Uji Plagiasi_Utilization of Global Satellite Mapping of Precipitation (GSMap) for Schmidt-Ferguson Climate Classification in South Kalimantan, Indonesia

Abstract

Distribution and density of unfamiliar observation post network, the lack of data and non-continuous data becomes problem in conducting analysis and making information of climate classification in South Kalimantan. One technique to obtain rainfall data today is by using satellite data. one of the rainfall prediction techniques using satellite data is GSMaP. Utilization of GSMaP data is an alternative data that needs to be studied to overcome the limitations of surface observation data. Data validation is done using statistical method by analizing the correlation value (r) and RMSE (Root Mean Square Error). Climation zonation based on climate classification Schmidt Ferguson. Schmidt Ferguson climate classification calculation from GSMaP data mapped spatially using Arc GIS software 10.2. GSMaP satellite rainfall data validation and surface rainfall showed a high correlation value for monthly average with correlation value 0,89 and RMSE 41,8mm/month (1,66mm/day). Schmidt Ferguson climate zoning based on GSMaP satellite data in southern Kalimantan is divided into 3 climate zones, namely type A, B and C.
