RE: How to interpret Dominant Soil Category plot

This post was from a previous version of the WRF&MPAS-A Support Forum. New replies have been disabled and if you have follow up questions related to this post, then please start a new thread from the forum home page.


I have plotted the dominant soil categories from the input static data and I need information as to how I can interpret the color and scale.

I am using input static data from 30-arc-second USGS GMTED2010 (Topography), MODIS FPAR (GreenFrac) and 21-class MODIS (LU_Index/Landuse).

Please see attached the plot of the dominant soil categories.

Appreciate your assistance and advice.

You can find a table of soil categories in Chapter 3 of the ARW User's Guide that relates the soil category indices to soil types. Since this is an integer-valued field, you may like to adjust the contour values on your plot so that the increment between contours is 1.0.
