Zusammenfassung |
The Langley plot method applied on the Brewer Ozone measurements can provide
accurate Aerosol Optical Depth (AOD) in the UV-B. We present seven intercomparisons
between AOD retrieved from Brewer Ozone measurements at 320 nm and AOD measured by
CIMEL sunphotometer at 340 nm or 440 nm (shifted to 320 nm in using the
Angström's law), which are stored in the international AERONET database.
Only the intercomparisons between co-located instruments can be used to
validate the Langley Plot Method applied to the
Brewer measurements: in this case, all the correlation coefficients are above 0.82. If the instruments are not
at the same site, the correlation between the AOD retrieved by both instruments is much lower.
In applying the Angström's law the intercomparison is improved compared to previous study. |
