Lake-ICE Station Information 1.0 General Description The Lake-Induced Convection Experiment (Lake-ICE) datasets contain data collected from 1624 stations in the Lake-ICE domain (i.e., approximately 37N to 55N latitude and 73W to 104W longitude) for the period 28 November 1997 through 25 January 1998. The station information provided defines each station in the Lake-ICE dataset with station location, name, frequency of observation, etc. For a complete description of the station information file format, refer to section 2.1. 2.0 Detailed Data Description None. 2.1 Detailed Format Description The following is a complete description of the station information provided with the Lake-ICE 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 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 Lake-ICE 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. US for United States, CA 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. 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.
