During the very good presentations of Julian and Sadie, questions were raised about validation of NetCDF data.
Some people pm me for further information on my comment so here we go.
Just to introduce myself, I'm working on the climate indices computation python library [ https://icclim.readthedocs.io/en/latest/python_api.html | Icclim ] which, for its newest version, will wrap it's sister library [ https://xclim.readthedocs.io/en/stable/ | Xclim ] .
Icclim is founded by IS-ENES, Xclim by Ouranos and both are open source.
In short, both library compute ECAD indices ( [ https://www.ecad.eu/documents/atbd.pdf | see PDF ] ) and others climate indices with a different level of abstraction.
The ECAD specification also gives recommendations about the quality checks to validate netCDF files in chapter "Quality Control".
Here is a (very) short sample of what should be controlled:
daily maximum temperature TX:
. . . must exceed -90.0 ◦C
. . . must be less than 60.0 ◦C
. . . must exceed or equal daily minimum temperature (if exists)
There is currently some work going on in Xclim to run most of these ECAD checks.
However, this is still a work in progress !
The checks may become available though the Xclim CLI, so even if you don't care about climate indices the feature may still become available independently at some point.

Dear valued attendee of the summer school,
we are looking forward to our summer school at the end of the month.
Here is some last-minute information.
1) In case you want to attend the lab practicals, you may want to
download the summer school VM which comes with an environment that
allows you to follow these practicals. More information here:
2) We will be using BigBlueButton using the link below:
To test that it works for you, please use:
3) Please do not unmute or show your video except during Q&A time.
However, we encourage you to ask questions at any time using the chat.
4) We will be recording the sessions, thus, if you show yourself, you
will be part of the recording.
Let me and Jack know if you have any further questions.
