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. Oscar monitors a number of environmental parameters via a Davis weather station, including external temperature, pressure, humidity, wind speed and direction, solar radiation, rainrate and leaf wetness. These parameters are used to decide when to open the environmental protection cover (see Figure xx). Measurements are then taken when the solar intensity is sufficient to instigate active tracking; that is, when the tracker diode signals cause the tracker to move from the calculated sun position (TPS - Tracker Position Sun) to the tracker position (TTM - Tracker Tracking Mode).
