The average hourly reading is converted to microEinsteins per sq. m. per hour and summed over 24 hours to obtain daily Einsteins per sq. m. Winter measurements may be inaccurate due to snow cover.

Photosynthetically active radiation (PAR) is measured every five minutes with an average recorded hourly using Licor PAR sensors (LI-190SZ Quantum sensor). Sensors are returned to Licor for recalibration every two years.
