Monthly Land Surface Temperature from MODIS, 2007-2013, Circum-Arctic Region

Duguay, Claude R.; Soliman, Aiman; Hachem, Sonia; Saunders, William

Monthly land surface temperature (LST) products of the ESA Data User Element (DUE) Permafrost are provided at 1 km spatial resolution for the Alaska, Mackenzie, Laptev Sea Coast, and Ob Estuary regions and at 25 km resolution for the circum-Arctic region. Products include monthly averages from 2000 to 2013 from which annual averages can also be calculated. Monthly LST averages were calculated from MOD11_L2 and MYD11_L2 LST (Version 5 from NASA Terra and Aqua satellites) products at 1 km resolution. Regional products are also available with weekly temporal resolution.

Each LST file contains 6 bands: bands 001, 003, 005 contain the LST averages and bands 002, 004, 006 provide supplementary quality information.

Known issues: the LST data are all measured during clear-sky conditions. The influence of clouds on surface temperature (e.g. temperature warmer under clouds in winter) is not reflected in the LSTs. This makes the LST colder than in reality due to the isolative effect of clouds.

More information about image processing and classification can be found in the product guide.

LST products are also available with weekly temporal resolution.

This dataset is part of the ESA DUE Permafrost Full Product Set (doi:10.1594/PANGAEA.780111).
