GHRC News

The GHRC DAAC has published a micro article describing “Highlights from Albrecht et. al's 'Where Are the Lightning Hotspots on Earth?’ publication.”  This publication in the November 2016 issue of the Bulletin of the American Meteorological Society (BAMS) described Albrecht’s research with the GHRC’s 16-year data record from the Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS).  Albrecht’s resulting data product, the LIS 0.1 Degree Very High Resolution Gridded Lightning Climatology Data Collection, is also available from the GHRC.

 

The GHRC has published 5 GPM Ground Validation Rain Gauge datasets, 3 from the Olympic Mountains Experiment (OLYMPEX) campaign and 2 from the Integrated Precipitation and Hydrology Experiment (IPHEx). The OLYMPEX datasets contain data gathered during 2015-2016 on the Olympic Peninsula in the Pacific Northwest of the United States. The IPHEx Rain Gauge datasets contain data collected during Spring 2014 from multiple sites of the Southern Appalachian region of North Carolina.

GHRC DAAC managers and engineers are participating in information gathering and analysis in support of ESDIS Cloud activities. On May 25th they attended a telecon with ESDIS and Forrester Research. Forrester will provide recommendations on ESDIS’ approach to adopt the use of public cloud by evaluating the overarching strategy and helping to validate the expected costs and benefits for moving a DAAC to the public cloud. GHRC provided information on our data archive, processes and infrastructure, and continues to answer follow-up questions. GHRC is also participating in Phase 3 of the Cumulus project, providing a comprehensive list of data products with details on ingest, archive and distribution processes for the “Cumulus Transition Decision-Making Framework” document.

GHRC DAAC published the TRMM Multi-satellite Precipitation Analysis (TMPA) IPHEx ( http://dx.doi.org/10.5067/GPMGV/IPHEX/MULTIPLE/DATA301) dataset. The IPHEx TMPA is a subset of the TMPA 3B42RT gridded precipitation product selected for the time period of the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) held in North Carolina during May 1, 2014 to June 15, 2014. The goal of IPHEx was to characterize warm season orographic precipitation regimes and the relationship between precipitation regimes and hydrologic processes in regions of complex terrain. This dataset contains 3-hourly, 0.25 degree maps of precipitation derived using microwave (MW), infra-red (IR), surface precipitation gauge measurements, and other rain products that include the TRMM Precipitation Radar (PR) data. The IPHEx TMPA product is available in netCDF-4 and binary formats.

The GHRC DAAC has published the GPM Ground Validation High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) OLYMPEX dataset (http://dx.doi.org/10.5067/GPMGV/OLYMPEX/HIWRAP/DATA101). The Olympic Mountain Experiment (OLYMPEX) was the final Global Precipitation Measurement (GPM) mission Ground Validation field campaign. HIWRAP is a Doppler radar designed to measure tropospheric winds through deriving Doppler profiles from cloud and precipitation volume backscatter. (Li et al. 2016). The winds are generated by combining conical scan mode measurements at two different frequency bands (Ka- and Ku-band) and two different incidence angles (30 and 40 degrees). HIWRAP utilizes solid state transmitters along with a novel pulse compression scheme resulting in a system that is considerably more compact and requires less power than typical radars used for precipitation and wind measurements. A more detailed description of the HIWRAP system and system parameters can be found in Li et al., 2016. More information about the HIWRAP instrument can be found at the Goddard Space Flight Center High Altitude Radar Group: https://har.gsfc.nasa.gov/index.php?section=13.
