Worldwide PhenoCam EFAST feasibility screening

Screen the global PhenoCam Network for sites where EFAST Sentinel-2 / Sentinel-3 fusion is likely to work: enough PhenoCam gcc_90, seasonal signal, and S2/S3 coverage for a calendar year.

Agent-oriented detail: AGENTS.md.

Quick start

From processing/:

uv sync
uv run python 1-phenocam.py --evaluation-year 2025

Stepped pipeline (resumable)

All steps use --evaluation-year (default 2025) and optional --site. See each script docstring for inputs/outputs under data/.

uv run python 1-phenocam.py --evaluation-year 2025
uv run python 2-phenocam-screening.py --evaluation-year 2025
uv run python 3-sentinel-data.py --evaluation-year 2025
uv run python 4-fusion.py --evaluation-year 2025
uv run python 5-metrics.py --evaluation-year 2025

# single site
uv run python 3-sentinel-data.py --evaluation-year 2025 --site innsbruck
uv run python 4-fusion.py --evaluation-year 2025 --site innsbruck
uv run python 5-metrics.py --evaluation-year 2025 --site innsbruck

Step 3 S3 uses CDSE OpenEO (SENTINEL3_SYN_L2_SYN); S2 uses AWS Earth Search COG range reads (no auth).

Outputs (under data/)

Artifact	Step	Role
phenocam/{year}.json	1	Site list + sites_dir pointer
phenocam/{year}/{site}.json, {site}_1day.csv	1	Raw API + GCC CSV
phenocam_screening/{year}.json / .csv	2	PhenoCam + SNR gate results
sentinel_data/{year}/{site}/prepared/s2/	3	S2 REFL + DIST_CLOUD GeoTIFFs
sentinel_data/{year}/{site}/prepared/s3/	3	S3 composite GeoTIFFs
fusion/{year}/{site}/	4	BtI/ItB fused rasters
metrics/{year}/{site}/, metrics/manifest.json	5	Timeseries JSON, covariates, webapp manifest

The 2025 manifest currently lists 739 cameras with archive overlap; most per-site CSV/JSON files are cached under data/phenocam/2025/.
