SGP/SIRS/E24 - SIRS Signal Cable Damage at E24
DataStreams:sgpsirsE24.00, sgpsirsE24.01, sgpsirsE24.a0, sgpsirsE24.a1
Description:
Cattle from adjoining field had broken the electric fence wire around the equipment and
chewed radiometer cables in half adn damaged the shading arm(s) on the SciTec tracker.

The NIP and DD shortwave data collected during this time were recorded  by the
logger as 'over-range' or 'open-channel' (with corresponding data values stored as
'-99999') or a numeric value not representative of the real irradiance conditions
due to faulty connections.  Data for this period are to be considered MISSING.

SGP/SIRS/E24 - Diffuse Pyranometer Thermal Offsets
DataStreams:sgpsirsE24.a0, sgpsirsE24.a1
Description:
Broadband downwelling shortwave diffuse (sky) irradiance measurements available from SIRS
during the period of this Data Quality Report (DQR), require adjustment for thermal
offsets.  These thermal, or ?zero? offsets refer to the generally reduced output signals
from a shaded pyranometer due to the exchange of longwave (infrared) irradiance between
the single black thermopile detector, the protective glass domes surrounding the
detector, and the atmosphere. Originally considered an acceptable nighttime response of
thermopile-type pyranometers, the generally negative bias is now recognized to
significantly effect the accuracy of SIRS diffuse irradiance data during daylight
periods.

Studies of the Eppley Laboratory, Inc. Model PSP (Precision Spectral Pyranometer), used
for the SIRS   measurements of diffuse irradiance, suggest the thermal offset correction
can range from near 0 to as much as 30 Watts per square meter, depending on the
coincident net longwave, or infrared irradiance [1, 2].  Under very clear-sky conditions,
the diffuse irradiance from a shaded PSP can be less than the minimum physical limit
defined by radiative transfer model estimates based only on Rayleigh scattering effects.

A correction method has been developed for adjusting SIRS diffuse irradiance data [3]. 
The resulting Value Added Product (VAP) will be applied to SIRS data for the period of
this DQR.  The VAP will not be applied to SIROS data collected before the instrument
platform was converted to SIRS.

Additionally, the Model PSP radiometer has been replaced by a Model 8-48 which uses a
black and white thermopile detector known to reduce the thermal offset errors to less
than 2 Watts per square meter [3].  The radiometer replacement at this SIRS location was
completed on the ending date of this DQR.

SGP/SIRS/E27 - incorrect tracking
DataStreams:sgpsirsE27.00, sgpsirsE27.b1, sgpsirs20sE27.a0
Description:
The solar tracker at E27 was not functioning properly.  The problem affected tracker 
mounted instruments: downwelling diffuse 8-48 and direct normal pyrheliometer NIP.  

After tracker adjustment on 4/14/2004 1700GMT the tracker stopped tracking properly during 
afternoon hours.  Attempts to correct tracker operation throughout the failure period 
resulted in variations on incorrect tracker operation.  No replacement tracker was available.

After adjustment on 9/15/2004 the tracker problem was resolved.  It is unclear what, other 
than typical az and zen tracker software changes by field techs, corrected the problem.  
This problem period corresponds to the first time range specified (4/14 to 9/15). 

On 10/27/2004 a replacement tracker was installed at E27.  Technical difficulties kept 
tracker out of service until 11/05/2004. The replacement tracker at E27 was put into serice 
by the field techs on 11/05/2004 1830GMT.  The tracker has been tracking correctly since 
this time.  This problem period corresponds to the second time range (10/27 to 11/05).

Description:
The NIP is shaded by the EF laptop computer enclosure near sunrise during parts of the 
Spring and Summer.  This has occurred from 04/08 to 05/20 and from 07/26 to 09/06 every year 
since 2001 and will occur during these date ranges in the future as well.  The shading 
occurs for a few minutes each day between 1200 and 1300 GMT depending on the time of the 
year.  For the early dates, shading occurs a little after 1200 GMT and by 05/20 shading 
happens nearer to 1300 GMT. In late July the shading occurs near 1300 GMT and closer to 
1200 GMT by 09/06.

DataStreams:sgpsirsE24.b1, sgpsirs20sE24.a0
Description:
The NIP is shaded by the EF laptop computer enclosure near sunrise during parts of the 
Spring and Summer.  This has occurred from 04/08 to 05/20 and from 07/26 to 09/06 every year 
since 2001 and will occur during these date ranges in the future as well.  The shading 
occurs for a few minutes each day between 1200 and 1300 GMT depending on the time of the 
year.  For the early dates, shading occurs a little after 1200 GMT and by 05/20 shading 
happens nearer to 1300 GMT. In late July the shading occurs near 1300 GMT and closer to 
1200 GMT by 09/06.

