Hi Ethan, I’m glad Steve brought up the “aggregation” topic. On this topic, it would be interesting to see if anyone has successfully come up with a standardized schema to aggregate satellite-derived Level 2 swath grid structures.
I know there’s an aggregation implementation in the latest OPeNDAP release, but it remains to be seen what this might look like for Level 2 (and perhaps even Level 1) swath grid structured datasets. I don’t know of anyone who’s successfully tested and released an operationally working instance of that part of OPeNDAP for swath grid structured datasets.

"UGRID" -- Of interest to the coastal ocean modeling community, and stuck in a holding pattern for quite a long time, is the harmonization of mesh/unstructured grid coordinates into the main body of CF. The work is mostly completed ... 2. "Aggregation" -- CF structures to link multiple files into larger conceptual datasets. Time series aggregations, union aggregations (associated variables in separate files), and ensemble membership are the most obvious applications of this. Another important application is "tiled grids" (ref. the "gridspec" proposal). - Steve ============================================ On 3/27/2016 9:24 PM, Ethan Davis wrote: 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.
