How To Access Data

Project Proposal (Restrained)

Go to the ESA User Services Portal
Register or log in to EO Sign In
After logging in, complete and submit the form with your proposed use of the data
The proposal will be evaluated by ESA, which normally takes between 4 and 6 weeks
Upon successful evaluation, you will receive a confirmation email, which describes the amount of data to be provided, and details of how to order the data

Description

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
