Abstract
This research was estimated the brightness temperature and find out how the surface temperature is occurring and its spread. In determining the estimation of temperature brightness using the Multi-Channel method. The results of this research are on data obtained from NASAs websites different from the data contained in the LAPAN website. The LAPAN data already has a brightness temperature value, while in NASA data there is only radians value. To find out using the Planck constant formula. Spatial results are the same between NASA data and LAPAN data. Data used from 15 – 16 July 2018 and 6 – 7 August 2019. The spatial results on channels 22 – 23 have a lot of contact between the basic surface, fog, sand storm, and smoke values. Whereas in the 31 – 32 channel, which can be known as the intersection of fog and clouds.
