All that is required for an assembly to run on a non-Windows platform is for the CLR to be ported to that platform.Resources include such things as string tables, cursors, and images. These can be stored either in an assembly or in a .resources file.In addition to language-neutrality ...
In this work, we present the development of a 4D-Ensemble-Variational (4DEnVar) data assimilation technique to estimate NOx top-down emissions using the regional chemical transport model LOTOS-EUROS with the NO2 observations from the TROPOspheric Monitor
