Sharing netCDF data with WIS2box

[callumrollo]

Hi all,

I'm very new to sharing data via WIS2, so apologies if this has an obvious answer already.

I have a test WIS2box running and now I want to try sharing some of our own data. We have near real time oceanographic data from ocean gliders. Currently we produce timeseries-like netCDF files of pressure, temperature, salinity etc. https://observations.voiceoftheocean.org/

I have been struggling to get these datasets into WIS2. The demo data are all in the BUFR format, and I haven't yet found a library that can convert our netCDF data into the glider BUFR format Table D: Category 15 (oceanography), Table reference 3-15-012 that was added to wmo-if/BUFR4 earlier this year wmo-im/BUFR4#146

I have not worked with BUFR before and I'm struggling to make valid BUFR files. Could someone point me toward a good resource for making this transformation?

I remember reading that WIS2 will be able to take in data in formats other than BUFR. Is this currently the case? If I convert our timeseries data into a csv file, could I use https://github.com/wmo-im/csv2bufr to pull it into WIS2? Or is it best to make BUFR files?

Many thank
Callum

Hi Callum,

Apologies for the slow reply, I've been working on other things but have recently returned my focus on to the WIS2 (and wis2box). I might be able to help with the conversion to BUFR, alternatively NetCDF is a valid WMO format. The WMO Manual on Codes (WMO-NO. 306, Volume I.2) is in the process of being updated to include NetCDF and two profiles based on the CF-Conventions, one for trajectory data and the other for CF-Radial (weather radar). I'm about to travel and be out of the office for the next 3 weeks but should be able to help more after then. Until then, the NetCDF profile can be found at: https://community.wmo.int/en/activity-areas/wis/wmo-cf-extensions and the WMO-CF Marine Trajectory.

Best regards,

David Berry.

Thanks for the linK! I'll work on making our netcdf data compatible with the ocean profile standard.
