I’ve put together a NetCDF viewer that lets you examine the information in a NetCDF file. The metadata display is complete; the data display is primitive but gets the job done. Currently, it uses the Observable inspector to display a slice of the data as selected by sliders, one per dimension.
The slices are obtained by a reusable extended API atop
I plan to add specialized data displays (e.g. geo, graph, etc.) and generally beat ln it more, but I think it’s already pretty useful for a quick inspection of contents.
