a circular, horizontal opening at the top of the gauge into the curvilinear movement of a recording pen which made an inked trace on a rectangular paper chart. The height of the pen marks on the chart were calibrated to rainfall amount.

The University of Princeton used tipping bucket rain gauges in which a 0.2 mm tip connected to a data logger (that recorded the date and time to within 1 min of the tip) was used to record rainfall. The one minute rainfall readings were aggregated into 30 minute intervals, by the Princeton University group. The FIS staff calculated daily rainfall by aggregating the 30 minute rainfall values into daily total rainfall values based on Central Daylight Saving Time.

4. Equipment:

Sensor/Instrument Description:

The LTER rain gauge is describe in the sections below. For information on the instrumentation used by Princeton University see the Kings Creek Watershed 30 Minute Precipitation document. It describes the primary data set from which these daily data were computed.

Collection Environment:

Ground-based.

Source/Platform:

The LTER rain gauges were mounted on poles (that were centered on concrete pads) 3 feet above the ground.

Source/Platform Mission Objectives:

The objectives were three fold, 1) to provide baseline long-term monitoring data for the Konza Research area, 2) to quantify the spatial variation of rainfall across the FIFE site and, 3) to determine the major elements of the water balance of the Kings Creek catchment using catchment, water-budget models with a temporal resolution of 20 days.

Key Variables:

Daily rainfall depth at rain gauge locations.

Principles of Operation:

LTER

The charts, for the LTER rain gauges, (graduated in inches, or millimeters, of rainfall) were wrapped around a vertical cylinder which was rotated either by an 8-day spring-powered, or a long-term battery-powered, chart drive. In some gauges of this series the record capacity of the gauge was reached in a single traverse of the pen across the chart; in others it was reached after a double traverse of the pen. Charts were manually replaced each week, the buckets emptied and the timing mechanism for the drum rewound.

Weighing Mechanism. The rainfall falling through the 8"-diameter collector was caught in a bucket resting on a platform mounted to the vertical link of a 4-bar linkage. The vertical link, or movement bracket, was supported from the mechanism frame by a precision extension-spring assembly. The upper horizontal link, or top lever, of the linkage was provided with an adjustable extension by which the deflection of the spring was multiplied and modified to fit the requirements of the recording mechanism. A second horizontal link, or lower lever (ns), provided the additional constraint needed to keep the movement bracket vertical throughout its deflection. The top and lower levers turned in the mechanism frame; the movement bracket turned in the top and lower levers. A limit screw at the top rear of the mechanism prevented the recording pen from striking the chart cylinder flange when the catch bucket was removed from the gauge by limiting the upward movement of the top lever. A second limit screw, attached to the movement bracket, prevented the pen from falling off the top of the chart cylinder in single-traverse gauges and from striking the chart cylinder flange in dual-traverse gauges. The bottom of the movement bracket was linked to the piston of a damping device, a dashpot, to reduce pen arm vibrations due to wind gusts.

PRINCETON

For a description of the principles of operation for the instrumentation at the rain gauges operated by Princeton University, see the document describing the 30 minute rainfall data set (Kings Creek Watershed 30 Minute Precipitation) from Princeton University.

Sensor/Instrument Measurement Geometry:

The LTER rain gauges were permanently mounted on poles 3 feet above the ground. The poles were centered on concrete pads and the vegetation around the pads was kept low.

Manufacturer of Sensor/Instrument:

LTER Rain Gauge Manufacturer :

Belfort Instrument Company
1600 South Clinton Street
Baltimore, Maryland 21224

Calibration:

The instruments used by the LTER staff were purchased in a calibrated form and were re-calibrated each spring using weights of known mass.

See the Kings Creek Watershed 30 Minute Precipitation document for calibration information on the Princeton University data.

Specifications:

The LTER uses weights of known mass to perform the calibration.

Tolerance:

LTER rain gauges: 0.001 grams i.e., 1 mm

Frequency of Calibration:

LTER rain gauges are calibrated once per year.

Other Calibration Information:

LTER rain gauges are covered for the winter and taken out of service until spring (October 31 to April 1).

5. Data Acquisition Methods:

The LTER strip charts are removed from the rain gauges on a weekly basis and the highest daily rain value is manually read from these charts. These data are then manually entered into the data base on the LTER computer.

The University of Princeton rain data were acquired from Dr. Eric Wood and was derived from the thirty minute rainfall amounts for Kings Creek described in the Kings Creek Watershed 30 Minute Precipitation document.

8. Data Organization:

Data Granularity:

This is point data containing daily rainfall amounts based on local time.

A general description of data granularity as it applies to the IMS appears in the EOSDIS Glossary.

Data Format:

The CD-ROM file format consists of numerical and character fields of varying length separated by commas. The character fields are enclosed with a single apostrophe. There are no spaces between the fields. Each file begin with five header records. Header records contain the following information:

Record 1 Name of this file, its table name, number of records in this file, path and name of the document that describes the data in this file, and name of principal investigator for these data. Record 2 Path and filename of the previous data set, and path and filename of the next data set. (Path and filenames for files that contain another set of data taken at the same site on the same day.) Record 3 Path and filename of the previous site, and path and filename of the next site. (Path and filenames for files of the same data set taken on the same day for the previous and next sites, sequentially numbered by SITEGRID.) Record 4 Path and filename of the previous date, and path and filename of the next date. (Path and filenames for files of the same data set taken at the same site for the previous and next date.) Record 5 Column names for the data within the file, delimited by commas. Record 6 Data records begin.

Each field represents one of the attributes listed in the chart in the Data Characteristics Section and described in detail in the TDF file. These fields are in the same order as in the chart.

9. Data Manipulations:

Formulae:

Derivation Techniques and Algorithms:

The LTER data uses a simple conversion based on the weight to height of the pin markings on the drum strip chart to determine the amount of rainfall.

