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

Description

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).

21 Among regimes of the 50S-50N_CPR_set.Cld42+Prx7, some regimes having distinct precipitation characteristics can be predicted by precipitation information only (Jin et al. 2020, JAMC, submitted). This data is the projected regimes on the IMERG domain (30-minutely in 1degx1deg resolution). https://data.nasa.gov/docs/datasets/public/MODIS_t+a_cld+pr6x7_hist_50S-50N_CPR_projected2IMERGdomain.Cld42+Pr6x7.nc

21 Cloud-Precipitation Hybrid Regimes derived from MODIS C6.1 2D joint histogram of CTP and COT (total 42 bins) and IMERG v06B precipitation histogram (total 6 bins) in 50S-50N domain. This version sets the weight of precipitation as 3, so the total size of each vector is 60 (=42+6x3). It Includes centroid file and the map of assigned regime on each grid cell. https://data.nasa.gov/docs/datasets/public/MODIS_t+a_cld+pr6x3_hist_50S-50N_CPR_set.Cld42+Pr6x3.nc
