O3LABOW

The Labow volume mixing ratio climatology of ozone. This is climatology of the volume mixing ratio from 0 km to 60 km in 1 km increments for 18 latitudes steps of 10 degrees from -85 to +85 for each month of the year. The climatology seems to be unpublished as all references refer to an unpublished piece of work by McPeters and Labow in 2002 or 2003. We have extended the climatology above 60 km using the differences in scale height between the neutrals (7 km scale height ) and ozone (4.5 km scale height) to calculate a new scale height to extrapolate the signal at 60 km. We have also extended the volume mixing ratio so it can be converted to an ozone density. This requires an atmospheric number density climatology for which the MSIS90 climatology is used:

import sasktranif as skif

location = [50.0, -102.0, 12345.0, 53000.327869823]
climate = skif.ISKClimatology('O3LABOW')
climate.UpdateCache(location)
ok, O3 = climate.GetParameter( 'SKCLIMATOLOGY_O3_CM3', location);

Supported Species

• SKCLIMATOLOGY_O3_VMR

• SKCLIMATOLOGY_O3_CM3

Cache Snapshot

The O3LABOW climatology caches the entire LABOW ozone database which provides O3 as a function of geolocation and day of the year

Python extension

The O3LABOW climatology is in the sasktran_core extension which is part of the default sasktran installation.

Configuration

The O3LABOW climatology needs no external preparation.

Properties

The O3LABOW climatology has no special properties.
