uc150 - atmospheric model

type  uc150

Synopsis

INCLUDE 'unilib.h'

COMMON /UC150/ matm, ntspec, nnspec, kspec, kflag

TYPE(zatm)     matm
INTEGER*4      ntspec, nnspec, kspec(30)
INTEGER*4      kflag(50)

Arguments

matm

Description of the atmospheric, ionospheric and/or plasmaspheric models (zatm)

ntspec, nnspec

Total number of species and number of neutral species

kspec

Indices of the different species

kflag

Internal switches

Description

The common block uc140 contains the description of atmospheric, ionospheric and/or plasmaspheric models used by the subroutine ua630(). The common may be initialized with the subroutine ua610().

The argument kspec provides a list of indices which corresponds to the list of the atmospheric and/or ionospheric constituents included in the selected model. The indices kspec(1:nnspec) are related to the neutral elements while the indices kspec(nnspec+1:ntspec) are related to the ionized elements. The table below shows the correspondance between the index values and the chemical elements.
