Dear David,
Thanks for the update. The Dobson Unit is also commonly defined as (from
Wikipedia):
"One Dobson unit refers to a layer of gas that would be 10 ?m thick
under standard temperature and pressure
<
http://en.wikipedia.org/wiki/Standard_temperature_and_pressure>^[1]
<
http://en.wikipedia.org/wiki/Dobson_unit#cite_note-0> , sometimes
referred to as a 'milli-atmo-centimeter.' For example, 300 DU of ozone
brought down to the surface of the Earth at 0 ?C
<
http://en.wikipedia.org/wiki/Degree_Celsius> would occupy a layer only
3 mm thick"
That would match better the variable name. So the unit description
should maybe be adapted...
Best regards,
Christophe
