T_air_vaiptu_std Standard Deviation of Air temperature Degrees Centigrade (°C)
Rel_Hum_vaiptu_std Standard Deviation of Relative humidity Percent (%)
Press_air_vaiptu_std Standard Deviation of Atmospheric pressure Millibars
T_air_vaiptu_len Record length of valid Air temperature Temp between -25 and 35*
Rel_Hum_vaiptu_len Record length of valid Relative humidityRH between 0 and 110*
Press_air_vaiptu_len Record length of valid Atmospheric pressure P between 870 and 1100*

* data also cleaned up after range check by removing outliers (4*std from the mean)

8/4/2005 - Used MC Clements Tree Service cherry picker to remove anemometer sn#145 and install sn#6.

Swapped out the wand on the vaiptu as the old one was not working

Replaced wand 10/23/2012 - but didn't work properly (temps too high); reseated 11/5/2012

Vaisala Model PTU200AAB1AB Serial#V1830001
Wand Serial# V1130014

Replaced wand 11/20/2012 -

Vaisala wand V1130014 was not reporting temperature or humidity. No sign of damage. Swapped out wand and installed V263005. Wand V1130014 works ok in my office. New wand worked for a while but then Temp too low - shut down data flow and MetDat uses shore lab for now.

Replaced wand 5/22/2013 (no details)

as part of routine maintenance.

Vaisala Wand replaced 9/30/2015 (sf)
