The metadata has been carried over from GHCN-Monthly v2. This would include basic geographical station information such as latitude, longitude, elevation, station name, etc., and also extended metadata information, such as surrounding vegetation, etc.

Variable definitions:
ID: 11 digit identifier, digits 1-3=Country Code, digits 4-8 represent the WMO id if the station is a WMO station. It is a WMO station if digits 9-11="000".
LATITUDE: latitude of station in decimal degrees
LONGITUDE: longitude of station in decimal degrees
STELEV: is the station elevation in meters. -999.0 = missing.
NAME: station name
GRELEV: station elevation in meters estimated from gridded digital terrain data
POPCLS: population class
(U=Urban (>50,000 persons);
(S=Suburban (>=10,000 and <= 50,000 persons);
(R=Rural (<10,000 persons)
City and town boundaries are determined from location of station on Operational Navigation Charts with a scale of 1 to 1,000,000. For cities > 100,000 persons, population data were provided by the United Nations Demographic Yearbook. For smaller cities and towns several atlases were uses to determine population.
POPSIZ: the population of the city or town the station is location in (expressed in thousands of persons).
TOPO: type of topography in the environment surrounding the station, (Flat-FL,Hilly-HI,Mountain Top-MT,Mountainous Valley-MV).
STVEG: type of vegetation in environment of station if station is Rural and when it is indicated on the Operational Navigation Chart (Desert-DE,Forested-FO,Ice-IC,Marsh-MA).
STLOC: indicates whether station is near lake or ocean (<= 30 km of ocean-CO, adjacent to a lake at least 25 square km-LA).
OCNDIS: distance to nearest ocean/lake from station (km).
AIRSTN: airport station indicator (A=station at an airport).
TOWNDIS: distance from airport to center of associated city or town (km).
GRVEG: vegetation type at nearest 0.5 deg x 0.5 deg gridded data point of vegetation dataset (44 total classifications).
