ua632 - MSISE-90 atmosphere

subroutine  ua632(mgde, nsp, ksp, dens, tmpn, ifail)

Parameters:

• mgde [zgeo,in] :: geographic location (geodetic coordinates)

• nsp [integer4,in] :: number of species

• ksp (nsp) [integer4,in] :: list of species codes

• dens (30) [real8,out] :: number density (see note of ua630())

• tmpn [real8,out] :: temperature

• ifail [integer4,out] :: error flag (see Diagnostics)

Description

The subroutine ua632() interfaces the UNILIB library with the atmospheric model MSISE-90. The species included in the model are H, He, Ar, N2, O2, O. and N. (code 1,2,4,8,9,16 and 17 respectively). The subroutine makes use of the arguments matm.ut, matm.f107a, matm.f107, matm.apind(), and kflag() of common block uc150. The first 26 elements of argument kflag are used to control the MSISE-90 model. Note that the different arguments of common block uc150 can be initialized with the help of subroutine ua610().
