Evaporation Over A Heterogeneous Land Surface

Downscaling Meteosat Land Surface Temperature over a Heterogeneous Landscape Using a Data Assimilation Approach

A wide range of environmental applications require the monitoring of land surface temperature (LST) at frequent intervals and fine spatial resolutions, but these conditions are not offered nowadays by the available space sensors. To overcome these shortcomings, LST downscaling methods have been developed to derive higher resolution LST from the available satellite data. This research concerns t...

An Operational Remote Sensing Algorithm of Land Surface Evaporation

Rescaling the complementary relationship for land surface evaporation

Recent research into the complementary relationship (CR) between actual and apparent potential evaporation has resulted in numerous alternative forms for the CR. Inspired by Brutsaert (2015), who derived a general CR in the form y5 function (x), where x is the ratio of potential evaporation to apparent potential evaporation and y is the ratio of actual to apparent potential evaporation, an equa...

Global Land Surface Evaporation from Satellite-based Observations

Estimating the magnitude of the different fluxes in the hydrological cycle is essential if we are to predict the impacts of climate change. However, climate change is acting on a dynamic three dimensional globe where change in one region may produce impacts in another. This creates a need to expand the current climate change studies to encompass the entire globe. Evaporation is a key component ...

A Surface Reflectance Model for Aerosol Remote Sensing over Land

Aerosol remote sensing over land is based on the use of pixels covered by vegetation. Because of the absorption of the photosynthesis pigments, these pixels are quite dark in the blue and in the red. This consideration led to introduce the concept of DDV pixels. Initially, 11 DDV models have been selected from the POLDER 1 imagery. ARVI, atmospherically resistant vegetation index, has been used...
