Description

The GPM Ground Validation Met One Rain Gauge Pairs OLYMPEX dataset contains precipitation amount and precipitation rate data collected during the Global Precipitation Measurement mission (GPM) Ground Validation (GV) Olympic Mountains Experiment (OLYMPEX). The OLYMPEX field campaign took place between November 2015 and January 2016, with additional ground sampling continuing through February 2016, on the Olympic Peninsula in the Pacific Northwest of the United States. The purpose of the campaign was to provide ground-validation data for the measurements taken by instrumentation aboard the GPM Core Observatory satellite. The Met One Rain Gauge Pairs are tipping bucket precipitation gauges which collect precipitation amounts and calculate precipitation rates. This dataset contains two ASCII-tsv files per rain gauge and two rain gauges are located on each station platform. The Met One Rain Gauge Pairs OLYMPEX dataset files are available from January 1, 2015 through June 20, 2016 in ASCII-tsv format.
