CELS/ARM Climate Research Facility
"The Mid-Latitude Continental Convective Clouds Experiment from a NASA Global Precipitation Measurement Perspective"

DATE: June 23, 2011 to June 23, 2011
TIME: 3:00 PM - 4:00 PM
SPEAKER: Stephen Nesbitt, Assistant Professor, Department of Atmospheric Sciences, University of Illinois
LOCATION: Building 240, Conference Room 1404/1405, Argonne National Laboratory
HOST: Dr, Scott Collis

Description:
In this presentation, an overview of the Global Precipitation Mission's ground validation (GPM-GV) program will be discussed, including its scientific rationale and implementation strategy. GPM is planned to launch in mid-2013, and "day 1" retrieval algorithms are currently being developed for the new Ku-Ka dual-frequency precipitation radar and high frequency passive microwave sensors (>95 GHz) to be deployed on the core satellite. Validation data are being collected pre-launch in a series of GV experiments spanning a range of precipitation regimes over both land and ocean. The Mid-Latitude Continental Convective Clouds Experiment (MC3E), conducted jointly between the Department of Energy Atmospheric Systems Research (ASR) program and the NASA-GPM project from April-June 2011, successfully collected over a dozen cases of precipitation proximate to the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) facility in north-central Oklahoma, as well as coordinated aircraft sampling over the broader southern and high plains of the United States. Constituting a major field campaign in the GPM-GV program, preliminary results from the MC3E field campaign will be presented, as well as a perspective on how continued collaboration between DOE ASR and NASA-GPM can mutually benefit both programs.
