MODIS Cloud Regimes and Cloud-Precipitation Hybrid Regimes (MODIS-IMERG)

Published by Daeho Jin | National Aeronautics and Space Administration | Metadata Last Checked: August 04, 2025 | Last Modified: 2025-04-23
Cloud regimes and Cloud-Precipitation Hybrid Regimes are derived via k-means clustering, with MODIS C6.1 2D joint histogram of CTP and COT (total 42 bins) and IMERG v06B precipitation histogram (total 6 bins) in 50S-50N and 15S-15N domain. By the relative weight between cloud and precipitation, there are 4 kinds of regime sets for each tropical and extended domain: 1) Cloud only (42 bins), 2) Cloud+Precipitation with weight 1 (Cld42+Pr6x1; 48 bins), 3) Cloud+Precipitation with weight 3 (Cld42+Pr6x3; 60 bins), 4) Cloud+Precipitation with weight 7 (Cld42+Pr6x7; 84 bins; equal weight).
