[FEATURE REQUEST] Provide climatology option for lightning NOx #655

Closed msulprizio closed 1 year ago

msulprizio commented 3 years ago

@ltmurray has already provided climatology files for lightning in https://github.com/geoschem/geos-chem/issues/279#issuecomment-646120009. These files are currently available at:

Disclaimers from the README files:

These fields are provided for user convenience when simulating more recent periods than current lightning availability. However, users should always first check with Lee Murray via e-mail to lee.murray@rochester.edu or at http://ees.rochestere.edu/atmos/data for the most recent available lightning products.

Use of climatological lightning flashes is more appropriate than the use of none. However, lightning is no longer co-located with active convective transport of HOx-rich surface air, and the photochemical impact is therefore underestimated. Therefore, time-varying lightning should always be preferred for science applications.

Is this all set to close?

ltmurray commented 2 years ago

I believe so.

msulprizio commented 2 years ago

I think we need to leave it open. I have the file from Lee, but need to actually implement it as an easy-to-access option in HEMCO_Config.rc. I'll aim to do this for 14.1.0.

The pull request (#1628) for this feature has now been merged into the 14.2.0 development branch.
