ATLAS_PACA_MEAN_TEMPERATURE_MODIS

Map of estimated monthly mean daytime air temperature at 2-m height [°C], March 2009, PACA Region. The layer was generated from input satellite MODIS images (provided by NASA) and in-situ temperature measurements (collected by Meteo France and provided by ARMINES) through the application of a supervised regression techique based on support vector machines (SVM). Daytime MODIS acquisitions are daily. For each pixel, first air temperature was separately estimated from each daily MODIS observation not affected by cloud cover, and, then, the mean of the resulting estimates was displayed in the present layer. Pixels in which cloud cover was present at all observation times and sea areas were masked out. Scientific reference: G. Moser and S. B. Serpico.
