The NASA Global Hydrology Resource Center (GHRC) Distributed Active Archive Center (DAAC) published the GPM Ground Validation Kumpula Mast Meteorological Data LPVEx dataset. This dataset comprised of temperature, radiation, and wind measurements collected by the Station for Measuring Ecosystem-Atmosphere Relations III (SMEAR III) Kumpula Mast in Helsinki, Finland. This occurred during the Global Precipitation Measurement (GPM) mission Light Precipitation Validation Experiment (LPVEx) field campaign. This field campaign took place around the Gulf of Finland, aiming to provide additional high-latitude, light rainfall measurements for the improvement of GPM satellite precipitation algorithms. These meteorological dataset files are available from September 17 through October 21, 2010 in ASCII text format. It should be noted that these dataset files are not available for each day of the campaign period. Missing dates include: 09/23/10 - 10/10/10, 10/13/10, and 10/15/10 - 10/18/10.
