Abstract

Rainfall data analysis from three types of sensors installed on Maritime Meteorology Station owned by Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG’s) in Pontianak has been carried out. The three types of sensors were Observatory (OBS), Hellman, and Tipping Bucket (TB). This research used analysis of variance (ANOVA) and correlation tests because although calibrations to the rainfall sensors are performed every year, their measurement results are still different.Comparison results showed that there were no significant differences among them, while correlation tests revealed that there were strong correlations between the measurement results of OBS and Hellman (0.9457), OBS and TB (0.9869), and Hellman and TB (0.9651).
