2 years ago Unfortunately it seems the JOANNE Level-4 data can't be accessed via OpenDAP, for reasons I don't understand, but we should try and work through with Geet.
That's an easy (though annoying one). The reason is described in the How to EUREC4A and it is because the Level-4 data uses variable datatypes incompatible with opendap (namely int64 sounding and int64 circle).
Possible solutions are:
- 🙂 recreate the netCDF such that only compatible datatypes are used (as indicated in the article, I would strongly recommend to stick to those "safe" datatypes as long als anyhow possible)
- 😄 use zarr in stead of netCDF (this should give by far the best access performance, but is probably not yet commonly accepted in the community)
- 😬 modify the intake catalog to access the netCDF directly (in stead of via openDAP) (this should give the worst perfomance, but as the file of concern is only 6.8 M in size, it might be ok)
The values stored in circle and sounding are all in the range [0, 84] and the number of values is small, thus any integer type would work for these variables.
While looking at the file, I'm also wondering why the standard_name of circle is "time"?
@d70-t This updates the data pointed to for JOANNE Level-3 and does a little more grouping of tests for the CI.
