Description:
The COST 726 Aerosol Climtology consists of one data file (ascii).
The file contains
Lon, Lat and 12 values of AOT at 308nm for each month ( from Jan to Dec).
The format is: 14F12.2

If altitude is >1km the following correction should be applied: AOT=AOT / (altitude[km])^1.65

further:
Angstrom coefficient: 1
Single scattering albedo: 0.94
Asymmetry factor: 0.75

If you have any questions/comments, please, contact by email: chubarova@imp.kiae.ru
