GHGSat DATA.SAT Methane Emissions Data

GHGSat DATA.SAT delivers satellite-derived methane emissions data to industrial operators, regulators, and environmental compliance teams. The service draws on the GHGSat commercial constellation, which observes point-source methane emitters (oil and gas facilities, landfills, coal mines, and agricultural sites) at reported spatial resolutions of approximately 25 m (ESA Earth Online^[1]) or approximately 30 m for C-series satellites (eoPortal^[2]). The earlier GHGSat-D prototype exceeded 50 m; current commercial service uses the C-series specification.

Data are delivered as quantified emission rate estimates, not raw radiance. Buyers receive attributed point-source flux measurements tied to individual facility sites. NASA Earthdata CSDA documentation describes a 48-hour delivery latency as part of its access arrangement^[3]; whether 48-hour turnaround is the standard commercial tier has not been confirmed from operator documentation as of 2026-05-31.

The primary commercial service covers methane (CH4). GHGSat launched a CO2 sensor on its C10/Vanguard satellite, noted as the first commercial CO2 sensor in orbit^[4]. Whether CO2 data is available as a named commercial service tier via DATA.SAT, rather than as a research or pilot programme, had not been confirmed from operator product documentation as of 2026-05-31.

Access is operator-direct; contact GHGSat for pricing and licensing terms. The service is offered alongside DATA.GROUND (ground-based sensor network) and DATA.AIR (airborne) under the GHGSat DATA product family^[5].
