POSS LPVEx Published

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Precipitation Occurrence Sensor System (POSS) LPVEx dataset. This dataset consists of precipitation and radar parameter estimates for both liquid and solid precipitation. Measurements were collected by the Precipitation Occurrence Sensor System (POSS) during the Global Precipitation Measurement (GPM) mission Light Precipitation Validation Experiment (LPVEx) field campaign. This field campaign took place around the Gulf of Finland in September and October of 2010. The goal of the campaign was to provide additional high-latitude, light rainfall measurements for the improvement of GPM satellite precipitation algorithms. The POSS dataset files are available from September 18, 2010 through April 20, 2011 for two POSS sites: Emasalo and Jarvenpaa. The data files are in CSV format with browse imagery in PNG format. It should be noted that the LPVEx field campaign officially took place in September and October 2010, but individual data sets, such as the POSS dataset discussed here, provided data beyond the campaign.
