![]() This forcing drives the ERA5-Land single simulation and it has been obtained by assimilating observations through a 4D-VAR data assimilation system and a Simplified Extended Kalman FilterĪlso ozone, aircraft and surface pressure data ![]() Observations indirectly influence the simulation through the atmospheric forcing from ERA5.
