ABSTRACT

The availability of good rainfall data is a major factor in analyzing various phenomena related to rain. The rainfall data generated from the station is very accurate and reliable. However, it has various disadvantages such as incomplete data due to human error or measuring instruments, limitations in spatial resolution and availability in temporal scale. For this reason, there needs to be supporting rainfall data that can represent station data, especially in the Jambi area where good rainfall data is needed for various purposes. In this study validation of TRMM 3B42RT NASA and GSMAP JAXA satellite data on station observation data in Jambi. The method used is to compare the two satellite data with map making, graphs, and search for correlation values and RMSE to station data. After that, the best satellite data was selected to be compared with the data from 8 stations in Jambi to find out the distribution of data, graphics and the correlation and error values. From the study conducted, it was found that the rainfall value of the GSMAP JAXA satellite was closer to the station with a correlation value of 0.59 and an error of 98.75 mm/month. As for the comparison of GSMAP JAXA and data for 8 stations in the city of Jambi has a correlation range of 0.14-0.76 with an error value of 82.2- 172.27 mm/month.

Keywords: rainfall, station data, TRMM 3B42RT NASA, GSMAP JAXA.
