Greenland Ice Surface Temperatures, 2000-2014
The image gallery below shows the mean-monthly ice surface temperature (IST) of the Greenland Ice Sheet (left image), and the number of days of data available that month for each grid cell (right image). The daily and monthly IST data are available in the zip files linked below each thumb image.
The dataset has been updated recently to provide ISTs and melt maps at 1.5-km resolution. Some additional manual cloud screening has also been done, beyond the cloud screening that was done in the previous dataset which was provided at 6.25-km resolution and is described in Hall et al. (2012 and 2013).
The link titled 'Flat Binary Files' contains the daily IST data, the monthly average IST data, and number of days available for each monthly averaged grid cell. Color-coded images of each of these flat binary data files are also included.
The link titled 'GeoTIFF Files' contains georeferenced TIFF versions of the daily IST, the monthly average IST, and the number of days available.
Additionally, the entire dataset can be be downloaded via the 'Download All' link.
Ancillary data is available in the 'Ancillary Information' link, which contains the latitude, longitude, land/ice sheet mask, and the DEM data corresponding to the IST data.
