NSSL MP initialization issue

Opened this issue · 0 comments

Description

Provide a clear and concise description of the bug and what behavior you are expecting.
When warm starting with NSSL microphysics from restart IC using Thompson microphysics, NSSL microphysics assumes number of concentration of all hydrometers are available and enter the warm start mode for microphysics. This led to an initial surge of reflectivity in RRFS ensemble members using NSSL microphysics.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

  1. step 1
  2. step 2
  3. see the bug...

Warm start with NSSL microphysics scheme with restart IC from Thompson microphysics. Check the reflectivity at F00 (the first timestep)

Additional Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.
