The Terrain-induced Rotor Experiment (T-REX) 2006 Data sets contain data collected from over 1100 stations in the T-REX 2006 domain and time period. The station information provided defines each station in the T-REX 2006 data sets with station location, name, frequency of observation, etc. For a complete description of the station information file format, refer to Section 2.1.
The following is a complete description of the station information provided with the T-REX 2006 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 T-REX 2006 data have been listed.
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. 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 is for United States. 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.

The station locations were provided by the data source agencies unless otherwise specified here.
The station locations for China Lake ASOS came from the AirNav web site.
The station locations for the Automated Surface Observing System (ASOS) data came from two station lists: the "NCDC Multi-network Metadata System" list and the "Integrated Surface Hourly Database Station History" list. If a station was on both lists, the "NCDC Multi-network Metadata System" locations were used.
The station locations included with the Unidata Local Data Manager (LDM) World Meteorological Organization (WMO) (LDMSFCMETR) data come form a variety of sources including the station list developed by Steve Chiswell at UNIDATA for GEMPAK.
