Tower Gill sonic plots screen before downloading data
  1. downloading data Yes!
  2. check the fans of air temp. and relative humidity sensors on the tower and the floor. Yes!
  3. Joe moved the rain gage to a new place to reduce influence of bars.
  4. Check calibration cylinders;
CO2 2100 psig; flow 20 psi. 384.08 ppm
N2 1550 psig; flow 20 psi.

Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt

Is the pump running‌ Yes!
