\section{Comparison to GOSAT overpasses}  Compare to NIES retrievals. Correlate with AOD. Examine spatial/pixel location (orography). Links to previous GOSAT-RA work...  \section{Aerosol climatology}  Aerosol light scattering plays a significant role in determining the optical path length of satellite retrievals, and so needs to be well constrained when comparing ground-based measurements with satellites. The aerosol optical depth has been measured by dedicated filter sunphotometers since 2009. The annual cycle derived from these measurements is shown in Figure \ref{fig:aod}.
