Replaced HOBO Robot 4 with new one.
temp/rh calibration good
insanity for par calibration. the 4 apogee sensors were too far off. we’ve developed a calibration method versus a new LiCOR par sensor which is set up and will be run tomorrow, then sending the apogee units back to check for any hardware malfunctions.
we’ve also developed a method to calibrate all the top of canopy data as well as interior forest par sensors to new LiCOR par sensors recently calibrated. phew…a mind-boggle to work through!
preliminary calibration work in the morning prior to discovering that something was seriously not right…..
