Dear Jonathan:
(1) Note that there are no quantities in the standard name table with units of degrees celsius.. (2) Also note that I took a look at udunits 2 and degC is not in the XML... - < unit > < def > K @ 273.15</ def > - < name > < singular > degree_Celsius</ singular > < plural > degrees_Celsius</ plural > </ name > < symbol > °C</ symbol > - <!-- DEGREE SIGN --> </ unit > Am I missing something regarding how to interpret and use udunits2? very respectfully, randy ---------------------------------------- From: "Jonathan Gregory" <[email protected]> Sent: Monday, June 10, 2013 5:27 PM To: [email protected] Subject: Re: [CF-metadata] new standard name: atmosphere_stability_k_index Dear Jonathan K and degC have the same dimensions and either is acceptable, I would say.
