Name

Subroutine UA633 - IRI-90 ionosphere

Synopsis

      RECORD /zgeo/ mgde
      REAL*8        dens(30), tmpi, tmpe
      INTEGER*4     nsp, ksp(nsp), ifail
      
      CALL UA633 (mgde, nsp, ksp, dens, tmpi, tmpe, ifail) 

Arguments

mgde

Geographic location (geodetic coordinates) [in]

nsp

Number of species [in]

ksp

List of species code [in]

dens

Number density (see note of subroutine UA630) [out]

tmpi

Ionic temperature [out]

tmpe

Electronic temperature [out]

ifail

Error flag (see diagnostics) [out]

Description

The subroutine UA633 interfaces the UNILIB libray with the ionospheric model IRI-90. The subroutine includes also a plasmaspheric extension of the model. The species included in the model are H⁺, He⁺, N⁺, O⁺, NO⁺ and O⁺₂ (code 20, 21, 23, 24, 27 and 28, respectively). The subroutine makes use of the arguments matm.ut, matm.rzss, matm.fkpx and kflag() of common block UC150. The indices 27 to 39 of argument kflag are used to control the IRI-90 model. The argument matm.fkpx is used only in the plasmaspheric extension. Note that the different arguments of common block UC150 can be initialized with the help of subroutine UA610.

History

In version 2.00 and earlier, the local time was improperly passed to the IRI model. From version 2.01, the argument kflag(39) has been introduced to control if the IRI model either has to depend on the Sun spot numbers (default) or on the F_10.7 radio flux.

Diagnostics

-63301, illegal species code
-63302, component not allowed in the model
