ECLAC presents the Greenhouse Gas (GHG) Satellite Monitoring System to measure the trend in concentrations in Latin American countries

The Economic Commission for Latin America and the Caribbean (ECLAC) makes available the Satellite Monitoring System for Greenhouse Gases (GHG)free access web portal whose objective is “facilitate coherence and ambition between policies and results, by being able to count on real-time information” on trends in GHG concentrations and CO emissions₂.

The System allows to know the trends in the concentration of GHG and the flows of CO₂ of the Latin American countriesits main cities and subregions and has been developed by ECLAC’s Division for Sustainable Development and Human Settlements with the support of the Center for Mathematical Modeling of the University of Chile (CMM) funded by the EUROCLIMA Program.

The System operates with information provided by Low Orbit Earth Observation Satellites (LEOs), which allows monitoring those gases regulated by the United Nations Framework Convention on Climate Change: Carbon Dioxide (CO2), Methane (CH4) and Nitrogen Dioxide (NO2). But it also monitors six other polluting gases in the atmosphere: Total Ozone (O3), Tropospheric Ozone (O3), Aerosols (AI), Sulfur Dioxide (SO 2), Carbon Monoxide (CO) and Formaldehydes (HCHO).

The portal allows requesting a report by selected gas, city, country, or for the Latin American regions of interest to users, also allowing filtering by a range of dates. All this information can be downloaded in PDF format or the point file (raster) to be entered into the GIS application (ArcGIS, QGIS, etc.), in GeoTIFF format.

This system is an input that allows States to “compare the results of climate policy and action with changes in the trajectories of CO2 emissions, and of policies to mitigate pollution from other gases and particles of local interest, over the territory”. Those interested can access the CO2 Emissions Monitoring System here and to the Concentration Monitoring System of Greenhouse Gases, and other gases and particles, here.
