Re: subroutine to convert O3 (kg/kg) in NCL

This does not require a "subroutine" or function.
This is strictly a units conversion question.
It is not even an NCL related question.

The following may offer you some help:

    http://wdc.dlr.de/data_products/SERVICES/PROMOTE_O3/vmr.html

Some constants that may help you:

   DUcm = 2.6910^16 ; Dobson Unit: 1DU=2.6910^16 molecules/cm2
   DUm = 2.6910^20 ; Dobson Unit: 1DU=2.6910^20 molecules/m2
   DUmmom = 0.4462 ; Dobson Unit: 0.4462 millimoles of ozone/m2
   DUkgm = 2.1415E-05 ; kilogram [ozone] per square meter
