Analyse comparative des données pluviométriques in-situ vs les produits satellitaires TRMM3B42 pendant la saison des pluies au Mato Grosso.

Abstract : The validation of the algorithm TRMM3B42 is made from a hundred stations operated by the ANA across Mato Grosso for January of 2005 to 2008. Each precipitate volume in a grid cell satellite (0,25 ° * 0, 25 °) is compared statistically with the values of specific ground data. There is an average correlation R of 0.67 over the period studied. Bias and RMSD means are respectively 0.24 mm and 18.11 mm. The SKILL are fairly low, others techniques for validation of rainfall algorithms are then considered. The temporal analysis of statistical criteria shows that there is noticeable variation of quantitative estimates of rainfall by satellite as a function of time intervals.
