Have done the best I can at placement of Lacrosse 2811. Gives quite accurate readings when compared to CWOP quality control data. Problem is, I have an approximate .9 degree error of “to warm”, during day average, and a .6 d. average error at night of to cold. If I use offset to correct for the day it just adds to the error during the night. Humidity and wind offsets allow to correct for differnt conditions, i.e. slope for humidity or direction for wind, but I can’t see how I can adjust nightime temperatures differntly than daytime temperaters. Is this possible? Any help is appreciated.
