Data

GHGSat DOWNLOAD Dataset available upon positive evaluation of Project Proposal (usually 2 weeks).

blue arrow DESCRIPTION

The GHGSat-C1 and GHGSat-C2 satellites capture with very high spatial and spectral resolution the greenhouse gas emissions and measures the vertical column densities of atmospheric gases through its hyperspectral imaging spectrometer operating in a narrow band of the short-wave infrared (SWIR) region of the electromagnetic spectrum. Both archive and new tasking data can be requested, based on a single observation of the scene, as well as the full year product which is the average annual emission rate based on as many observations as can be successfully collected.

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

blue arrow HOW TO ACCESS THIS DATA

The collection is open for research and application development, prototype and test projects to users located in the territory of ESA Member States (including Canada), in the European Commission Member States and in China as part of the Dragon cooperation programme but GHGSat can introduce limitation 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.

As GHGSat is a '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).
