| Description: | The THWAPS humidity sensor output was scaled so that the instrument output
voltage range (0-1VDC) represented 0-100 %RH. Comparisons with the
co-located chilled mirror sensor at the CF suggested that the THWAPS RH
sensor was reading artifically low at high humidities because of this 100
%RH maximum.
The scaling of the system was changed so that 0-1 VDC now represents 0-110
%RH. This resulted in a slight loss of precision in the measurements, but
since the RH measurement is only accurate to 2-3 %RH at best, this isn't a
significant problem. |
