Name

Subroutine UA634 - compute mass density from number density

Synopsis

      REAL*8    dens(30), cs(30), tmass
      INTEGER*4 nsp, ksp(30), kflg, ifail
      
      CALL UA634 (dens, nsp, ksp, kflg, cs, tmass, ifail) 

Arguments

dens

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

nsp

Number of species [in]

ksp

List of species code [in]

kflg

Control parameter [in]

cs

Cross section (see note of subroutine UA630) [in]

tmass

Averaged mass [out]

ifail

Error flag (see diagnostics) [out]

Description

The subroutine UA634 averages the number densities of atmospheric component with different weighting. The weighting algorithm is selected by the argument kflg:
• when kflg=0, the number densities are weighted with the atomic mass of the constituents and argument tmass corresponds to the total mass;
• when kflg=1, the number densities are weighted by the atomic mass of the constituents and the factor stored in argument cs;
• when kflg=2, the number densities are only weighted by the factor stored in argument cs.
Generally the argument cs is used to specify a particle cross section.

Diagnostics

-63401, invalid species code
-63402, invalid value for kflg

Common Blocks

UC160, general constants
