Abstract:
The High Resolution Dynamics Limb Sounder (HIRDLS) aboard the EOS Aura spacecraft was launched July 15, 2004. The instrument is designed to scan the Earth limb at multiple azimuth angles, measuring infrared emissions in 21 channels ranging from 6.12 to 17.76 microns in the upper troposphere, stratosphere and mesosphere. These measurements are used to determine the concentrations of O3, H2O, CH4, ... N2O, NO2, HNO3, N2O5, CFC-11, CFC-12, and aerosols; atmospheric temperature; geopotential height and the locations of polar stratospheric clouds and cloud tops. The vertical resolution of the HIRDLS data is about 1 km, and the spatial coverage is near-global (-64 degrees to +80 degrees latitude), with each profile spaced about 100 km along the orbit track. The HIRDLS2 product is available from the GES DISC (http://disc.gsfc.nasa.gov/Aura/HIRDLS/hirdls2_006.shtml).
At this time, temperature, ozone (O3), nitric acid (HNO3), CFC-11, CFC-12, cloud top pressure, geopotential height (GPH), and aerosol extinction (at 12.1 microns) are reported in the HIRDLS2 v006 data product.
Description:
The WAISCORES project is part of the National Science Foundation Office of Polar Programs' West Antarctic Ice Sheet (WAIS) initiative, which is aimed at understanding the influence of the West Antarctic ice sheet on climate and sea level change. WAISCORES researchers acquired and analyzed ice cores from the Siple Dome, in the Siple Coast region, West Antarctica. These cores allow researchers to distinguish local from regional influences on the climate records recovered from the cores. Drilling for the Siple Dome core began in November 1996 and finished in January 1999. The core site is located between ice streams C and D at approximately 81" 40' S and 148" 49' W. Preliminary studies indicate that the paleoclimate record preserved in the 1003-meter Siple Dome ice core extends back more than 90 thousand years. Data are available via FTP
Description:
The Antarctic Glaciological Data Center (AGDC) staff and the U.S. ITASE community are developing a data management plan for U.S. ITASE data. Archiving of these data will ensure that:
U.S. ITASE PIs and their data sets receive data management support during the proposed period of exclusive use. The AGDC will provide password-protected access to an ftp storage site for use by U.S. ITASE investigators only.
U.S. ITASE data will be available to the broader scientific community with full data management support following the period of exclusive use.
