The present study received support from the CNES (Centre National d’Etude Spatiale, France).

Reference for the model:

Boulet, G., Mougenot, B., Lhomme, J.P., Fanise, P., Lili-Chabaane, Z., Olioso, A., Bahir, M., Rivalland, V., Jarlan, L., Merlin, O., Coudert, B., Er-Raki, S., Lagouarde, J.P., 2015. The SPARSE model for the prediction of water stress and evapotranspiration components from thermal infra-red data and its evaluation over irrigated and rainfed wheat. Hydrol. Earth Syst. Sci., 19(11): 4653-4672.



The SPARSE model is coded in Matlab language; it computes the energy budget components for two sources (soil and vegetation) from surface (Leaf Area Index, vegetation height) and meterological forcing data.
