The surface concentration unit is not right

[hawklorry]

The surface concentration is g/m2 but the system treats it as kg/m2. I have run a simulation and it shows the surface concentration is about 0.4 g/m^2. However, the downloaded shapefile shows it's about 0.0004 g/m^2 (second screenshot). The third screenshot shows the content of the netcdf file. It shows the surface concentration is in g m-2 and quite small.
