Description

**Is your feature request related to a problem? Please describe.**
Some functions, especially related to l3/l4 datasets, consume much memory.

**Describe the solution you'd like**
Where possible, limit xarray caching.

**Describe alternatives you've considered**
Alternatively, processes could be forked to ensure data is purged when the forked process terminates.

**Additional context**
I strongly believe it is the xarray caching that floods memory based on `memray` analysis. However, I'm not sure.

Research direction

Start by locating the functions that process l3/l4 datasets and review the reported memray analysis. Determine whether xarray caching causes the memory growth; done means reducing the memory footprint where possible or documenting why the proposed alternatives are needed.
