Description

This PR contains some of the recent updates to CRTM delivered by STAR https://github.com/JCSDA/CRTMv3/tree/CloudRadar_AirCraft, including:

  • Downward ADA calculation
  • Updated Aircraft level calculation (upwelling radiance at user-defined pressure level)
  • New optional feature for computing downwelling radiance at user-defined pressure level.
  • *The radar updates will be addressed in a separate PR.

Notes:

  • All updates are for forward calculation only. TL, ADA, K-matrix code development under testing.
  • A new unit test has been added, see issue Create unit tests for aircraft level/downward ADA calculations  #158
  • Some of the build file updates can probably be ignored or removed (files under folder src/Build/), given the recent updates to CRTM build system.

Dependencies

None

Impact

Expect changes to CRTM forward results at aircraft level
More scientific validation is needed.

Checklist

  • I have performed a self-review of my own code
  • I have made corresponding changes to the documentation
  • I have run the unit tests before creating the PR

Hi @chengdang, thank you for including me in the review! Is there documentation available from the author for the changes, a report maybe that goes into the math details, so that we can trace back the implementation?

Hi @StegmannJCSDA~ welcome back!

There was no implementation documentation available specifically for this feature. My reference is this book chapter: "Liu and Lu, 2016, Community Radiative Transfer Model for Air Quality Studies, Equation 16(a-b)".
Please let us know if there is any more references @quanhualiu, thank you!

In this code branch, I added some notes to the equations (this will ideally be merged after we merge this PR), you may use this as a reference for code review:

The added notes for codes in ADA_Module.f90 are right and very helpful. I approve the changes.
