Application of Ground-based remote sensing to Arctic climate research

Updated 2000-04-24

This research consists of eight projects. 1. Climate-related remote sensing of clouds. A project to extend and test innovative techniques for observing cloud microphysical properites from ground-based cloud radar, lidar, and radiometers (P.I. Brooks Martner +1-303-497-6375) 2. Ground-based and remote sensing of microphysical and radiative properties of Arctic clouds. This project involves data analysis of radar, lidar, and radiometer data from the FIRE-III Arctic Cloud Experiment, including in situ validation with aircraft, and development of retrieval techniques of cloud microphysical properties from satellite data. (P.I. Taneil Uttal, +1-303-497-6409) 3. Deployment of surface based, active remote sensors during SHEBA. Data collected in 1997-1998 will be analyzed to provide information on cloud boundaries, radar reflectivities, radar Doppler velocities, lidar depolarization ratios, and lidar backscatter. (P.I. Taneil Uttal, +1-303-497-6409) 4. Validation of CERES cloud retrievals over the Arctic with surface-based millimeter-wave radar. The goal is to provide long-term data sets to validate satellite data from the CERES package on the TERRA satellite. (P.I. Taneil Uttal, +1-303-497-6409) 5. Development of an integrated sounding system in support of the DOE/ARM program. Microwave and millimeter wave radar data sets are being collected to study water vapor and Arctic clouds under Arctic winter conditions. (P.I. Ed Westwater, +1-303-497-6527) 6. Application of Kalman filtering to derive water vapor profiles from combined ground-based sensors. The goal is to improve calibration methods for the ARM microwave radiometers. (P.I. Ed Westwater, +1-303-497-6527) 7. Meltpond 2000. The goal is to use aircraft-based radiometers to obtain the first high spatial resolution microwave images of polynas to improve the interpretation of SSM/I and SSMIS imagery of Arctic ice. (P.I. Al Gasiewski, +1-303-497-3577) 8. Arctic atmospheric radiation studies. This collaboration with the Japanese Communications Research Laboratory provides for ground-based measurement of ozone, water vapor and cloud radiation. (P.I. Joe Shaw, +1-303-497-6496)
