Two GCPEX Dataset Publications completed

GHRC has completed publication of two GCPEX (Global precipitation mission Cold-season Precipitation EXperiment) datasets, GPM Ground Validation Autonomous Parsivel Unit (APU) GCPEx and GPM Ground Validation Pluvio Precipitation Gauge GCPEx. The GPM Ground Validation Autonomous Parsivel Unit (APU) GCPEx dataset collects data by an optical disdrometer based on single particle extinction that measures particle size and fall velocity. This APU consists of the Parsivel, which was developed by Ott Hydomet in Kempton, Germany, and its support systems, which were designed and built by the University of Alabama in Huntsville. The APU dataset for the GCPEX provides precipitation data including raindrop size and counts, precipitation drop size, rate and amount and snowflake size, counts and distribution. The GCPEx APU data was collected from several sites in Canada during the Winter 2011-2012 period.

GCPEX Pluvio Precipitation Gauge Dataset Published

GHRC has published the GPM Ground Validation Pluvio Precipitation Gauge GCPEx. The Pluvio rain gauge dataset contains both one minute measurement and a cumulative record of the accumulation and intensity for liquid, solid, and mixed precipitation collected during the GPM Cold-season Precipitation Experiment (GCPEx). GCPEx took place in Ontario, Canada during the Winter season December 2011- February 2012 where data was collected at five sites: Environment Centre for Atmospheric Research Experiments (CARE), Huronia, Steamshow, Skydive and Morton. The new generation Pluvio was designed by Ott Hydromet in Kempten, Germany.

GHRC Represented at NG-CHC Meeting

Dr. Sara Graves, Sandra Harper and Manil Maskey represented GHRC at the Northern Gulf Coastal Hazards Collaboratory meeting in Mobile, AL, June 12-14. The NG-CHC - a collaborative environment for the coastal hazards research community in Louisiana, Mississippi, and Alabama - has been developed to advance the science and engineering of coastal hazards across the region, including engineering design, coastal system response, and risk management of coastal hazards. Two graduate student researchers with the University of Alabama in Huntsville’s Information Technology & Systems Center presented posters. Prabhash Jha presented Coastal Hazard Events Driven Automated Data Aggregation, Processing, and Delivery, which leverages Event Driven Data Delivery (ED3) initially prototyped at the GHRC, and Sabin Basyal presented NG-CHC Simulation Experiment Integration. GHRC is a partnership between NASA MSFC and UAH ITSC. ITSC also leads the development of the collaborative environment for NG-CHC.

GHRC Represented at IGARSS Meeting

Dr. Rahul Ramachandran (UAH/ITSC) represented GHRC at IGARSS in Melbourne, Australia 19-26 July. He presented “Provenance as a Guide to Understanding Science Data” in the invited session “Ensuring Credibility of Remote Sensing Data Products” convened by Drs. Hampapuram Ramapriyan and Curt Tilmes of NASA. Co-authors included Helen Conover, Michael Goodman and additional GHRC staff. Dr. Ramachandran’s other papers were “Visual Analytics Toolbox for Data-Intensive Analysis”; “Polaris: A Discovery Engine For Big Data” describing a tool prototyped at GHRC; and “Data Intensive Science In Action - A Demonstrative Use Case Using 20+ Years Of SSMI(S) Global Ocean Daily Composite Fields”, the RSS DISCOVER MEaSUREs dataset archived at GHRC.
