Abstract
The progress of the CO2 Human Emission project in the first year has been presented illustrating the first CHE global nature runs covering the year 2015 at 9km and 3-hourly resolutions, along with the agenda for the development of a monitoring support system for CO2 anthropogenic emissions. The CO2 fits well within GCOS scope and aims and is one of the 7 Global Climate Indicators and 54 Essential Climate Variables. Both the terrestrial natural biosphere exchanges of CO2 and the fossil fuel emissions require adequate observing systems and the combined used of satellite and in-situ observations.
