For the NIR measurements, the instrument follows standard TCCON configuration \cite{Washenfelder_2006,Wunch_2011}. An updated Bruker solar tracker with 80mm mirrors is used. Pressure sensors... other MET instrumentation. The automation is run by in house developed software "`Oscar"', which communicates with OPUS via DDE interface under Windows.   Aerosol optical depth has been measured since 2009 using Middleton Solar SP02 Sunphotometers mounted on an active altitude - azimuth tracker as used by the Bureau of Meteorology \cite{Mitchell:2003kd}. The sunphotometers have been changed intermittently, and hence the wavelengths measured have altered during the measurement period. The calibration procedure involves analysis of suitable clear morning or afternoon periods \cite{Mitchell:2003kd}. Aerosol optical depths have been calculated using the minute observations, filtered for cloud  \cite{Mitchell:2003kd} and then averaged to hourly values provided 6 measurements exist in that hour (10 \%).
