In the macro first we call flexpart_total_column() to compute the "tcmd" fields with units of "kg m**-2".

Next, we define the contouring. The "tcmd" fields are automatically scaled into "ng have the units of "kg m**-2" for contouring (see here for details) but with the current value range it is better to use "g m**-2" units would better fit for contouring. To achieve it we simply multiply the "tcmd" fieldset with 1000:
