Re: [CF-metadata] Meeting invite: Advancing netCDF-CF, 24-26 May 2016, Boulder, CO, USA

Ethan:

I would very much appreciate participating remotely when the discussions of space weather products came up.

I am already a member of cf_satellite so no issue.

The problem with my tech memo is there is SO MUCH THERE. Discussions on the message board usually attack one “construct” at a time. It will be overwhelming without an overarching introduction (which I would be glad to do).

Note that I have had a quick email exchange with W. Kent Tobiska ("W. Kent Tobiska" <[email protected]>) who is a top authority on space weather in general, but I don’t think he is plugged into netCDF/cf. I think he has been laying the groundwork/foundation for many types of level 2 and level 3 space weather products and using ISO as a means to standardize. The ASCII product files that his efforts generate are self-describing, but they are not done in a standards-based way like CF requires, and he is not using netCDF. I have attached an ISO working draft of the kind of work he is doing. I suspect it would be a formidable activity to get everybody on the same page.

I wish I could spend more time on it, but I have got to pay the bills.

Thanks !

Hi Randy,

Sorry you won't be able to join us in May.

Thanks for the GOES-R / CF document! I'm sure it will be a good resource in discussions about CF and satellite data. The project folks focused on satellite data are planning to use the existing [email protected] email list [1] to make sure the broader community can easily get involved in that conversation.

Also, we will have some form of remote participation available. Let me know if you want to participate in any parts of the meeting that way.

Cheers,

Ethan

RE:
Adding features to better support satellite data

See attached white paper for how to extend CF conventions for GOES-R level 1b space weather data. These conventions will work for polar orbiting satellite level 1b space weather data also. Level 2 space weather products ill require additional constructs,

Business has been lousy. Otherwise, I would love to come !

very respectfully,

randy

Hi all,

As some of you have heard, we are holding a meeting to discuss current and future netCDF-CF efforts and directions. The meeting will be held on 24-26 May 2016 in Boulder, CO, USA at the UCAR Center Green facility.

This meeting is organized by the “Advancing netCDF-CF for Geoscience” project [1] which has been funded by the US NSF EarthCube program. The project goals include several specific CF development efforts, both standards development and software prototyping. (We are just starting to spin-up community conversations around these specific goals for drafting CF extensions.) Another aspect of the funded project is community engagement including with the existing CF community, geoscience domains that have not been very involved in CF, and other standards bodies (e.g., OGC). These and other topics are on the current list of possible agenda items. Please let us know if you have other agenda items in mind.

The current list of possible agenda items includes:
Investigate using features of the netCDF enhanced data model to improve/simplify the CF Discrete Sampling Geometries (which includes point, sounding, and trajectory data types)
Drafting a CF enhancement that would add support for complex data footprints (e.g., river segments and drainage basins)
Further develop the CFRadial proposal for representing Radar data
Adding features to better support satellite data
Adding CF support for hierarchical groups for organizing data and metadata
Enhancing CF to support Linked Data / semantic technology concepts
Harmonizing CF grid mapping with OGC CRS (coordinate reference systems), possibly with WKT
Adding CF support for attribute namespaces and the use of URI prefixes in attribute values
Improved support for dimensionless data variables, logarithmic scales, differences, etc.
While we wish we could host all those interested in attending, given the available meeting space and the number of project participants, we are asking members of the CF community that are interested in attending to contact us directly and let us know which aspects of CF are of interest to you and your goals for the meeting. Please submit your expressions of interest by Monday, 4 April 2016. We plan to invite participants by Friday, 8 April 2016.

Travel and other information will be on the meeting page [2] later this week.

Also, for anyone attending EGU in Vienna in April, we will have a splinter meeting (SMP32) to discuss netCDF-CF. The splinter meeting will be held on Thursday, 21 April 2016 at 15:30 in room 2.96.

Thank you,
