How to Access Data

The collection is open for research and application development, prototype and test projects to worldwide users but GHGSat can introduce limitations to users located in countries that are under Government of Canada sanction.

Data are available to order on demand upon submission of a Project Proposal subject to evaluation and acceptance by ESA and the data owner.

The process takes up to two weeks and there are no deadlines for submitting a proposal.

As GHGSat is a 'Third Party Mission (TPM) under assessment', it is necessary to submit a full report to ESA in order to gain access to the data. Access is granted following an evaluation to determine the suitability of the request. (ESA GHGsat Final report template).

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be allowed to each project.

Availability and restrictions to the use of the data are described in the ESA Third Party Missions (TPM) T&C document and in the Terms of Applicability document


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
