EOSDIS Data News - 06/29/2018
NASA's Global Hydrology Resource Center (GHRC) Distributed Active Archive Center (DAAC) published the GPM Ground Validation TRMM 2A25 NRT Precipitation Radar IPHEx dataset. These data are estimates of instantaneous three-dimensional distribution of rain from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR). The TRMM 2A25 near real-time (NRT) orbital precipitation radar data from NASA GES DISC have been extracted for the southeast US region for May 1 to June 16, 2014 during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign. This data product contains the average rainfall rate between two predefined altitudes derived from each radar beam position. Other output data include parameters of Z-R relationships (R=aZb), integrated rain rate of each beam, range bin numbers of rain layer boundaries, and many intermediate parameters. Data files are available in HDF-4 format, while corresponding browse images are also available in PNG format. It should be noted that this dataset is constructed from the NASA GES DISC data. Please refer to Section 2-3.8 in the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar Algorithm Instruction Manual For Version 7 document (http://www.eorc.jaxa.jp/TRMM/documents/PR_algorithm_product_information/pr_manual/PR_Instruction_Manual_V7_L1.pdf) regarding caveats about the 2A25 algorithm and for more information on the data.
