TL;DR: The AMSR-E sensor calibration and extent of radio frequency interference are currently being assessed, to be followed by quantitative assessments of the soil moisture retrievals, which will provide evaluations of the retrieved soil moisture and enable improved hydrologic applications of the data.

TL;DR: The International Bathymetric Chart of the Arctic Ocean (IBCAO) released its first gridded bathymetric compilation in 1999 as discussed by the authors, which has since supported a wide range of Arc...

TL;DR: The discovery of the 2012 extreme melt event across almost the entire surface of the Greenland ice sheet is presented in this article, where data from three different satellite sensors, including the Oceansat-2 scatterometer, the Moderate-resolution Imaging Spectroradiometer, and the Special Sensor Microwave Imager/Sounder, are combined to obtain composite melt maps.

TL;DR: In this article, the amount of solar energy absorbed in areas of open water in the Arctic Basin has varied spatially and temporally over the past few decades, and the largest increases in total yearly solar heat input, as much as 4% per year, occurred in the Chukchi Sea and adjacent areas.

TL;DR: In this article, the extent of Arctic perennial sea ice, the year-round ice cover, was significantly reduced between March 2005 and March 2007 by 108 x 10 6 km 2, a 23% loss from 469 × 106 km 2 to 361 × 10 6 cm 2, as observed by the QuikSCAT/SeaWinds satellite scatterometer (QSCAT).
