Hi everyone!

I am using ERA40 data with RegCM3, version released in Feb' 05. I am trying to do land use experiment. I [erformed the following steps;

1- I ran the model for perticular dates and domain.

2- Then I modified .../Preproc/Terrain/LANDUSE file

3- and ran the icbc.x script then compiled and again ran the model with new icbc for the same dates and domain.

But when I compared two different output fields, it gave zero difference.

Why did it happened so? Should I follow some steps other  than  mentioned above?

can you please help fix this problem