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.

SGP/SIRS/E24 - Dirt on dome
DataStreams:sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
Description:
The Downwelling Shortwave Hemispheric (DSH) Irradiance data were erratic. The Pyranometer 
instrument dome at this site was likely dirty given the relatively large spread between 
the measured DSH and derived DSH readings during the middle part of the day (up to 50 
W/m^2). Rain on 04/06 most likely contributed to this problem.  Preventative maintenance on 
4/14 effectively cleaned the pyranometer dome.  Preventative maintenance reports indicate 
dry-water spots on dome when it was cleaned on 4/14.

SGP/SIRS/E24 - Reprocess: Incorrect calibration coefficients
DataStreams:sgpsirsE24.00, sgpsirsE24.b1, sgpsirs20sE24.a0
Description:
Calibration coefficient for the downwelling diffuse measurement (8-48 B&W Eppley 
instrument) was incorrect after the instrument replacement 8/18/2005.

Affected downwelling diffuse irradiance data can be corrected:
Irr(corr) = Irr(uncorr) / 122.85 * 112.85 (or a overall multiplier of .9186)

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]

SGP/SIRS/E24 - Reprocessed: Longwave Calibration error
DataStreams:sgpsirsE24.b1
Description:
Modified pyrgeometer calibration procedures were implemented beginning in July 2004. These 
modified procedures introduced a calibration bias in the longwave data. The previous 
procedures were re-implemented at all sites between December 2005 and February 2006 to 
restore proper calibrations. 

The data collected while the incorrect procedures were in place have been reprocessed to 
remove the calibration bias.  The reprocessed 60 second averaged data are based on 3 
instantaneous 20 second data records rather than on 60 1 second instantaneous data records. 
Still, these data are considered far superior to the originally processed data. The 
reprocessed data were archived in October 2006.

SGP/SIRS/E27 - Reprocess: Incorrect calibration coefficients
DataStreams:sgpsirsE27.b1, sgpsirs20sE27.a0
Description:
Logger reverted to previous years configuration, possibly due to power outage and 
non-current logger program in storage module.  Note, the tracker had failed during this period as 
well.

The configurations are as follows:

Data must be reprocessed for all shortwave instruments; longwave instruments are 
unaffected.  The following corrections must be applied:

down_short_diffuse_hemisp(new) = down_short_diffuse_hemisp(old) * 118.49/111.68
up_short_hemisp(new) = up_short_hemisp(old) * 116.66/111.85
short_direct_normal(new) = short_direct_normal(old) * 123.30 / 111.03

SGP/SIRS - SIRS E24 April 1999
DataStreams:sgpsirsE24.a0, sgpsirsE24.a1
Description:
Data quality at this site is very good this month. Nearly all 99.6% of the daytime data is 
present. Passing or low-level flags are assigned to 93.5% of the present daytime data. 
High level flags seen in the first two days of the month indicate that the DD is above 
daytime empirical limits. A diurnal plot for the 1st shows that the suntracker has failed: 
the DD is tracking the DS, and the NIP signal is flat.  Low to mid-level flags observed 
from late morning to mid-afternoon late in the month indicate that the DS is too high by 
the three-component test. Alternatively, the flags may signal that the NIP or the DD is too 
low. The DS and DD were forced below daytime or twilight empirical limits by heavy cloud 
cover on a number of occasions. On the 27th at 1657 GMT the US and UIR signal fields are 
filled with the data logger value representing missing data -  -99999 as if the 
instruments were disconnected. The Operations Management Information Systems Instrument and 
Corrective Maintenance Report for this site indicate that the UIR and US were disconnected and 
the 10m tower taken down for upgrade on the 26th. No problems were noted in the DIR signal.

SGP/SIRS - SIRS E25 April 1999
DataStreams:sgpsirsE25.a0, sgpsirsE25.a1
Description:
Data quality at this site is very good. All daytime data are present. Passing or low-level 
flags are assigned to 91.2% of the present daytime data. Another 5.8% of the data are 
labeled strange-but-true. Low- to mid-level flags in the late afternoon to early evening 
indicate that the DS is too low by the three-component test. Late in the month overcast 
skies drove the DS and DD signals below twilight or daytime empirical limits. Shortly after 
noon on the 14th a possible instance of cloud refraction is recorded in the DS. On the 
afternoon of the 19th the DS and DD signals fall into the physically impossible region of 
K-space. The DD signal is recorded as missing (-99999) by the data logger in a few 
short-lived instances (1-3 in duration minutes each) early in the afternoon of the 25th. Both 
the UIR and DIR signals continue to be noisy. No problems were noted in the US signal.
