Re: [CF-metadata] Question from NODC about interplay of standard name modifiers, cell_methods, etc.

2013-04-02 Thread Cameron-smith, Philip
Hi Steve, I think your suggestion has merit. One question is : Would your suggestion make any other changes, eg to std_name modifiers or cell_methods? If nothing else, it would be good to put something in the CF documentation that explains what is going on, and why (perhaps along the lines of

Dear All, I am currently working on a Trac ticket submission for handling of taxonomic data in CF and thought I'd run an example past the list to make sure I've got it right. Jonathan suggested using a container variable analogous to geographic regions. My interpretation of this would result

Steve, I'd say we have a problem. I think your first-cut solution is probably too minimalist, but it would be better than the current situation. Grace and peace, Jim Jim Biard Research Scholar Cooperative Institute for Climate and Satellites Remote Sensing and Applications Division National C

2013-04-02 Thread Jonathan Gregory
Dear Roy Yes, I think you are right that it is useful to have the taxon as a dimension because it allows you to put several of them in one variable, provided it's the same quantity, with the same generic standard name. That is just like bundling up timeseries from different locations into one data

Dear all Jim asked, "As some examples of the confusing situation we have now, why do we have a separate word modifier number_of_observations instead of a number_of_observations_of_X transformation modifier? Why don't we have variance_of_X or anomaly_of_X transformations (or separate word modifie

Hello Jonathan, The reason that I used MAXT rather than TIME is that I am trying to follow the point data conventions with the possibility of multiple time series (along the INSTANCE dimension) of different lengths stored as padded rather than ragged arrays in a single file. Your example is re

Jonathan, You haven't been unclear about how we got into the state we are currently in. We got to now by adding bits here and there as needs arose without always thinking about the implications for the whole system down the road (which you did a great job of describing). A lot of good work ha
