    Top of Page About Land-based Data

    Land-based observations contain various meteorological elements that over time describe the climate of a location or region. These elements include temperature, dew point, relative humidity, precipitation, snowfall, snow depth, wind speed, wind direction, cloudiness, visibility, atmospheric pressure, evaporation, soil temperatures, and various types of weather occurrences such as hail, fog, thunder, etc. This also includes data observed by weather radars. The weather observations vary in their time interval from sub-hourly to hourly to daily to monthly. Summaries are then produced from these data. Land-based data from around the world are archived at NCDC. For an even more comprehensive listing of data products that includes land-based data, upper air data and marine data you may visit our Online Climate Data Directory.
