GHRC News

Sherry Harrison and Helen Conover attended the Land Atmosphere Near-real-time Capability for EOS (LANCE) User Working Group telecon on April 25, representing the LANCE AMSR2 element of the AMSR Science Investigator-led Processing System (SIPS) at the GHRC DAAC. Harrison presented recent accomplishments, current status and plans for LANCE AMSR2. Will Ellett, GHRC’s project manager for the Lightning Imaging Sensor on the International Space Station (ISS LIS), also attended, to support ISS LIS PI Dr. Richard Blakeslee (NASA/MSFC) in his discussion of planned near real time processing and distribution of ISS LIS data by the GHRC.

The NASA Global Precipitation Measurement Mission (GPMGround Validation (GV) program, as a member of the broader NASA Precipitation Measurement Mission, is providing ground and airborne precipitation datasets supporting physical validation of satellite-based precipitation retrieval algorithms.

The requisite GV measurements include multi-frequency dual-polarimetric radar (S, C, X, Ka/Ku and W bands), airborne microphysical probe, radar and radiometer observations (e.g., provision of a GPM core satellite "proxy"), and ground-based disdrometer and raingauge network observations as a core instrument and measurement complement.

The GPM-GV instrument suite was deployed in numerous field campaigns in several different precipitation regimes. In addition to the ones listed below, these campaigns and regimes also include the NOAA Hydrometeorological Testbed-Southeast campaign (HMT-SE; North Carolina, Summer 2014) as well as international partner-lead field efforts such as the GPM-Brazil CHUVA campaign (2009-2013).

The associated GV measurements and observational strategies seek to advance our physical understanding of precipitation processes and assure consistency between this understanding and the representation of those physical processes in NASA GPM retrieval algorithms. The GPM Ground Validation program also supports a Validation Network (VN) that currently matches TRMM Microwave Imager (TMI) rain rate and Precipitation Radar (PR) reflectivity and rain rate to ground‑based meteorological radars.

Additional GPM-GV datasets are available here, including APU, JW, C3VP, TWP-ICE, and 2DVD datasets.

 

The GHRC Science Team met with several individuals from the NASA SERVIR program on April 25 to define organizational goals, determine potential areas of collaboration, and understand how GHRC can better cater towards applied Earth science user needs.

GHRC staff met with the NASA Marshall Space Flight Center DEVELOP team to share program information and discuss future collaborations. DEVELOP is a training and development program sponsored by NASA's Earth Science Applied Sciences Program. In particular, GHRC staff scientists presented a proposal to assist with a fall and spring term DEVELOP project in collaboration Dr. Patrick Gatlin (NASA/MSFC) in which a lightning vulnerability map will be produced for the Hindu-Kush region of the Himalaya.

GHRC DAAC staff published a new data recipe titled "Using ArcGIS to Convert LIS Very High Resolution Gridded Lightning Climatology NetCDF Data to GeoTIFF Format".  This publication gives step-by-step instructions for transforming in ArcMap the Lightning Climatology data constructed using 17-years of TRMM Lightning Imaging Sensor data.  The climatology and LIS data are available at the GHRC DAAC.
