HALOE
Aerosol Climatology
A climatology of aerosol extinction at
four wavelengths (2.45, 3.40, 3.46, and 5.26 microns) was developed
from version 19 HALOE data. The climatology reports
monthly zonal means in 10 degree latitude bins on a vertical grid
from 0 to 89.7 km at 0.3 km intervals. The climatology includes
tropopause height, cloud top height, and profiles of pressure and
temperature. See Hervig et al.
[1996] and Hervig and Deshler
[2002] for
discussion of the HALOE aerosol measurements.
