| Description: | Beginning October 3, 2007, the upwelling longwave irradiance (up_long_hemisp, aka "UIR")
started to spike to unreasonable values positively offset from the co-located E13 by over
100W/m2. On January 17 2008 the UIR values become consistently bad due to bad UIR dome
thermistor wiring. Problem appears as a resistive offset in the dome thermistor but due
to nature of failure (unknown cable problem) data correction would not yield any better
data than the co-located E13 UIR instrument that is known to be operating correctly.
Instrument cable replacement on 4/22 fixed the problem.
Thermopile data (netIR) from this instrument is good. However, Incoming irradiance data
is not correctable due to bad UIR dome thermistor wiring within the instrument cable. |
