Surface Meteorology Data: (NCDC) (FIFE)

Summary:

The NOAA Regional Surface Data - 1989 (NCDC) Data Set contains hourly surface meteorological data for the FIFE area. Though the measurements presented in this data set were not taken precisely at the FIFE study area, it is hypothesized that they present a representative horizontal cross-section of meteorological variables and sky conditions in and around the site. It is also realized that many of the variables presented in this data set are somewhat subjective and dependent on the skill (and biases) of the observer, such as estimates of cloud amount and height. This data may be used as input data and/or verification data for numerical simulation models.

1. Data Set Overview:

Data Set Identification:

Surface Meteorology Data: NCDC (FIFE)
(NOAA Regional Surface Data - 1989 (NCDC)).

Data Set Introduction:

The NOAA Regional Surface Data - 1989 (NCDC) Data Set documented within this report are hourly surface meteorological data from selected stations centered around the FIFE study area. This data set contains hourly surface meteorological data for the FIFE area.

Objective/Purpose:

The FIFE Staff Science effort covered those activities which were FIFE community level activities, or required uniform data collection procedures across sites and time. These activities included the acquisition, processing and archiving of meteorological parameters of the atmosphere. This data set contains hourly surface meteorological data for the FIFE area. This data may be used as input data and/or verification data for numerical simulation models.

Summary of Parameters:

  1. Meteorological parameters : sea level pressure, dew point temperature, wind direction, wind speed, surface pressure, dry bulb temperature, wet bulb temperature, relative humidity;
  2. Weather parameters : visibility, and present weather (contains precipitation variables)
  3. Cloud and sky parameters : sky conditions for four layers, total sky cover; and cloud type, height, and amount for four layers.

Discussion:

The NOAA regional surface data were extracted from the NOAA operational analysis system, and were archived at the National Climatic Data Center. The data set documented within this report are hourly surface meteorological data from selected stations centered around the FIFE study area.

The NOAA Regional Surface Data - 1989 (NCDC) were produced by the National Oceanic and Atmospheric Administration (NOAA) and archived by the National Climatic Data Center (NCDC).

3. Theory of Measurements:

Though the measurements presented in this data set were not taken precisely at the FIFE study area, it is hypothesized that they present a representative horizontal cross-section of meteorological variables and sky conditions in and around the site. It is also realized that many of the variables presented in this data set are somewhat subjective and dependent on the skill (and biases) of the observer, such as estimates of cloud amount and height.

4. Equipment:

Sensor/Instrument Description:

A variety of instruments are used in gathering the NOAA surface weather data. Standard instruments include anemometers, tipping bucket rain gauges, psychrometers, and aneroid pressure sensors, and wet and dry bulb thermometers. Description of specific instruments at each regional site are not available to FIS staff at this time. Questions pertaining to instrumentation may be addressed to the National Climatic Data Center.

Collection Environment:

Ground-based.

Source/Platform:

Instruments were mounted within and in the proximity of standard NOAA surface meteorological stations.

Source/Platform Mission Objectives:

To provide surface meteorology data from meteorological stations for the area surrounding the Konza Prairie.

Key Variables:

Standard meteorological variables (temperature, wind, pressure, and humidity), weather variables (weather and visibility) and cloud parameters (type, height, amount).

Principles of Operation:

8. Data Organization:

Data Granularity:

This data set contains point data acquired from October 1, 1988 through October 31, 1989. The data was collected in hourly time intervals.

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 begins 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_ID)). 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:

Not available at this revision.

Data Processing Sequence:

Processing Steps:

FIS staff obtained the initial data from the National Climatic Data Center in the form of 6250 bpi magnetic computer tapes. Data was read from the tapes and inserted into appropriate data columns. Much of the data in encoded, and users of this data set will have to use the Other Relevant Information Section to interpret these values. In addition, FIS staff filled missing values with the value of 9999.

Processing Changes:

NOAA identifies surface stations with WBAN surface station identification numbers. This number is different than the identification numbers that were used in the 1987-1988 data set (FIS identification numbers). FIS staff converted the WBAN numbers to corresponding FIS identification numbers. the Other Relevant Information Section contains documentation for both numbers. FIS staff inserted the value of 9999 where missing values were noted.

Calculations:

None performed by FIS staff.

Special Corrections/Adjustments:

None.

Calculated Variables:

None.

Graphs and Plots:

None.

10. Errors:

Sources of Error:

Most remote station problems are detected at the base by direct observation of data being received and displayed. Determining the nature of most problems is generally straightforward. Typical problems experienced in the field, which introduce errors in the data are :

Quality Assessment:

Data Validation by Source:

It is assumed that NOAA/NESDIS does a quality check of the data, before archiving and delivery to researchers. In addition, FIS staff performed preliminary data quality control, checking maximums and minimums in all data fields.

Confidence Level/Accuracy Judgment:

FIS staff believes this data to be of high quality.

Measurement Error for Parameters:

Not available at this revision.

Additional Quality Assessments:

Not available at this revision.

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:

Not available at this revision.

Usage Guidance:

Users of the data set will need to use the documentation contained in the Other Relevant Information Section to interpret the information contained in the data columns.

Any Other Relevant Information about the Study:

Not available at this revision.

12. Application of the Data Set:

This data may be used as input data and/or verification data for numerical simulation models.

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:

NOAA Regional Surface Data - 1989 (NCDC) are available on FIFE CD-ROM Volume 1. The CD-ROM filename is as follows:

\DATA\SUR_MET\NCDC_SUR\GRIDxxxx\YyyMmm\ydddgrid.NCS

Where xxxx is the four digit code for the location within the FIFE site grid, yy is the last two digits of the year (e.g., Y87 = 1987) and mm is the month of the year (e.g., M12 = December). 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 (e.g., 061 = sixty-first 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 .NCS for this data set.
