The study of the thermal behavior of permafrost and active layer on the South Shetland Islands, in the western side of the Antarctic Peninsula (Antarctica), has been our research topic since 1991, especially after 2006 when we established different a

Evaluating the potential of MODIS-LST for monitoring ground surface temperatures in the Maritime Antarctic (Barton Peninsula, King George Island, Antarctic)
Autor: J. F. Calleja, Joana Baptista, Alejandro Corbea-Pérez, Gonçalo Vieira, Hyoungseok Lee, Carmen Recondo
Land surface temperature is an important factor for permafrost modelling as well as for understanding the dynamics of Antarctic terrestrial ecosystems (Bockheim et al. 2008). In the South Shetland Islands the distribution of permafrost is complex (Vi

Improvements in the estimation of daily minimum air temperature in peninsular Spain using MODIS land surface temperature
Autor: J. F. Calleja, Carmen Recondo, Juanjo Peón
Publikováno v: International Journal of Remote Sensing. 35:5148-5166
Air temperature (Ta) is a key variable in many environmental risk models and plays a very important role in climate change research. In previous studies we developed models for estimating the daily maximum (Tmax), mean (Tmean), and minimum air temper
