[1] A 30-year satellite record of sea ice extents derived mostly from satellite microwave radiometer observations reveals that the Arctic sea ice extent decreased by 0.30 ± 0.03 10 km/10 yr from 1972 through 2002, but by 0.36 ± 0.05 10km/10yr from 1979 through 2002, indicating an acceleration of 20% in the rate of decrease. In contrast, the Antarctic sea(More)
Global sea ice products are produced from the Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) onboard both the Terra and Aqua satellites. Daily sea ice extent and ice surface temperature (IST) products are available at 1and 4-km resolution. Validation activities during the “cold period” (when meltwater is generally not(More)

[1] We present a new technique to study the seasonal cycle of climatic trends in the expected value, variance, and other moments of the statistical distribution. The basis of the technique is multiple linear regression, but with periodic basis functions. The technique allows us to provide comprehensive information on statistical parameters of climate for(More)
[1] Comparison of polar sea ice results from 11 major global climate models (GCMs) and satellite-derived observations for 1979–2004 reveals that each of the models is simulating annual cycles that are phased at least approximately correctly in both hemispheres. Each is also simulating various key aspects of the observed ice cover distributions, such as(More)
In 1985 the NASA Sea Ice Algorithm Working Group (NSAWG) reviewed the state of passive microwave sea ice algorithm development for the purpose of recommending an algorithm for deriving sea ice products from the new DMSP SSM/I. The NSAWG chose three candidate algorithms that had been developed and tested, and selected one of these for processing the SSM/I(More)
Surface elevation and roughness measurements from NASA’s Ice, Cloud, and land Elevation Satellite (ICESat) are compared with high-resolution airborne laser altimeter measurements over the Arctic sea ice north of Alaska, which were taken during the March 2006 EOS Aqua Advanced Microwave Scanning Radiometer sea ice validation campaign. The comparison of the(More)
