What happened? What did you expect to happen?

USTAR is one of the most significant variables used in DustDead dust emission. Currently, DustDead is calculating its own friction velocity WND_FRC from reference wind at 10m with a reference roughness length. https://github.com/geoschem/HEMCO/blob/3bd40ad84c46c36107d83b5353e57ce279b593f0/src/Extensions/hcox_dustdead_mod.F#L1482-L1497 https://github.com/geoschem/HEMCO/blob/3bd40ad84c46c36107d83b5353e57ce279b593f0/src/Extensions/hcox_dustdead_mod.F#L2707-L2709 USTAR and Z0 read from meteorology is only read but ignored in following calculation. https://github.com/geoschem/HEMCO/blob/3bd40ad84c46c36107d83b5353e57ce279b593f0/src/Extensions/hcox_dustdead_mod.F#L1467-L1480 Is there any historical reason for not using USTAR directly from GMAO, or is it just a bug?
