Temporary products not written to scratch directory defined by RunConfig

[collinss-jpl]

While testing the DSWx-S1 and DSWx-NI deliveries, I discovered that changing the docker working directory to /home/dswx_user (from the default of /home/dswx_user/scratch) resulted in the following permission error:

This is because there are two locations in the code where temporary products are written to the current working directory ('.') instead of the scratch directory defined by the RunConfig:

• DSWX-SAR/src/dswx_sar/refine_with_bimodality.py

  Line 1501 in c88902c

  scratch_dir='.')

• DSWX-SAR/src/dswx_sar/refine_with_bimodality.py

  Line 1524 in c88902c

  scratch_dir='.')

Redefining the container working directory is useful for PGE/SDS integration, so it would be nice if these temp products could get written to defined scratch directory like other temporary products.

Hi @collinss-jpl This issues were resolved in the most recent patch release (DSWx-S1 v0.4.2 ).

Hi @oberonia78, I was just able to verify the fix during acceptance testing of the 4.2 delivery, thanks for the quick turnaround!

Hi @oberonia78, I've been seeing this issue crop up again in the interface delivery for DSWx-NI. Seems like the fix for the issue was only merged to the dswx-s1-calval branch, and not the main branch, so it was not included with the DSWx-NI delivery.

Thanks @collinss-jpl for reporting the issue. We are planning to merge the recent changes for dswx-s1-calval to the main branch (#89). This issue will be fixed in the next delivery.
