Has anyone ever reviewed the code and analyzed the software engineering practices behind the climate models?

I used to take these things for granted and just believe articles and studies like this one but after humongous public failure of Imperial College Coronavirus model I'm not so sure anymore.

We need code and tech reviews in addition to peer review.
