Space data help to unravel the complexities of Earth’s atmosphere
As the impacts of the climate crisis intensify, scientists are using ESA’s Earth observation archives to investigate atmospheric processes and their influences on the planet’s changing environment.
News - Data Release news
GHGSat data now available through ESA's Earthnet programme
In the framework of the Earthnet programme, ESA is offering, for scientific research and application development, access to archive and new tasking data from the GHGSat mission.
Mission - Third Party Missions
The GHGSat mission is dedicated to measuring emissions of greenhouse gases.
Data - Data Description
GHGSat archive and tasking
The following products are made available: Abundance dataset (Level 2): Set of per-pixel abundances (ppb or mol/m2) for a single species, and per-pixel measurement error expressed as a standard deviation for a single site on a single satellite pass. Data format is GeoTIFF (16-bit) or optionally GeoTIFF (32-bit or 64-bit floating point) Concentration Maps (Level 2): High readability pseudocolour map combining surface reflectance, and column density expressed in ppb or mol/m2 for a single species in PNG (optional PDF) format. The relevant abundance dataset is provided as well. Emission Rates (Level 4): Instantaneous emission rate from targeted source estimated using abundance datasets from a single satellite pass and applying dispersion modelling techniques in PDF format. The delivered product includes the emission rate estimate with uncertainty and key dispersion parameters (in CSV format) as well as the abundance dataset used for the emission estimate. The properties of available products are summarised in the table Band(s) / Beam Mode(s) and Polarisation SWIR (1635-1675 nm), multiple bands, unpolarised Spatial Resolution <30 m Scene size 12 km x 12 km Species Measured CH4 Geometric Corrections Radial distortion, perspective projection Radiometric Corrections Detector pixel response, ghosting, spectral response, atmospheric correction including trace gas modelling and surface reflectance Details about the data provision, data access conditions and quota assignment procedure are described in the GHGSat Terms of Applicability.
