Introducing Φ-Down: a practical gateway to Copernicus EO data
Accessing Copernicus data should not require wrestling with fragmented APIs and brittle download scripts. Φ-Down is a Python library designed to simplify, standardize, and accelerate the search and download of Earth Observation data from the Copernicus Data Space Ecosystem.
What Φ-Down offers
-
Unified search across Sentinel missions and contributing datasets
-
Advanced filtering (AOI, time, orbit, cloud cover, burst-level SAR)
-
Direct, efficient downloads via S3
-
Native support for Sentinel-1 SLC burst mode (InSAR-ready)
-
Python API and CLI for reproducible workflows
Φ-Down is built for researchers and developers who want control, performance, and clarity, without re-implementing low-level plumbing.
Install: pip install phidown
