I have placed our ARM cloud fraction analysis from 1997-2003 at ftp://ftp.met.utah.edu/pub/mace/Cloud_Fraction in graphical and digital (netcdf and ascii) form along with a README file.  The files can be accessed via anonymous login with email as password.  The posted information should allow a satellite analyst to validate cloud occurrence/fraction with ground-based radar statistics over Oklahoma. If there is any interest in doing this, we could extend this time series to other sites and to more current times at SGP.
