The NASA Global Hydrology Resource Center (GHRC) DAAC published the Global Precipitation Measurement (GPM) mission ground validation Light Precipitation Validation Experiment (LPVEx) radiosonde data set. The Vaisala radiosondes were used to produce vertical profiles of atmospheric temperature, pressure, humidity, and winds. The radiosondes were launched from two locations: Kumpula and Vantaa, Finland. The LPVEx field campaign took place around the Gulf of Finland in September and October, 2010. However, the Vantaa launch site record extends through January 2011. The campaign was to provide additional high altitude, light rainfall measurements for the improvement of GPM satellite precipitation algorithms. Data files are available in TSV format with PNG browse images. Data are available from September 15, 2010 through January 28, 2011.
