NWS Daily Climatology Data: 1983 (SNF)

Summary:

Weather data were collected by the National Weather Service in International Falls, Minnesota. International Falls is about 80 miles from the SNF, but the weather data are representative of the area. Total solar insolation measurements were made at Fall Lake Dam in Winton, Minnesota, by Prof. Donald Baker of the Department of Soil Science at the University of Minnesota, St. Paul. Insolation values were measured using a Yellow Springs solar cell calibrated against an Eppley Pyranometer.

1. Data Set Overview:

Data Set Identification:

NWS Daily Climatology Data: 1983 (SNF).

Data Set Introduction:

Weather data were collected by the National Weather Service in International Falls, Minnesota. International Falls is about 80 miles from the SNF, but the weather data are representative of the area. Total solar insolation measurements were made at Fall Lake Dam in Winton, Minnesota, by Prof. Donald Baker of the Department of Soil Science at the University of Minnesota, St. Paul. Insolation values were measured using a Yellow Springs solar cell calibrated against an Eppley Pyranometer.

Objective/Purpose:

Not available.

Summary of Parameters:

Daily temperature (minimum, maximum, average), precipitation, insolation.

Discussion:

Daily weather data for the years 1972 through 1990 are stored in a collection of data sets with each data set containing one year's data, plus a data set including the entire data collection. The data set names are in the form:

Footnote:

For presentation in this document, some padding blanks may have been eliminated between columns in the Sample Data Record. Due to the many fields in this data file, these columns will wrap while viewing. The actual data files, however, are column delimited with an adequate record length to prevent wrapping. See the Data Format Section for conventions used for missing data values in the data file.

8. Data Organization:

Data are sorted by observation date (obs_datc) and location (location). Key fields in each record are location and obs_datc.

Data Granularity:

Each data set consists of a single ASCII file containing climatology data for each location for an entire year, except in the case of "NWS Daily Climatology Data: 1972-1990" which contains the climatology data for the entire period 1972-1990.

A general description of data granularity as it applies to the IMS appears in the http://daac.ornl.gov.

Data Center Status/Plans:

The Superior National Forest Data are available from the ORNL DAAC. Please contact the ORNL DAAC User Services Office for the most current information about these data.

16. Output Products and Availability:

Available via FTP or on CD-ROM.
