Remote Sensing Facility (RSF)
The RSF's mission is to serve the observational needs of the atmospheric science community by developing and deploying state-of-the-art radar and lidar instrumentation.
RSF, led by Facility Manager Wen-Chau Lee, is committed to providing and analyzing cross-cutting measurements in interdisciplinary research thereby continuing EOL’s leadership in the discipline of remote sensing.
The combination of ground-based scanning and airborne remote sensors provides measurements of atmospheric parameters essential for realization of the societal and scientific benefits outlined in the EOL Strategic Outlook.These high-resolution, large-domain, remotely-sensed observations of clear air and precipitation are otherwise unobtainable.
The S-band Polarimetric (S-Pol) radar which is equipped with dual-wavelength capability (S-band and Ka-band). The two radars take simultaneous dual-polarimetric measurements making S-Pol the only transportable radar in the world that is capable of describing air motions, boundary layer humidity, cloud initiation and precipitation microphysics.
The High Spectral Resolution Lidar (HSRL) is used to make reliable and accurate measurements of atmospheric extinction, backscatter coefficients, optical depth, and discrimination between ice and water clouds. The HSRL works by measuring laser returns and depolarization from aerosol and molecular scattering simultaneously. The molecular scattering is used as a calibration target which is available at each point in the lidar return.
The HSRL was designed and built by the University of Wisconsin Lidar Group. The instrument had successful test flights on the NCAR GV in Feb 2010. The lidar was delivered to NCAR in the summer of 2010 and installed in a sea-container where it has been operating as a ground based instrument. Real time and archived data can be viewed at the GVHSRL in Madison WI website.
The HIAPER cloud radar (HCR) is an airborne millimeter-wavelength radar that will serve the atmospheric science community by providing remote sensing capabilities to the NSF/NCAR G-V () aircraft. The radar is scheduled to be delivered in September of 2010.
EOL will use a phased approach to building the HCR. Phase A will consist of a pod mounted W-band Doppler radar. Additional phases are currently unfunded. Pulsecompression and polarimetric capability are planned for phase B, and a second wavelength (Ka-band) is planned for phase C.
