GLOBE Aerosol Optical Thickness Data
The graphs below contain AOT values calculated from GLOBE sun photometer data. The GLOBE
AOT calculations do not include corrections for ozone absorption. The data in the graphs
represent
the GLOBE-calculated AOT values minus average ozone corrections -- 0.01 AOT units for the
505 nm (green) channel and 0.03
AOT units for the 625 nm (red) channel.
The data shown below are divided into two categories based on the
1-5 data quality control
flag system used for GLOBE AOT values. Flag values 1-3 are represented by solid
symbols and values 4-5 are represented by open symbols. The data includes sets of measurements
for which the AOT values are not closely clustered together (flagged as 3). This may be an indication
of cloud contamination or other problems. As a result, values included in the graphs
may still be suspect. On the other hand, it is virtually certain that values
with open symbols are not correct.
The contents of this file are updated from time to time. Each graph gives the
date of the last entry included in the graph. More data about each site, including
