SGP/SIRS/E20 - Diffuse Pyranometer Thermal Offsets

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Additionally, the Model PSP radiometer has been replaced by a Model 8-48 which uses a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/E21 - Reprocess: Incorrect PIR/UIR Calibration Coefficient

Incorrect coefficients were applied to the upwelling longwave radiation
measurement instrument (i.e. pyrgeometer, SIRS acroynm "UIR") during
this time period.

For a PIR mounted in an upwelling measurement orientation (UIR), the
thermopile output is extremely low compared to a downwelling PIR (DIR).
In addition, the UIR case and dome temperature differences are much
smaller than a DIR.  This results in the pyrgeometer receiver radiation 
term, Wr (NREL/Hickey equation) or Wc (Albrecht/Cox equation), dominating
all other terms of the infrared radiant flux equation.

Since the receiver radiation term uses coefficients in both forms of
the pyrgeometer equations nearly equal to 1.0 +- <1% the result is a
measurement of incoming longwave radiant flux relatively insensitive 
to the installed instrument - so long as it is an Eppley PIR.
                
Evaluation of the problem data shows the expected error of the data
(before correction) will be within 1% - less than the uncertainty of 
the instrument (Eppley PIR greater of 5% or 5 W/m2)
                
To correct the one minute data found in the a1 or b1 datastream follow
this procedure:
1) Obtain the following variables from the b1 datafile:
         inst_up_long_dome_temp
         inst_up_long_case_temp
         up_long_netir

2) For each one minute data entry in b1
     tpUIR[uV] = up_long_netir[uV]/0.2523876[W/m2/uV]

3) Apply for each one minute data entry:

WinUIR(W/m2)=k*V+ Sigma*Tc^4 -4*Sigma*(Td^4 - Tc^4)
            =[0.28902*tpUIR]+[Sigma*inst_up_long_case_temp^4]
              -[4*Sigma*(inst_up_long_dome_temp^4-inst_up_long_case^4)]

where, Sigma =  5.6697E-8 (Stefan-Boltzman Const)
                
Other datastream corrections that use the UIR measurements will require
similar corrections.

SGP/SIRS/E21 - Bird Poop Contamination

Downwelling shortwave values were erratic during the day on 10/18 and in very poor 
agreement at times with downwelling shortwave values calculated from direct and diffuse 
measurements. Bi-weekly preventative maintenace records indicate bird poop was cleaned from the 
downwelling shortwave instrument on 10/29 at 16:30.  Review of maintenance records and 
instrument data indicate no bird contamination since 10/29.

Turkey vultures are the usual suspects in data quality problems at this facility. The 
RBD(rotating bird deterrent) had failed the week of 10/13 and is awaiting parts.  However, 
beginning in late October the birds had left the site.

SGP/SIRS/E21 - False signal

During clear-sky conditions, downwelling shortwave values spike downward approximately 50 
to 200 W/m^2 around 22:15 UTC for about 15 minutes. This problem occurs at about the same 
time for the same duration each day during the indicated period of the year.  This 
effect is due to a shadow from the Rotating Bird Deterrent (RBD) installed earlier in the year 
to prevent extensive bird droppings at the site.  The RBD is installed at such a 
location that it will partially shade the downwelling shortwave PSP from 19 October to 23 
February of the year.

SGP/SIRS/E21 - Instrument logger time problem, Unknown

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.

Measured downwelling shortwave values differed from calculated 
              (direct + diffuse) by +/-100 W/m^2 in the afternoon.  Pattern of
              differences is indicative of a dirty downwelling shortwave dome.
              Maintenance on 6/9 cleaned water spots on the dome.  Other 
              downwelling instruments may have also been dirty during this

SGP/SIRS/E20 - Downwelling Shortwave PSP Damaged by Lightning

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).

SGP/SIRS/E21 - Roosting birds in field of view

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:

SGP/SIRS/E20 - Reprocessed: Longwave Calibration error

Modified pyrgeometer calibration procedures were implemented beginning in July 2003. 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 November 2006.

