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.

1. NOAA + NASA remote sensing of climate variables (NOAA + NASA remote sensing)

Both NOAA and NASA operate satellites with cover¬age of the Arctic region. The major observations and products are: 1. Daily, near real-time plots of surface, cloud, and radiative properties from AVHRR; 2. Near real-time MODIS and AVHRR polar winds; 3. Daily, near real-time plots of clear sky, low-level temperature inversions from MODIS; 4. Daily profile plots of Arctic temperature, humid-ity and winds; 5. Near-daily plots of surface winds over open water; and 6. Surface temperatures for land, sea and sea ice.

4. Alaska Ocean Observing System (AOOS)

To develop a coastal and ocean observing system in the Alaska region that meets the needs of multiple stakeholders by (1) serving as a regional data center providing data integration and coordination; (2) identifying stakeholder and user priorities for ocean and coastal information; (4) working with federal, state and academic partners to fill those gaps, including by AOOS where appropriate. Main gaps: AOOS and the data center are statewide activities, but thus far, available funding has limited observations and models primarily the Gulf of Alaska.

6. Beaufort and Chukchi Seas Mesoscale Meteorology Model

1. Produce a geospatial surface meteorological database for the Beaufort and Chukchi Seas and the adjacent coastal areas by collecting available conventional and unconventional surface and atmospheric data and conducting field work; 2. Establish a well-tuned Beaufort/Chukchi seas mesoscale meteorology model through further modeling studies for the optimization and improvement of the model physics and configuration; 3. Conduct a long-term hindcast simulation with the optimized data-modeling system and produce a high resolution meteorological dataset for the Beaufort and Chukchi regions; and 4. Document the high-resolution climatological features of the Beaufort/Chukchi seas’ surface winds, including an analysis of the interannual variability and long-term

7. NPS Inventory and Monitoring Program, Alaska Region

To determine status and trend in the condition of selected natural resources in national park units in Alaska. There are four networks, each encompassing activities in a set of national parks, preserves and other park lands: • Arctic Network (ARCN): Gates of the Arctic, Noatak, Kobuk Valley, Cape Krusenstern, Bering Land Bridge. • Central Alaska Network (CAKN): Yukon-Charley Rivers, Denali, Wrangell-St. Elias. • Southwest Alaska Network (SWAN): Kenai Fjords, Lake Clark, Katmai, Alagnak Wild River, Aniakchak. • Southeast Alaska Network (SEAN): Glacier Bay, Klondike Gold Rush, Sitka. Main gaps: Not all data are currently available but we are working toward that goal. Funding limitations do not allow monitoring at detailed levels.

8. Atmospheric Radiation Measurement (ARM) Climate Research Facility (ACRF) (ACRF)

The Atmospheric Radiation Measurement (ARM) Climate Research Facility (ACRF) is a multi-platform national scientific user facility, with instruments at fixed and varying locations around the globe for obtaining continuous field measurements of climate data. Each ACRF site uses a leading edge array of cloud- and aerosol-observing instruments to record long-term continuous atmospheric and surface properties that affect cloud formation and radiation transport through the atmosphere. The ARCF also provides shorter-term (months rather than years) measurements with its two mobile facilities (AMFs) and its aerial measurements. Network type: - Atmosphere, with a focus on the impact of clouds and aerosol on the Earth’s radiation budget. - Location: Primary site: Barrow, Alaska, 71° 19' 23.73" N, 156° 36' 56.70" W Secondary site: Atqasuk, Alaska, 70° 28' 19.11" N, 157° 24' 28.99" W - Community-based: No.

9. Application of Ground-based remote sensing to Arctic climate research

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)
