It's just been pointed out to me that the standard unit for radar reflectivity is "dBZ", which is included in the current release of udunits. It is defined there as equal to "0.1 lg(re (1e-6 m)^3)", so the reference level is included in the definition. --Russ _______________________________________________ CF-metadata mailing list CF-metadata@cgd.ucar.edu http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
