Description: | Documented in instrument DQR D071022.4. 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. |
