GPM IMERG
Integrated Multi-satellitE Retrievals for GPM
NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) algorithm combines information from the GPM satellite constellation
to estimate precipitation over the majority of the Earth's surface. IMERG is particularly valuable over areas of Earth's surface
that lack ground-based precipitation-measuring instruments, including oceans and remote areas.

ERA5
ECMWF Reanalysis v5
Reanalysis combines model data with observations from across the world into a globally complete and consistent dataset using the laws of physics.
This principle, called data assimilation, is based on the method used by numerical weather prediction centres, where every so many hours

CHIRPS
The Climate Hazards group Infrared Precipitation with Stations
Climate Hazards Center InfraRed Precipitation with Station data (CHIRPS) is a 30+ year quasi-global rainfall dataset. CHIRPS incorporates 0.05° resolution satellite imagery
with in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.
Years: 1981 to present
Resolution: 0.05° x 0.05° (or roughly 5km x 5km)
Coverage: Global
SILO
SILO climate data
SILO is a database of Australian climate data from 1889 to the present. It provides daily meteorological datasets for a range of climate variables in ready-to-use formats suitable for biophysical modelling, research and climate applications.
SILO uses mathematical interpolation techniques to construct spatial grids and infill gaps in time series datasets. Users are advised to understand the implications and accuracy of using interpolated data. Scientific papers on SILO are available.
Gridded daily climate surfaces which have been derived either by splining or kriging the observational data.
Data at station locations consists of observational records which have been supplemented by interpolated estimates when observed data are missing.
Years: 1889 to present
Resolution: 0.05° x 0.05° (or roughly 5km x 5km)
Coverage: Australia only