Data Processing Sequence:

Processing Steps:

The LTER rainfall data is read directly from the strip chart in millimeters of rainfall (conversions are made at the time of extraction from the chart). Only maximum daily values are read from the chart.

The Princeton University data was converted to daily total rainfall by the FIS staff. The daily totals were made using Central Daylight Saving time, not Greenwich Mean Time.

Processing Changes:

None.

Calculations:

None required for the LTER data.

Princeton University 30 minute rainfall values were converted to daily total rainfall values by aggregating all 30 minute rainfall values recorded during a day. This was done for each of the Princeton University sites. The daily total rainfall calculations were done using Central Daylight Saving Time, not Greenwich Mean Time.

Special Corrections/Adjustments:

None.

Calculated Variables:

Daily total rainfall values.

Graphs and Plots:

None.

10. Errors:

Sources of Error:

Occasionally the LTER mechanical chart recorders would fail to chart an entire week, usually because the clock was not wound sufficiently.

See the Kings Creek Watershed 30 Minute Precipitation document for sources of error for the Princeton University data.

Quality Assessment:

See the Kings Creek Watershed 30 Minute Precipitation document for quality assessment of the Princeton University data.

The LTER data points are routinely compared with that recorded by the rain gauge located on the Kansas State University campus.

Confidence Level/Accuracy Judgment:

The data from the LTER staff is good quality. The staff has a high level of confidence in its accuracy.

See the Kings Creek Watershed 30 Minute Precipitation document for details on the University of Princeton data.

Measurement Error for Parameters:

The LTER data has a measurement error of + or - 1 mm, which is equivalent to the width of the pen/ink on the strip chart.

Additional Quality Assessments:

FIS staff applied a general QA procedure to the data to identify inconsistencies and problems for potential users. As a general procedure, the FIS QA consisted of examining the maximum, minimum, average, and standard deviation for each numerical field in the data table. Inconsistencies and problems found in the QA check are described is the Known Problems with the Data Section.

Data Verification by Data Center:

The data verification performed by the ORNL DAAC deals with the quality of the data format, media, and readability. The ORNL DAAC does not make an assessment of the quality of the data itself except during the course of performing other QA procedures as described below.

The FIFE data were transferred to the ORNL DAAC via CD-ROM. These CD-ROMs are distributed by the ORNL DAAC unmodified as a set or in individual volumes, as requested. In addition, the DAAC has incorporated each of the 98 FIFE tabular datasets from the CD-ROMs into its online data holdings. Incorporation of these data involved the following steps:

Each distinct type of data (i.e. "data set" on the CD-ROM), is accompanied by a documentation file (i.e., .doc file) and a data format/structure definition file (i.e., .tdf file). The data format files on the CD-ROM are Oracle SQL commands (e.g., "create table") that can be used to set up a relational database table structure. This file provides column/variable names, character/numeric type, length, and format, and labels/comments. These SQL commands were converted to SAS code and were used to create SAS data sets and subsequently to input data files directly from the CD-ROM into a SAS dataset. During this process, file names and directory paths were captured and metadata was extracted to the extent possible electronically. No files were found to be corrupted or unreadable during the conversion process.

Additional Quality Assurance procedures were performed as follows:

As errors are discovered in the online tabular data by investigators, users, or DAAC staff, corrections are made in cooperation with the principal investigators. These corrections are then distributed to users. CD-ROM data are corrected when re-mastering occurs for replenishment of CD-ROM stock.

11. Notes:

Limitations of the Data:

Not available.

Known Problems with the Data:

The LTER sites may having periods in which no data was recorded due to insufficient winding of clocks.

See the Kings Creek Watershed 30 Minute Precipitation document for known problems with the Princeton University data.

Usage Guidance:

The LTER data only contains values of total rainfall for days in which rainfall was recorded.

The Princeton University data contains values of Total Rainfall on days in which no rainfall was recorded.

Any Other Relevant Information about the Study:

An analysis determined that 20 - 30 rain gauges should be able to estimate storm rainfall volume to within 10% with a reliability of 15%.

12. Application of the Data Set:

This data set can be used to quantify the spatial variation of rainfall across the FIFE site and to determine the major elements of the water balance of the Kings Creek catchment using catchment, water-budget models with a temporal resolution of 20 days.

13. Future Modifications and Plans:

The FIFE field campaigns were held in 1987 and 1989 and there are no plans for new data collection. Field work continues near the FIFE site at the Long-Term Ecological Research (LTER) Network Konza research site (i.e., LTER continues to monitor the site). The FIFE investigators are continuing to analyze and model the data from the field campaigns to produce new data products.

14. Software:

Software to access the data set is available on the all volumes of the FIFE CD-ROM set. For a detailed description of the available software see the Software Description Document.

16. Output Products and Availability:

Daily Rainfall Amounts in the Konza Research Area are available on FIFE CD-ROM Volume 1. The CD-ROM filename is as follows:

\DATA\SUR_MET\RAIN_DAY\Yyyyy\ydddgrid.RDY

Where xxxx is the four digit code for the location within the FIFE site grid, yyyy is the four digits of the century and year (e.g., Y1987 = 1987), and ddd is the day of the year, (e.g., 061 = sixty-first day in the year). Note: capital letters indicate fixed values that appear on the CD-ROM exactly as shown here, lower case indicates characters (values) that change for each path and file.

The format used for the filenames is: ydddgrid.sfx, where grid is the four-number code for the location within the FIFE site grid, y is the last digit of the year (e.g., 7 = 1987, and 9 = 1989), and ddd is the day of the year. The filename extension (.sfx), identifies the data set content for the file (see the Data Characteristics Section) and is equal to .RDY for this data set.
