MS050

Attribute: PAR_METHOD

code		description
PAR001		Photosynthetically active radiation (PAR) is sampled by a Campbell Scientific model LI190SB LI-COR sensor attached to the tower at 625 cm height; mean PAR is output every 15 minutes
PAR002		Photosynthetically active radiation (PAR) is sampled by a Campbell Scientific model LI190SB LI-COR sensor attached to the tower at 625 cm height; mean PAR is output every 5 minutes with maximum PAR based on 15 second instantaneous readings
PAR101		Mean daily photosynthetically active radiation (PAR) is calculated by the Campbell Scientific datalogger based on 15 second samples. Max values are based on 15 second instantaneous readings; CS model LI190SB, 625 cm height (See Method PAR001)
PAR102		Mean daily photosynthetically active radiation (PAR) is post-calculated from all 5 minute mean values for the day. Max values are based on the max 15 second instantaneous reading recorded every 5 minutes; CS model LI190SB, 625 cm ht. (See Method PAR002)
