Daftar Isi:
- This study has compared monthly precipitations from in-situ observation in the Palembang city and those derived from Tropical Rainfall Measuring Mission (TRMM) for a period of January 1998 - December 2008. This study used two rain gauges, in the Sultan Mahmud Badaruddin II (SMB) and Kenten station. A statistical analysis, includes a correlation analysis, a Mean Bias Error (MBE) and a regression analysis, was employed in this study. The result shows that the TRMM data significantly correlates with rain gauges data. The coefficient correlation between TRMM data and SMB data and also Kenten data were 0.7366 and 0.6556, respectively. However, the TRMM data underestimate the rain gauges data. The monthly correlation between TRMM data and the rain gauges data also indicates significant correlation (r > 0.5 significant at 95%), except during February when the correlation fall down the significant level (r = 0.1097). In general, the TRMM data can be used to replace the rain gauges data after taking into account the errors.
