The Olympics Mountain Experiment (OLYMPEX), the last of the planned Ground Validation field experiments for the Global Precipitation Measurement (GPM) mission, began in mid-November and will continue through February 2016. The Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) developed and is maintaining the OLYMPEX portal, a collaboration site that enables science teams to upload a variety of planning materials, including daily forecast presentations, plan of the day reports, mission scientist and instrument reports. Flight reports from the NASA Ames Mission Tool Suite (MTS) are being collected into the portal as well. GHRC is ingesting and making available for display on the portal several low latency ancillary datasets, including GOES imagery and radar data from National Weather Service stations. All OLYMPEX data products will be archived at GHRC DAAC for public access as part of the GPM GV collection.
