The need for country masks for future national greenhouse gas flux estimations

• The Paris Agreement requests a substantial reduction of greenhouse gas (GHG) emissions. These emissions are currently mainly estimated from bottom-up inventories and process-based models of land and ocean fluxes. Another, complementary approach is based on measurements of the atmospheric GHG concentration in combination with atmospheric inverse modelling to provide the GHG fluxes. For the latter approach the GIScience community should contribute with providing an appropriate country mask to enable estimations of national budgets. This paper aims at describing the requirement of such a country mask as well as report on technical solutions for preliminary tests we made on national GHG flux estimations.
