Purpose : Interface subroutine to photochemical C model for Titan GCM. 7 ! ------- 8 ! The subroutine computes the chemical processes for a single vertical column. 9 ! 10 ! - Only tendencies are returned. 11 ! - With moyzon_ch=.true. and input vectors zonally averaged 12 ! the calculation is done only once per lat. band 13 ! 14 !

Vatant d'Ollone 20 ! + 02/17 - adaptation for the issu du generic 21 ! + 01/18 - 03/18 - Major transformations : 22 ! - Upper chemistry fields are now stored in startfi 23 ! and defined on a pressure grid from Vervack profile 24 ! - Altitudes above GCM top are computed using correct g(z) 25 ! to be coherent with obs and with dz=10km for UV processes 26 ! but this should be even better if all physiq "under" was doing this ! 27 ! - These modifs enables to run chemistry with others resolution than 32x48x55 ! 28 ! - Only the actinic fluxes are still read in a 49-lat input but interp. on lat grid 29 ! - Chemistry can still be done in 2D 30 ! -> Calcul. once per band lat and put same tendency in all longi. 31 ! Check for negs in physiq_mod. 32 ! -> If procs sharing a lat band, no problem, the calcul will just be done twice. 33 ! -> Will not work with Dynamico, where the chemistry will have to be done in 3D. 34 ! ( and there'll be work to do to get rid of averaged fields ) 35 ! 36 ! + STILL TO DO : Replug the interaction with haze (cf titan.old) -> to see with JB. 37 !--------------------------------------------------------------------------------------------------------- 38 39 ! -------------------------------------------------------------------- 40 !
