Description

PARDIG (Precipitation AI Reanalysis - Densely Inferred GPM) is an experimental dataset of global AI-driven precipitation estimates by Google DeepMind and Google Research, produced by the model described in: Global Precipitation Estimates Learned from Sparse Satellite Observations.

PARDIG is produced by an AI model that is trained to predict precipitation estimates from the Combined Radar-Radiometer Algorithm (CORRA), part of the NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory. PARDIG-LR relies on ECMWF's ERA5, NOAA's GridSat-B1, and a global mosaic of polar-orbiting (LEO) microwave sounder observations as its inputs. PARDIG precipitation estimates are provided at a 15 minute cadence and 0.1° spatial resolution.

This image collection provides the full historical archive of PARDIG-LR (Long-Record) from 1999 through 2023. The dataset is also available in Zarr format in our Google Cloud Storage bucket (gs://pardig_1/LR/). The companion dataset, PARDIG-NRT (Near-Real-Time), is also available on Earth Engine and on Google Cloud Storage (gs://pardig_1/NRT/).

Both datasets are publicly available in the Earth Engine Data Catalog and on Google Cloud Storage. Users can access them via their Google Cloud account immediately, without needing to explicitly apply for access.
