Hi all, I think Steve has got to the heart of the issue with his comment, IMHO it is the client libraries that hold the answer to this question. However you choose to peer into your netCDF files you are seeing them through the lens of a client library. And it's worth noting that date/times

Re: [CF-metadata] Ancillary Data

Hello Jim you present an interesting case, thank you I can see how I can relate energy deposited(x,y,z,t) to an ancillary variable of model atmosphere density profile(x,y,z) In this case, for any value in my energy deposited data array I can retrieve an appropriate value for my

Re: [CF-metadata] Ancillary Data

2013-03-15 Thread Jim Biard
Mark, I'm looking at this from the standpoint of the use of an ancillary variable to provide metadata about the individual values of another data variable. The way I think of it, the atmosphere profile used to produce a given energy deposited value falls under the category of metadata for the

Re: [CF-metadata] standard names for ocean model turbulent quantities

Dear Allison, Thank you for your comments. I'd propose some further changes to the definitions: 1. specific_turbulent_kinetic_energy_of_sea_water (m2 s-2) As turbulent kinetic energy is not necessary equivalent to model's subgrid scale eddy kinetic energy, I'd formulate the definition as: '

Hi All: Ok, its friday afternoon so ill bite on this, and wax philosophical even before the beer. An insidious mistake is to think that problems should be fixed in software libraries. Actually the deep mistake is to mistake the reference software with the file encoding. Why bother fixing

Re: [CF-metadata] how to specify time dimension for monthly averages

2013-03-15 Thread Seth McGinnis
1) Set the time values to the midpoint of the time interval.* 2) Set a cell_methods attribute on the data variable with a value of time: mean (interval: 1 month). 3) Create a time_bounds variable with dimensions (time,2) whose values are the start and end points of each time interval. 4) Set
