DATE Date: Month-day-year (Day Of Year: Julian Day)
TIME Time in 12 hr format (Hour : Minutes : am_pm)
Tin Air temperature inside the greenhouse (°C).
The aspirated sensor is located 6' above ground, at the middle of the centerline of the greenhouse
RHin Relative humidity inside the greenhouse (%)
Same location of Tin sensor
Tout   Air temperature outside the greenhouse (°C)
This sensor is shielded from sun, and located 22' above ground in the centerline of the south side of the greenhouse
Solar Radiation Solar radiation outside the greenhouse (W/m2) [in the range of 380-1100 nm]
Same location of Tout sensor
CO2 Atmospheric carbon dioxide concentration inside the greenhouse (ppm) is measured with a diffusion sensor located 6' above ground level and 12' from the north wall and at the centerline of greenhouse
VPD Vapor Pressure Deficit [kPa]. Calculated as a function of Tin and RH
Tc Air Temperature set point for cooling (°C)
Th Air Temperature set point for heating (°C)
