ua610 - select an atmospheric, ionospheric and/or plasmaspheric model¶
- subroutine ua610(kmodel, mdate, rzss, f107a, f107, fkpx, ap0, ap3, ap6, ap9, ap24, ap48, lbatm, kunit, ifail)¶
- Parameters:
kmodel [integer4,in] :: index of the model
mdate [zdat,in] :: date and time
rzss [real8,in] :: sunspot number
f107a [real8,in] :: 81-day average of F10.7 solar flux centred on required day
f107 [real8,in] :: daily F10.7 solar flux for previous day
fkpx [real8,in] :: maximum Kp value
ap0 [real8,in] :: 3-hour Ap index for current time
ap3 [real8,in] :: 3-hour Ap index for 3 hours before current time
ap6 [real8,in] :: 3-hour Ap index for 6 hours before current time
ap9 [real8,in] :: 3-hour Ap index for 9 hours before current time
ap24 [real8,in] :: average of eight 3-hour Ap indices from 12 to 35 hours prior to current time
ap48 [real8,in] :: average of eight 3-hour Ap indices from 36 to 59 hours prior to current time
lbatm [character,out] :: label of the model
kunit [integer4,in] :: file unit for the summary table (see note of
ut990())ifail [integer4,out] :: error flag (see Diagnostics)
Description¶
The subroutine UA610 can be used to initialize the atmosphere, ionosphere, and plasmasphere description inside the common block UC150. The argument kmodel allows to select different models listed in the table below.
kmodel
Model description
0
No atmospheric model
1
MSISE-90 neutral atmosphere model including the species H, He, Ar, N2, O2, O. and N..
2
MSISE-90 atmospheric model combined with the ionospheric model IRI-90. The species included are H, He, Ar, N2, O2,O., N., H+, He+, N+, O+, NO+, O+2 and electrons.
3
Anderson & Francis atmospheric and ionospheric model including the species H, He, N2, O2, O., N., H+, He+, O+, NO+, O+2 and electrons.
4
A simple atmospheric model based on table of densities published in “Astrophysical Quantities” (Allen, 1985).
5
Pfitzer atmospheric model
Note that the two last models do not include particular species. These two models provide only the mean density of neutral atmospheric constituents. The MSISE-90 and IRI-90 models depend on a set of flags stored in the common block UC150 for the subroutine UT990 assigns default values. The MSISE-90 model depends on the time, the F10.7 solar fluxes and all the planetary indices Ap. The Anderson & Francis model and the simple Allen model depend on the altitude only. The Pfitser model depends on the altitude and the the F10.7 solar fluxes. The IRI-90 model depends on the time, the sunspot number. The extension of the IRI-90 model to the plasmasphere (Carpenter & Anderson, 1992) depends also on the maximum Kp index.
