Hello,

I'm seeking information on the RUC visibility product. According to your web site, visibility is calculated using
a modified version of the Stoelinga-Warner algorithm along with a "home-grown" relative humidity-based parameterization. Is there a document available that lists the equations used? I already have the original Stoelinga-Warner paper, but that doesn't discuss graupel or RH.

Thanks,
