ESOP 1998 Station Information 1.0 General Description The GEWEX Continental-Scale International Project (GCIP) Enhanced Seasonal Observing Period (ESOP) 1998 datasets contain data collected from over six thousand stations in the ESOP 1998 domain (i.e., approximately 85W to 99W longitude and 37N to 50N latitude) for the period 01 October 1997 through 31 May 1998. The station information provided defines each station in the ESOP 1998 dataset with station location, name, frequency of observation, etc. For a complete description of the station information file format, refer to section 2.1. On 5 April 2002, the Reporting Frequency of several National Centers for Environmental Prediction (NCEP) hourly precipitation stations (Platform Type 147) were corrected. They were previously incorrectly identified as daily stations. On 5 April 2002, it was determined that the state codes for all Platform Type 46 stations were incorrect and should not be used. 2.0 Detailed Data Description None. 2.1 Detailed Format Description The following is a complete description of the station information provided with the ESOP 1998 data. Table 1 details the station list parameters. The beginning and ending dates for the period of coverage are either in Universal Time Coordinated (UTC) or local time and is network dependent. The Identification Type field is network dependent and indicates the source of the Identification field. Example Identification Types are WBAN, FAA, etc. The Occurrence field is an integer value used to indicate co-located stations. Note that when a particular parameter is unknown for a station, either a blank, a question mark, or all 9's will appear in that parameter's position. For a complete list of Country, State, and County values, refer to the documents in the references (Section 4.0). Possible platform types and frequency values are listed in Tables 2 and 3, respectively. Note that only those platform types present in the ESOP 1998 data have been listed. Table 4 lists commissioning dates for all stations commissioned (where applicable) during this project. Table 1 Parameter Description --------- ----------- Identification ID in data. Identification Type ID number type. Latitude Station Latitude. Longitude Station Longitude. Occurrence Station occurrence. Lat/Lon Accuracy Number of digits accuracy in lat/lon values. Name Expanded station name. Commissioned Flag `(C)' indicates commissioned station, `(N)' indicates station which is NOT commissioned. Table 4 contains commissioning dates for all stations commissioned during this project. Begin Period of Coverage Beginning date of period of coverage. End Period of Coverage End date of period of coverage. Country Country in which station is located. Always US or CA for ESOP 1998, where US is for United States and CA is for Canada. State State code. County County code. UTC offset Hour Offset from UTC time. DST switch 'y' indicates station does switch to Daylight Savings Time (DST). 'n' indicates station does not switch to DST. Platform type Collection Platform. Reporting Frequency Frequency of data collection. Elevation Station elevation. Fixed/Mobile flag Flag indicating if station has fixed location. 'f' indicates a fixed station. 'm' indicates a mobile station.

A complete list of these stations is given in Table 4. On 5 April 2002, the Reporting Frequency of several National Centers for Environmental Prediction (NCEP) hourly precipitation stations (Platform Type 147) were corrected. They were previously incorrectly identified as daily stations. On 5 April 2002, it was determined that the state codes for all Platform Type 46 stations were incorrect and should not be used. 3.0 Quality Control Processing Not applicable. 4.0 References Department of Commerce - National Institute of Standards and Technology (NIST), 1985: Federal Information Processing Standards Publication 10-3 Countries, Dependencies, & Areas of Special Sovereignty.
