Y

There are approximately 22 GAW stations, which includes the ESRL sites and other national programs. GAW observatories are similar in design to ESRL Atmospheric Baseline Observatories but provide broader spatial coverage. Gas phase observations are made regularly at most sites. The GAW program recommends an extensive set of aerosol measurements, including AOD, light scattering, size distribution. However, only a small fraction of the sites are currently reporting aerosol data to the GAW data center.
