That is a lot of code to add.

Refresh my memory. What bad things happen if the loader has a -l for some library that it turns out not use? Does it show up in ldd?

A partial solution to this is to create a float32 float16 filter so that the data is stored on disk as float16.

Since I was not in a position to use python xarray directly, I tried the following instead. Note that I was using the current netcdf-c master, not 4.8.1 1. I...

Ok, I can think of two reasons for this. 1. netcdf-c is not finding the filter (libz aka deflate) used in the file. 2. the python code is writing information...

Assuming that filters are the problem, can you tell me where you are storing them? Perhaps you are setting HDF5_PLUGIN_PATH, and if so, what is its value?

I was able to successfully ncdump the generated file you sent. So I am pretty sure the problem has to do with filters access. Verion 4.8.1 was still a bit...

Well, we can give it a try. First, what operating system and machine are you using? Perhaps you can send me the output from the command "uname -a"

It looks like we are out of luck. In order to get this to work on a Mac, you will need to upgrade to netcdf-c version 4.9.0. Sorry.

Yes, when a dataset variable/array is written, it might have had compression applied to its data to save space. Compression is supplied by a piece of code -- a module...
