Global Greenhouse Gas Watch in support of transparency

Global Greenhouse Gas Watch will provide a valuable tool to support the transparency of global mitigation action. The system will be built on three components: an integrated global observing system, global modelling with data assimilation and international data exchange. Open and unrestricted access to data will ensure a full transparency of system outputs. The ultimate goal is to produce a global distribution of monthly fluxes for CO₂, CH₄ and N₂O with 100x100 km resolution. The quality of the outputs will be ensured through the participation of several modelling centers. The observing network will build on the existing efforts of WMO and IOC UNESCO, while the design and gap-filling in support of the GGGW will be done in a more systematic way. The outputs will provide globally consistent information that will feed multiple applications including supplementary information to the traditional inventory reporting. Unlike traditional inventory, GGGW will take into account climate feedback in the carbon cycle in the net flux estimates.
