Directory entires that have specified Alaska as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

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)
