The clock on the aft bulkhead of the Main Lab can be used as a reference. Channel assignments are: P0 = Sonic anemometer (Gill) P1 = Licor CO2/H2O sensor P2 = Means (T/RH, solar and IR flux, seasnake) P3 = Not used P4 = Ophir Fast H2O P5 = Motion-pak P6 = SCS data P7 = GPS Within the individual channels, the data fields are as follows: P0 = Sonic anemometer 1 Time 2 U 3 V 4 W 5 Sonic Temperature (degC) 'Time' is a 14 digit milliseconds count from the computer clock. Note that U, V, and W are sonic-referenced components of the measured uncorrected wind. P1 = Licor CO2/H2O sensor 1 Time 2 Diag 3 CO2 4 H2O 5 Temperature 6 Pressure 'Diag' is a diagnostic, 'CO2' and 'H2O' are in units of mmol per meter cubed, Temperature is in C, and Pressure is in kPa.

'ORG' is the optical rain gauge (carrier and signal), 'RH' is the relative humidity, 'Batt' is the battery voltage of the Campbell datalogger (should be around 13V or so), 'std' indicates that the standard deviation of these channels is output, 'Flow' indicates that the aspirator fan is operational (0V) or if there is backflow (+5V).
