chemthermos.F90 @ 2325

Last change on this file since 2325 was 2042, checked in by emillour, 6 years ago

Mars GCM:
Modifications to use the parametrized photoabsorbtion coefficients;
a first step towards implementing ionospheric chemistry in the new
chemical solver:

change in species indexes in chemthermos.F90, paramfoto_compact.F, hrtherm.F and euvheat.F90
calchim.F90: added a variable in call to photochemistry
photochemistry.F90: added calls to jthermcalc_e107 and phdisrate, with an additionlal flag, jparam (.false. by default). The computed photodissociation coefficents are sent to v_phot, which is used in the chemistry. Thus concentrations computed in chimtogcm are now done over all atmospheric layers.
