Sentinel-1 C-band radar activity maps

Daily maps, each covering 28 days, of C-band (5.4 GHz) interference reported in the Copernicus Sentinel-1 radar's own RFI annotation, made by tools/s1_rfi_global.py and tools/s1_daily.py: per H3 res-3 cell, the share of passes with RFI. Mostly radars; not GPS interference; regions, not sites. Aggregates only. Contains modified Copernicus Sentinel data 2026. Method: docs/validation/s1-rfi.md.

GNSS degradation data, 2026-11

GNSS degradation outputs for 2026-11, one set per UTC day, made automatically by the daily workflow
(.github/workflows/daily.yml) from the adsb.lol globe_history archive. Not reviewed by a person.

Licence: ODbL 1.0, derived from adsb.lol. Aggregates per H3 hex and region only: no aircraft identifiers.

Per day: <day>.parquet (per hex), .hourly.parquet, .minute.parquet, .summary.json (run details and method
parameters), .sbas.json, .anomalies.json, .bursts.json, .hotspots.json (shares in the named areas) and
.map.json (the site's map file).
Method: method card.

SMAP 1400-1427 MHz interference maps

Daily maps, each covering 7 days, of interference flagged in 1400-1427 MHz by NASA SMAP's radiometer, made by tools/smap_rfi.py and tools/smap_daily.py: single emitters standing out of a quiet background (sources) and crowded regions (busy). Aggregates only. Source: SMAP L1C Radiometer Half-Orbit 36 km EASE-Grid Brightness Temperatures, Version 6. NASA NSIDC DAAC. doi:10.5067/DV7IX2DQ681Y.

Sentinel-6A receiver daily maps

Daily maps of GPS interference heard by Sentinel-6A's own GNSS receiver, by region (H3 res 2), made by tools/s6_rfi.py and tools/s6_daily.py. Aggregates only.

Contains modified Copernicus Sentinel data 2026; Sentinel-6A GNSS-RO-POD tracking data, PO.DAAC (doi:10.5067/S6AGN-1ROPD); Orbital data: USSPACECOM (space-track.org); Broadcast navigation: IGS.

COSMIC-2 receiver daily maps

Daily maps of GPS interference heard by the COSMIC-2 satellites' navigation antennas (UCAR's per-antenna RFI index), by region (H3 res 2), made by tools/cosmic2_rfi.py and tools/cosmic2_daily.py. Aggregates only. Method and validation: docs/validation/space-receivers.md. COSMIC-2 data: UCAR COSMIC Program (CDAAC), near-real-time level 1b podTc2 (CC BY 4.0).

NISAR L-band emitter sites (daily)

Daily public export of repeat L-band emitter sites seen in NASA-ISRO NISAR radar data (the RSLC processor's own RFI tables), made by nisar/nisar_rfi/public.py. Leads, not attribution.

CYGNSS daily summaries

Daily summaries of GNSS L1 interference seen from orbit by NASA CYGNSS (noise floor of the delay-Doppler maps), made by tools/cygnss_rfi.py and tools/cygnss_daily.py. Aggregates only. Source: NASA CYGNSS Level 1 Science Data Record V3.2 (PO.DAAC, doi:10.5067/CYGNS-L1X32), NASA open data. Method and validation: docs/validation/cygnss.md.
