earthlens is a Python package for downloading satellite and climate data from multiple sources, including CHIRPS rainfall (FTP), ERA5 on AWS S3, the ECMWF Climate Data Store via cdsapi, and Google Earth Engine. It provides a unified EarthLens facade that lazily loads each backend so the optional SDK for a backend you don't use never has to be installed.

Optional backends can be enabled by additionally installing:

• boto3 (for the ERA5-on-S3 backend)
• cdsapi (for the ECMWF/CDS backend)
• earthengine-api (for the Google Earth Engine backend)