SGP/SIRS/E20 - Failed tracker and improperly configured tracker

On 1/15/2007 the E20 tracker failed due to weather.  On 3/14 it was replaced but 
configured incorrectly (presumably the wrong lat/long).  This wasn't discovered and corrected 
until 6/6/2007 1745GMT.
All shortwave instruments dependent on proper tracker were affected.  This includes 
measurements: downwelling shortwave diffuse and direct normal.  Additionally, the global 
shortwave instrument have also been shaded during the second time range due to improperly set 
tracker.

Ice storms affected the SGP central and extended facilities starting Dec 10 0000GMT to 
mid/late December. Each facility was affected at various times and degrees dependant on 
elevation, latitude and whether power failed for short or extended periods of time.  By 
December 15th most ice had melted from the radiometers at all the faclities but power outages 
and tracker failures persisted at some stations.

SGP/SIRS/E21 - Ventilator Fan Failure

Start time is uncertain due to length of time this problem existed.  During the time frame 
specified the PSP (down_short_hemisp) and 8-48 (down_short_diffuse_hemisp) ventilator 
fans failed. PM replaced the fans 7/1/2008 1500. 
Ventilator failure does adversely affect thermopile radiometer measurements but the extent 
has not been quantified. The 8-48 is significantly less affected than the PSP. Mentor 
suggests using component sum method detailed in SIRS
instrument handbook where down_short_hemisp = down_short_diffuse +
short_direct_normal * cos (zenith angle) for each time record.

SGP/SIRS/E21 - Tracker inoperative

The solar tracker at this site had numerous failures over the time range of this DQR.  The 
result is non-recoverable data for any direct normal (NIP) or diffuse (8-48) broadband 
measurement.  Longwave data is generally unaffected by such failures.

SGP/SIRS/E21 - Tracker failure

First apparent on 03/26, the short_direct_normal values were incorrect after approximately 
1700GMT each day. The tracker was found to have excessive clock drift and was reset by 
site ops on 05/04/2010 and returned to service at 1935GMT. The down_short_diffuse_hemisp 
values appear unaffected by the tracker misalignment.

The short_direct_normal data values are suspect after approximately 1800GMT each day from 
03/26 to 04/26 and after 1700GMT from 04/27 to the end of the period.  The 
short_direct_normal data are not recoverable but can be calculated indirectly using the following 
relationship for each minute of data:
down_short_hemsip = short_direct_normal * cos(zenith angle) + down_short_diffuse

If the E21 system clock drifts the E21 Datalogger clocks will be set to the same incorrect 
time. SIRS irradiance data will be correct but the corresponding time stamp cannot be 
accurately known or simply corrected for.

SGP/SIRS - SIRS E20 April 1999

Good data quality for this site this month. All data are present, and 92.5% of the present 
daytime data earn passing or low-level flags. Another 6.1% of the daytime data are 
flagged strange-but-true. Low-level flags in the early morning hours shortly after sunrise 
indicate that the DS is too low, or the NIP or DD too high by the three-component test. 
Low-level flags seen after noon in the second half of the month indicate that the DS is too 
high. The DS and DD are forced below daytime empirical limits by overcast skies on several 
occasions.  Moderate to serious flags shortly after noon on the 14th indicate that the 
DS signal is too high by the three-component test. On the 22nd at 1605 GMT the 10m tower 
was taken down for upgrade. The UIR and US signal fields will be filled with the data 
logger missing data flag, -99999, until the new tower is installed. Otherwise, data 
collection will continue as usual. No problems noted in DIR signal.

SGP/SIRS - SIRS E22 April 1999

Data quality is excellent at this site this month. Present daytime data is at 100%. Just 
over 98% of the present daytime data earn passing or low-level flags.  In the first week 
of the month low-level flags indicate that the DS is too high by the three-component test, 
or that the DD or NIP is too low. Heavy cloud cover on several occasions caused the DS 
and DD to fall below daytime empirical limits. On the afternoon of the 14th the NIP fell 
below daytime empirical limits for a short time. Shortly before noon on the 26th the DS 
signal was above daytime empirical limits. No problems note in the DIR, UIR or US signals.
