Thank you! I will take a little time to work on the input I have recieved, and post back what I have done, possibly along with a suggestion for some new standard names.

But this raises some other issues: > 2) probability that air temperature will be within 2.5 degrees of the forecast This is clearly trying to get at something akin to what we do with the "standard_error" standard name modifier and the "standard_error_multiplier" ancillary variable. The differences are that the units are flipped and the assumption of a normal distribution is removed. Can we use something analogous? Maybe a new standard name modifier like "distribution" or "probability" or "confidence" which requires an ancillary variable? The best fit for this particular case is "confidence" with an ancillary variable "confidence_interval" with value 2.5. But something more like "distribution" is more general and could be stretched to handle > 1) "25th percentile precipitation amount" (based on ensemble data) Here we might use the "distribution" (or "cumulative_distribution"?) standard name modifier, ancillary variable "cumulative_probability", value 0.25. -- Evan _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
