Dear CF,
After attending the CF Workshop in Reading last month and presenting the
uncertainties standard we have come up with a different proposal. There
was concern with adding new reserved attributes instead of extending the
use of existing attributes. I've updated the proposal in a new Google
Doc
<
https://docs.google.com/document/d/1UR0flhrEE3yw_3dKW8NpCrGymLt9idwFXJBhZ5ngX3Y/edit?usp=sharing>.
Please feel free to comment or make suggestions to this new proposal.
If you don't want to read the short six pages here are the highlights:
* Uncertainties are written as a separate variable
* Will add three new standard name modifiers: total_uncertainty,
random_uncertainty, systematic_uncertainty
* Will deprecate current standard name modifier: standard_error
* Will add three new descriptors to cell_methods: standard_error,
confidence_interval, other_than_statistical_analysis (adding more is
an option)
* Will link the uncertainty variable to the data variable with
ancillary_variables (required)
* Will provide additional information with "references" variable
attribute (optional)
Thanks,
Ken
