TRMM Ground Validation Radar Reflectivity Single Level Cartesian Grid 1 hour V7 (TRMM_baseUW)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/hghsfpv7ohac
This dataset is part of the University of Washington TRMM Ground Validation products.
Description
Data contains single level, cartesian grids containing output of NCAR SPRINT interpolation of lowest sweep of 1C51UW. Horizontal extent is 150x150km and horizontal resolution is 2km.
Note that in the netCDF files, "alt" (altitude) is assigned the elevation angle of the lowest sweep (which is used to create this product) and "z_spacing" has no meaning. A key component of the TRMM project is the Ground Validation (GV) effort which consists of collecting data from ground-based radar, rain gauges and disdrometers. The data is quality-controlled, and then validation products are produced for comparison with TRMM satellite products.

The four primary GV sites are: + Darwin, Australia; + Houston, Texas; + Kwajalein, Republic of the Marshall Islands; + Melbourne, Florida. A significant effort is also being supported at NASA Wallops Flight Facility (WFF) and vicinity to provide high quality, long-term measurements of rain rates (via a network of rain gauges collocated with National Weather Service gauges), as well as drop size distributions (DSD) using a variety of instruments, including impact-type Joss Waldvogel, laser-optical Parsivel, as well as two-dimensional video disdrometers.
DSD measurements are also being collected at Melbourne and Kwajalein using Joss-Waldvogel disdrometers.
