Hello !

I think you need to rerun terrain with the option ltexture = true. After
that you can check that you have the texture fields ( needed by dust
emission) in your DOMAIN000.nc file.
Also you need to perform the chbc step to generate dust boundary
conditions if you want them, or set ichebdy=0 if you want to relax toward
zero concentration at the boundary ( in which case the chbc step is not
necessary).

Finally the rdtsemfac might also be adjusted.
Usually I use rdstemfac=1 (default)  when I use the new option
ichdustemd = 2 ( which I think is better at least over the sahara). With
the option ichdustemd =1 , the emission more intense and I remember using
a rdstemfac = 0.7 to get more realistic emissions. But again all of this
domain dependant ..
