Satellite Data Sources
Space-based emissions monitoring powered by advanced satellite technology
Floodlight leverages multiple satellite missions to provide comprehensive, top-down verification of greenhouse gas emissions. Explore the missions and instruments that enable our asset-level emissions intelligence.
Active Satellite Missions
6 missions currently integrated into the Floodlight platform
Filter by Pollutant
Showing 6 of 6 missions
GOSAT
Pollutant Types
Spatial Resolution
10.5 km diameter footprint
Temporal Resolution
3-day repeat cycle
Floodlight Usage
GOSAT (Greenhouse Gases Observing Satellite) is the world's first dedicated GHG satellite, measuring column-averaged CO2 and CH4 across the globe. Its long data record (2009-present) makes it valuable for trend analysis and multi-year baseline construction in Floodlight's methodology.
GOSAT-2
Pollutant Types
Spatial Resolution
9.7 km diameter footprint
Temporal Resolution
6-day repeat cycle
Floodlight Usage
GOSAT-2 is the successor to GOSAT, launched in 2018, with improved sensitivity and an additional CO retrieval capability. Its enhanced signal-to-noise ratio improves detection of CO2 and CH4 point sources, augmenting Floodlight's multi-sensor ensemble for high-confidence emission assessments.

GOSAT-GW
Pollutant Types
Spatial Resolution
~910 km swath; 1-10 km cell
Temporal Resolution
6-day repeat cycle
Floodlight Usage
Launched in 2025, GOSAT-GW (IBUKI-GW) extends the GOSAT lineage with a much wider swath that closes coverage gaps between polar overpasses. Carrying the TANSO-3 instrument, it adds NO2 to the GHG menu and dramatically improves Floodlight's ability to resolve emissions over partially clouded scenes and at higher latitudes.

OCO-2
Pollutant Types
Spatial Resolution
1.29 km x 2.25 km
Temporal Resolution
16-day repeat cycle
Floodlight Usage
OCO-2 (Orbiting Carbon Observatory 2) provides high-resolution measurements of atmospheric CO2 globally. Floodlight uses OCO-2 retrievals to cross-validate facility-level emission estimates and to characterise regional CO2 background concentrations for atmospheric back-projection.
OCO-3
Pollutant Types
Spatial Resolution
1.6 km x 2.2 km
Temporal Resolution
Non-sun-synchronous; ISS orbit
Floodlight Usage
OCO-3 operates from the International Space Station, allowing observations at varying local solar times unlike polar-orbiting satellites. This makes it uniquely suited for studying diurnal emission cycles at industrial facilities, complementing OCO-2's fixed overpass timing in Floodlight's temporal analysis.

Sentinel-5P TROPOMI
Pollutant Types
Spatial Resolution
5.5 km x 3.5 km
Temporal Resolution
Daily global coverage
Floodlight Usage
The TROPOMI instrument aboard Sentinel-5P provides daily global coverage of multiple trace gases at the highest spatial resolution of any currently operational atmospheric composition satellite. Floodlight relies heavily on TROPOMI CH4 and NO2 columns for asset-level methane and NOx emission detection and quantification.
Note: Floodlight continuously evaluates new satellite missions and instruments to enhance our emissions monitoring capabilities. This list represents actively integrated data sources as of the current platform version.
