Satellite‐Based Assessment of Methane Emissions From the Darvaza Gas Crater
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Methane is a potent greenhouse gas, and the Darvaza crater in Turkmenistan is a rare, persistent emitter. There are uncertainties regarding its formation date (either 1963 or 1971), fire ignition, and the fire's influence on methane release. Using historical Landsat imagery, we reconstruct the fire history, identifying that combustion began ...

Alaska‐Yukon Glacier Depths From a Decade of Airborne Radar Sounding
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.Abstract NASA's Operation IceBridge employed airborne radar sounders in Alaska and adjacent northwestern Canada between 2012 and 2021 to measure the thickness of the region's glaciers. Here we present the first comprehensive analysis of these data, analyzing ∼31,700 linear‐km of radar profile data to provide over 5,500 linear‐km of ice thickness and ...

Desertification monitoring by LANDSAT TM satellite imagery
Forest Science and Technology, 2011 The desertification tendency of the Qubqi Desert in China for 10 years was investigated using vegetation and soil change indices extracted from seven LANDSAT TM images. To identify the desertification tendency, two methods were applied. In the first, the desertification extent and tendency were determined by classifying the land cover into the ...
