Dear RegCNET,

In the past few months I was working on RegCM4.0 before the newer version came out. And I realized that the aerosol tracer output trac2 for Dust of size 1.0 to 2.5 um is set to a constant zero (image output from GrADS attached). Is this a one time problem? or has this problem arisen before? Is there a solution?

Regards,

James
