GHRC News

GCPEx logo

GHRC published two guides from the GPM Cold-season Precipitation Experiment (GCPEx). The GPM Ground Validation Environment Canada (EC) Vaisala Ceilometer GCPEx data were collected in Huronia, Canada from January 15, 2012 through March 1, 2012. The CT25K ceilometer uses pulsed diode laser LIDAR technology to derive backscatter profiles, cloud heights and vertical visibilities. It is also able to detect 3 cloud layers simultaneously. The GPM Ground Validation Environment Canada (EC) Radiometer GCPEx dataset contains retrievals of temperature, water vapor, relative humidity, liquid water profiles and surface parameters acquired by a passive microwave radiometer. Its data were collected in Ontario, Canada February 2012 through March 1, 2012. Data plots are available in the browse files.

GHRC published the GPM Ground Validation Dual Polarized C-Band Doppler Radar King City GCPEx dataset. This dataset of observations from Environment Canada’s operational Doppler radar at King City, Ontario (WKR) has special RHI (Range Height Indicator) and sector scans of several dual polarization parameters and was created by the C-Band radar during the GPM Cold-season Precipitation Experiment (GCPEx) in Ontario, Canada. Additionally, specially configured CARE-centric composites (Environment Canada’s Centre for Atmospheric Research Experiments) were also generated. Standard WKR IRIS (Interactive Radar Information System volume and PPI (Plan Position Indicator) scans, along with corresponding standard PPI imagery, are also included. Data was collected from January 15, 2012 through March 3, 2012.

GHRC published the guide document for the GPM Ground Validation Environment Canada (EC) Radiosonde GCPEx dataset. This dataset includes measurements of temperature, pressure, humidity, and wind collected in the upper atmosphere by Vaisala RS92 Radiosondes during the GPM Cold-season Precipitation Experiment (GCPEx) at Environment Canada’s Centre for Atmospheric Research Experiments (CARE)in Ontario, Canada from January 17 to February 29, 2012.

 

Dr. Rahul Ramachandran presenting at a recent conference

GHRC welcomes new DAAC Manager Dr. Rahul Ramachandran! Rahul is well known within the DAACs, the ESIP Federation, and the Earth Science community. Rahul’s background in Earth science, computer science and informatics will serve him well. Rahul received a B.E. degree in Mechanical Engineering from JMI University, New Delhi, an M.S. in Meteorology from South Dakota School of Mines and Technology, an M.S. in Atmospheric Science, another M.S. in Computer Science, and finally a Ph.D. in Atmospheric Science from the University of Alabama Huntsville. Beyond his impressive academic credentials, he was awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) in 2009. Rahul’s research is focused on Earth Science Informatics connecting the application of computational methods and information technology to the acquisition, storage, processing, interchange, analysis and visualization of Earth Science data and information. As an Earth scientist and information technologist at the University of Alabama in Huntsville he worked almost daily with members of the GHRC. Rahul formally takes over as the DAAC Manager when he becomes a NASA civil servant on 16 December 2013. His focus on Earth Science Informatics will strengthen the DAAC and extend its reach into our research and data community.
