Abstract Description: Map of estimated mean daytime air temperature at 2-m height [Degree C], August 30, 2009, PACA Region. The layer was generated from input satellite MSG-SEVIRI images (provided by EUMETSAT) 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). Hourly MSG-SEVIRI images acquired between 8 am and 5 pm were used. For each pixel, first air temperature was separately estimated from each hourly MSG-SEVIRI 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.
