Subject: | SGP/SIRS/E2 - Reprocess: Incorrect shortwave radiometer calibration coefficients |
DataStreams: | sgpsirsE2.00, sgpsirsE2.b1
|
Description: | During the pyrgeometer instrument (PIR) changout a datalogger program was loaded with
incorrect calibration coefficients for the shortwave instruments. The affected measurements
were : downwelling diffuse (DD), upwelling shortwave(US), direct normal (NIP) and
downwelling shortwave(DS)
Recalculate irradiances by determining original mV signal and reapplying the correct
calibration coefficients. For each one minute irradiance value perform the following
calculations by instrument:
DD(corrected) = (DD/107.24)*118.11
US(corrected) = (US/113.19)*118.21
NIP(corrected)= (NIP/120.17)*119.08
DS(corrected) = (DS/118.46)*117.33 |

Subject: | SGP/SIRS/C1 - Discrepancy between measured and derived downwelling shortwave hemispheric |
DataStreams: | sgpsirs20sC1.a0, sgpsirsC1.b1
|
Description: | Measured values of downwelling hemispheric shortwave radiation were up to 40 W/m^2 higher
than derived values during the afternoon hours.
Analysis reveals that this is likely an artifact of the cosine response of the particular
installed PSP coupled with typical uncertainties of this set of installed radiometers.
That is, this particular instrument cluster seems to be producing cumulative errors on
the high side of accepted values.
The PSP contains the most uncertainty in measurement at this station. Users should use a
derived value for the downwelling shortwave hemispheric irradiance (DS). Where DS =
diffuse component + direct normal * cos(SZA) component described in the SIRS handbook Sec 7.2

Subject: | SGP/SIRS/E21 - Instrument logger time problem, Unknown |
DataStreams: | sgpsirs20sE21.a0, sgpsirsE21.00, sgpsirsE21.b1
|
Description: | Values of diffuse hemispheric shortwave radiation differ from derived values by at most 70
Wm^(-2). The incident appears to be isolated to 3/21, 3/22, and 3/23. An estimation of
solar noon using downwelling shortwave hemispheric irradiance from the PSP shows solar
noon to oocur at around 1845GMT on 3/21. Calculated solar noon occurs at E21 at 1831GMT for
3/21/2004. There appears to be a time discrepancy in the datalogger for these dates.
04/01 is the next date with enough sun to determine solar noon and compare to calculated.
The data from this date appears correct. Ronald Reed [rreed@ops.sgp.arm.gov] reports
the logger did not receive any reportable time updates during the late March time period.
We don't know what happened during these three dates but from 3/24 on data looks acceptable. |
