GHGSat vs MethaneSAT vs TROPOMI: satellite emissions monitoring platforms compared
Compares three leading satellite methane monitoring systems: GHGSat (25 m resolution, facility-level targeting, commercial), MethaneSAT (100 m × 400 m, basin-wide mapping, open data), and TROPOMI on Sentinel-5P (7 km, global daily coverage, free). Evaluates detection thresholds from 100 kg/hr to 10,000 kg/hr, data latency, and MRV certification suitability.
