Abstract of seminar:
Accelerated increases in concentrations of anthropogenic greenhouse gases (GHGs: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)) are the well-known primary driver of climate change. Besides, short-lived climate forcers (SLCFs) such as ozone (O3) and aerosols are also important - the assessment of residual carbon budget and the development of climate mitigation policies need to integrally take into account these substances. In this seminar, we will first discuss the roles and contribution of the Japanese GOSAT satellite series in understanding the changes in GHGs as well as their future prospects. They include 1) advanced assessment of GHGs inventories and international collaboration, 2) contributions to Global Stocktake, 3) prospect with GOSAT-GW observations measuring NO2 as a SLCF, and 4) a follow-on mission currently under discussion. Studying SLCFs together is important to refine GHG flux estimations and also to better estimate future changes in the lifetime of CH4. In addition, aspects of SLCFs reduction that generate benefits to human and plant health, i.e., co-benefits with climate change measures, are to be highlighted; sustainable development will also be discussed in this context.
