Satellite-derived changes in the permafrost landscape of central Yakutia 2000–2011: Wetting, drying, and fires
The focus of this research has been on detecting changes in lake areas, vegetation, land surface temperatures, and the area covered by snow, using data from remote sensing in Central Siberia. Remote sensing products were used to analyze changes in water bodies, land surface temperature (LST), and le...

The focus of this research has been on detecting changes in lake areas, vegetation, land surface temperatures, and the area covered by snow, using data from remote sensing in Central Siberia.

The remote sensing analyses (for LST, snow cover, LAI, and fire) were based on MODIS–derived NASA products (250–1000 m) for 2000 to 2011. Changes in water bodies were calculated from two mosaics of (USGS) Landsat (30 m) satellite images from 2002 and 2009.
