Subject: | SGP/SIRS/E24 - Erratic downwelling shortwave data |
DataStreams: | sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
|
Description: | Downwelling shortwave hemispheric readings are occasionally erratic, jumping to very high
or very low values for short periods of time. SGP PM techs reseated all Downwelling
Shortwave PSP instrument connections on 3/17/2005 approx 1945GMT. The problem did not reoccur
after that time but the DS cable was replaced on 3/31/2005 approx 1815 GMT to ensure the
problem did not reappear. |

|
Description: | Upwelling longwave hemispheric data drops out occasionally during the afternoon hours.
Maintenance determined that the Upwelling LW Hemispheric irradiance instrument, the PIR,
had a failed cable affecting only the thermopile measurement of this instrument. Cable was
replaced 7/20/05 2000GMT. |

Subject: | SGP/SIRS/E20 - Downwelling Shortwave PSP Damaged by Lightning |
DataStreams: | sgpsirsE20.00, sgpsirsE20.b1, sgpsirs20sE20.a0
|
Description: | The PSP was damaged by a lightning strike on 8/04/05 (22:10 GMT). Data from other
radiometers are good after this event.
The PSP, NIP and shaded 8-48 were replaced 8/17/05 and the system returned to service at
18:40 GMT.
Downwelling Shortwave (DS) data from the unshaded PSP during this period is reported as
0.0 W/sq m. The DS can be computed from available Direct Normal (NIP), Downwelling Diffuse
(DD), and the computed Solar Zenith Angle (SZA) using the following equation:
DS = NIP * Cos(SZA) + DD
Estimated uncertainties of the computed values are actually lower than those of the
measured DS (+/- 3% or 4% vs. +/- 5% to 10% respectively, depending on SZA). |

Description: | Afer recovery from lightening strike the upwelling longwave SIRS Eppley PIR (UIR) has had
noise on both dome and case thermistor measurements. On 4/12/2006 techs replaced
defective j-panel at base of tower. |

DataStreams: | sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
|
Description: | During the PIR coefficient change from 4/coeffs to 1/coeff, the downwelling diffuse
hemispheric instrument (Eppley 8-48) coefficient was inadvertently changed to 122.85 and should
have been 112.85 W/m2/mV.
Perform the following calculation to correct the data, DD=downwelling diffuse instrument:
DD(new)[W/m2]=( DD(old)[W/m2]/122.85[W/m2\mV] )* 112.85[W/m2/mV] |

Subject: | SGP/SIRS/E21 - Roosting birds in field of view |
DataStreams: | sgpsirsE21.00, sgpsirsE21.b1, sgpsirs20sE21.a0
|
Description: | The RBDD (Rotating Bird Deterrent Device) installed at E21 to prevent turkey vultures from
roosting on the instrument boom failed resulting in noisy NIP (Short Direct Normal) and
PSP (Short Global Hemispheric) data and a spike occurring around 2230 UTC everyday due to
obstruction of the field of view.
Problem is intermittant due to moving birds. Use data with discretion. Follow ARM
(DQMS3) flag recommendations for QC flags 02 or 03 found in section 5.1.4 of the SIRS handbook:

order of magnitude) in data. Problem corrected itself on 12/5 before the site visit on
12/7. It is not known why the problem did not return but instruments affected were on the
multiplexer. Maintenance reports it was not replaced. |
