Content of the Venus INPUT directory
====================================

* Directory "cross_sections"
Needs to be in the execution directory when using photochemistry.

* Directory "datagcm"
For the moment, it is not used...
It contains only radiative transfer stuff, and will be used when running radiative transfer modules coming from the G-PCM, such as when using solarchoice=2. 
This is not validated configuration for the moment, so with solarchoice=1, you should be able to run without datagcm.

* Directory "HIGHATM"
Needs to be in the execution directory when using thermosphere (78- or 90-level configurations).

* Directory "solar_fluxes"
Needs to be in the execution directory when using thermosphere (78- or 90-level configurations).

* jvenus.20220321
Needs to be present as "jvenus.dat" in the execution directory when using photochemistry with offline photodissociation (NOT the standard configuration).

* For the NER IR module, a file named "ksi_global.txt" needs to be in the execution directory. 
This file depends on the configuration you want to run :
  - ksi50_1lat-Cld6_kdist6_haz1e-6_3e-7_y.Oct2016.dat
    50 levels / Uniform cloud as a function of latitude (NOT standard)
  - ksi50_5lat-Cld6_kdist6_haz1e-6_3e-7_y.Oct2016.dat
    50 levels / Cloud varying with latitude
  - ksi78_5lat-Cld6_kdist6_haz1e-6_3e-7_y.Oct2016.dat
    78- or 90-level configurations
    
* For the SW module with solarchoice=1 (standard):
    SolarNetFlux_RH.dat needs to be in the execution directory

* In order to change the resolution using newstart, you will need a "Relief.nc" file.
This file can be:
  - vt1x1inv.nc         => 1 degree x 1 degree 
  - topo_Thomas_inv.nc  => 1/23 degree x 1/23 degree  (8192x4096)
     From the PDS, with sharp edges smoothed out (Credit: Thomas Navarro).
  - topo_stats_VMTG_full_inv.nc => 1/23 degree x 1/23 degree  (8192x4096)
     From the PDS (Magellan data, completed by Pioneer Venus to fill the gaps)
  These files are upside down (South on top, East on the left).
