This subdirectory contains four station inventory files (*.inv). The first (temp.statinv) provides a list of the 6039 stations associated with the mean monthly temperature data set. The second (precip.statinv) provides a list of the 7533 stations associated with the total monthly precipitation data set. The third (press.sea.statinv) provides a list of the 1883 stations associated with the mean monthly sea level pressure data set. The fourth (press.sta.statinv) provides a list of the 1873 stations associated with the mean monthly station pressure data set.
Each file contains essential information about each station, including country identification number, station identification number, station name, latitude, longitude, elevation, first year of record, last year of record, and percent of data missing. The presence or absence of major discontinuities in each time series is also noted. The station inventory files can be read using the following FORTRAN IV code:
INTEGER COUNTRY, STATION, ELEV, FIRST, LAST, DISC
REAL LAT, LON, MISSING
CHARACTER * 25 NAME
READ (1, 1, END=99) COUNTRY, STATION, NAME, LAT, LON, ELEV,
*FIRST, LAST, MISSING, DISC
1 FORMAT (I3, I7, 2X, A25, 1X, F6.2, 1X, F7.2, 1X, I4,
*1X, I4, 1X, I4, 1X, F4.1, 1X, I1)
These files can also be read using the following SAS code:
INPUT COUNTRY 1-3 STATION 4-10 NAME $ 13-37 LAT 39-44 LON 46-52 ELEV 54-57
FIRST 59-62 LAST 64-67 MISSING 69-72 DISC 74;
Stated in tabular form, the contents include the following:

where
COUNTRY |
is a three-digit country code (e.g., 404 = United States of America, etc.). |
STATION |
is a seven-digit station identification number. In most cases, the last two digits of this variable are 00, and the first five digits are the station's normal WMO number (e.g., 1234500). For some stations, no WMO number was currently in use. In these cases, the last two digits of STATION are other than 00, and the first five digits are the WMO number of the nearest active WMO station (e.g., 1234501). |
NAME |
is the name of the station. |
LAT |
is the latitude of the station in decimal degrees. Stations in the Southern Hemisphere have negative latitudes. |
LON |
is the longitude of the station in decimal degrees. Stations in the Western Hemisphere have negative longitudes. |
ELEV |
is the elevation of the station in meters. Missing elevations are coded as -999. |
FIRST |
is the first year for which data are available at this station. |
LAST |
is the last year for which data are available at this station. |
MISSING |
is the percent of the record with missing data. |
DISC |
is a code which can be used to identify a time series which contains a "gross" discontinuity (i.e., one which was readily identified when the time series was plotted and analyzed visually). If DISC is 1, then the station has a major discontinuity. If DISC is 0, then the station has no major discontinuities. However, it could still contain more subtle discontinuities. |
