In addition to the monthly data derived from the CLIMAT messages and forwarded by the monitoring centers, NCDC also acquires historical monthly and daily observations for the GSN stations. Parameters available typically include minimum, maximum, and mean temperatures, station and sea level pressures, winds, and precipitation.
