Grib Interpolation Regular Resolution
Sets the plotting resolution, in degrees, of GRIB fields encoded in space_view projection. The default is 0.1.
Grib Scaling of Retrieved Fields
Toggles the scaling of the retrieved fields On /Off. Fields which are retrieved from MARS or derived from other fields are in SI units. If this parameter is On, MAGICS will perform a unit conversion (scaling) on the retrieved fields that it plots, converting from these SI units to units of customary meteorological usage - e.g. Pressure from Pa to hPa/mb, Temperature from K to °C.
Grib Scaling of Derived Fields
Toggles the scaling of the derived fields On /Off . Any field you derive is in SI units, so set this parameter to On to convert to meteorological style units. E.g. :
- If you retrieve two temperature fields, they are plotted in °C . If you derive a mean temperature from them, it will be plotted in K if you do not scale the derived field.
- Precipitation fields are cumulative fields plotted in mm - if you subtract two consecutive ones to obtain the precipitation for the time step between them, you will plot a field in m if you do not scale the derived field.
