GPM Ground Validation Advanced Microwave Radiometer Rain Identification (ADMIRARI) GCPEx Table of Contents
The GPM Ground Validation Advanced Microwave Radiometer Rain Identification (ADMIRARI) GCPEx data set includes measurements of brightness temperatures, radar reflectivity, and cloud altitude. The data was collected using ADMIRARI, Micro Rain Radar (MRR), and cloud lidar during the period of January 14, 2012 to February 29, 2012 for the GPM Cold-season Precipitation Experiment (GCPEx) at the Centre for Atmospheric Research Experiments in Ontario, Canada. The information is available in .asc ASCII space delimited table files. The following example shows how to cite the use of this data set in a publication. For more information, please see our Citing GHRC DAAC and Data page.
The GPM Cold-season Precipitation Experiment (GCPEx) occurred in Ontario, Canada during the winter season of 2011-2012. GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. These data sets were collected to aid in the achievement of the over arching goal of GCPEx which is to characterize the ability of multi-frequency active and passive microwave sensors to detect and estimate falling snow. During GCPEX, the ADMIRARI was located at the CARE facility in Ontario, Canada. The coordinates of the CARE site are: Lat: 44°13'59.45"N, Lon: 79°46'50.11"W. Data was collected from Jan 14, 2012 through Feb 29, 2012. Further details on GCPEx are available at http://gpm.nsstc.nasa.gov/gcpex. Information on the Global Precipitation Measurement (GPM) mission is available at http://pmm.nasa.gov/GPM. The ADMIRARI (ADvanced MIcrowave RAdiometer for Rain Identification), created by Radiometer Physics GmbH, is a passive microwave radiometer designed to measure water vapor, cloud and liquid rain water with a temporal resolution of 1 second and a spatial resolution of 5°. The ADMIRARI measures brightness temperatures at 10.7, 21.0 and 36.5 GHz frequencies and at two polarized planes (H and V). The radiometer is equipped with two auxiliary active instruments: a Micro Rain Radar (MRR) at 24.1 GHz frequency for rain structure observation and a cloud lidar at 920 nm wavelength for cloud base estimation. The radiometer typically provides rain/cloud liquid water path (LWP) and integrated water vapor (IWV), including total LWP and IWV for low water content cases. Additional information about the ADMIRARI is available at http://www2.meteo.uni-bonn.de/admirari/.
