Abstract :
Precipitation is an important part of hydrologic cycle in global scale or regional scale. Although satellite-based observation is able to provide spatial and temporal distribution of precipitation, the satellite measurements tend to show systematic bias. A fusion method for mapping precipitation is introduced in this paper. The thin plate smoothing spline interpolation method is introduced to combine rainfall gauge and TRMM Multisatellite Precipitation Analysis (TMPA) data and map daily precipitation over china mainland region. With combined gauge data, the new daily precipitation provide more reliable high temporal/spatial resolution precipitation estimates.
