Precipitation identifiers for meteorological features combining global GPM-IMERG retrievals and ERA5 reanalysis

The data collection provides 0.25-deg., 6-hourly global
feature-precipitation categories from 2001 to 2019. The data is generated
by merging GPM-IMERG observational rainfall (V6 final version) and
atmospheric features identified by multiple object-based algorithms.
Classified precipitation identifiers include rainfall associated with
atmospheric rivers (AR), frontal systems (FT), low-pressure systems (LPS),
mesoscale convective systems (MCS), and their co-occurrences (overlapping
areas of features at a given time). In addition to algorithm-identified
features, precipitation contributed from deep convection, non-deep
convection, stratiform, and drizzle are pixel-wise defined using
thresholds of CPC MERGE-IR brightness temperature and GPM-IMERG rain rate.
The dataset is supported by the Department of Energy and Environment
(DOEE): DE-SC0023244.
