SGP/SIRS/E13 - Diffuse Pyranometer Thermal Offsets
DataStreams:sgpsirsE13.a0, sgpsirsE13.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Additionally, the Model PSP radiometer has been replaced by a Model 8-48 which uses a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/C1/E13 - Incorrect calibration coefficients

Description:
After the DIR changeout on 8/27, the DLH measurements at the central facility vary 
significantly between pyrgeometers by as much as 65 Wm^(-2).  It was discovered that the two 
downwelling pyrgeometers destined for C1 and E13 may have been swapped during installation.  
The instrument mentor is unsure of applied calibration coefficients during this DQR's 
time period.  Backing out new downwelling longwave irradiances would be difficult in this 
case. Fortunately, the problem period is less than a fortnight.

SGP/SIRS/E13 - Monthly Report
DataStreams:sgpsirsE13.b1
Description:
:Data quality this site-month is good. The offset for the Global PSP is about -7 W/m^2.
The dominant problem here is the daytime 3 component problem. Direct and Diffuse are
always too high and Global is too low. The problem occurs around the time that the
testing regime switches from twilight to daytime testing regimes or from daytime to
twilight. The flags occur in significant numbers on the 1st - 5th, 7th - 20th, 24th - 
28th,
30th, and 31st. The failures vary in magnitude and duration. The worst flags for a 
particular

respect to this problem. Global goes below daytime empirical limits on both the 5th and
6th for substantial periods of time. Diffuse
also goes below daytime empirical limits on the 6th in the afternoon. Upwelling Longwave
is
below empirical limits on the 24th. This may not be a problem, as many sites exhibited
the same problem on the same night. Exceptionally cold temperatures may be the cause.

SGP/SIRS/E13 - Reprocess: incorrect calibrations
DataStreams:sgpsirsE13.00, sgpsirsE13.b1, sgpsirs20sE13.a0
Description:
After a long data gap on 5/25/2005, presumably a power outage, the following datastreams 
were showing incorrect values as well as incorrect calibration coefficients in the 
datalogger program:
down_long_hemisp_shaded (downwelling PIR instrument)
up_long_hemisp (upwelling PIR instrument)
short_direct_normal (NIP instrument)

The SIRS.E13 datalogger was power cycled (6/2/2005 2200GMT) and the correct program loaded 
into the SIRS datalogger and storage module.

The data during this time range can be recalibrated as follows:
First divide value by incorrectly applied cal coeff (first number) then multiply by 
correct cal coeff (second number)
  short_direct_normal           120.28	124.58

SGP/SIRS/E13 - Reprocessed: Longwave Calibration error
DataStreams:sgpsirsE13.b1
Description:
Modified pyrgeometer calibration procedures were implemented beginning in December 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 October 2006.

Description:
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.

SIRS NIPs affected by condensation at E8, E11, E13, & E15
DataStreams:sgpsirsE8.a1, sgpsirsE11.a1, sgpsirsE13.a1, sgpsirsE15.a1
Description:
Comparison of data from the unshaded PSP to that derived from the 'direct
+ diffuse' (NIP + shaded PSP) indicated low values of the 'direct+diffuse' combination 
starting at sunrise and lasting for about an hour at E8, E11, E13 and E15.
Futher examination revealed that the NIPs were reading low and were likely
affected by condensation during this brief period. Weather conditions were
foggy over the area early that morning, and fog quickly dissipated after 
sunrise.

Reference Broadband Shortwave Data at SGP Central Cluster during Fall IOP '97
DataStreams:sgpbsrnC1.00, sgpbsrnC1.a0, sgpbsrnC1.a1, sgpsirsE13.a0, sgpsirsE13.a1, sgpsirosE13.00,

Description:
This is a recommendation for the best available broadband shortwave data from the SGP 
Central Cluster (Lamont, OK) during the Combined Fall IOP, 15 Sept - 5 Oct 1997.

Data available from the SGP Radiometer Calibration Facility (RCF) has lower measurement 
uncertainties than similar measurements from the C1, E-13, and BSRN/BRS platforms.

The RCF data were collected using the same Broadband Outdoor Radiometer CALibration 
(BORCAL) system used for routine calibration of pyranometers and pyrheliometers at the RCF.  
The data are available for 30-second interval.  
Direct normal irradiance measurements from a windowed RCF Absolute Cavity Radiometer 
during the IOP is considered more accurate (+/- 0.5%) than the Normal Incidence Pyrheliometers 
(NIP) at the Central Cluster (+/- 2%).
The Automated Hickey-Frieden cavity radiometer is electrically self-calibrating and 
provides reference standard data suitable for the calibration of the NIPs used at all the CART 
sites.

Diffuse horizontal irradiance is available as the average of two Eppley Precision Spectral 
Pyranometers and is considered slightly more accurate than the downwelling diffuse (DD) 
data from the Central Cluster instruments.
The RCF data will have periodic gaps during the electrical calibration intervals (about 
6-10 minutes, 4 or 5 times per day).
The reference global horizontal (or Downwelling Shortwave - DS) has been computed from the 
measured direct normal and diffuse components:
DS = NIP x Cos(Z) + DD,
where, Z = solar zenith angle.

All RCF data collected during the IOP are on the ARM IOP Web page 
(iop.archive.arm.gov/arm-iop). 
with other data from the Fall97 shortwave IOP.

Additional corrections to the diffuse data may be possible after researching PSP nighttime 
offsets.

Data from C1, E-13, and BSRN/BRS platforms during the SW-IOP '97 are still being 
investigated.

Description:
Data quality for this site is good this month: 100% of the daytime data are present, and 
89.8% of the present daytime data earn passing or low-level flags. Another 8.8% of the 
present daytime data are assigned strange-but-true flags. Low-level flags seen early on 
clear or partly cloudy mornings indicate that the DS is too low or the DD or NIP too high by 
the three-component test. Overcast conditions force the DS and DD below twilight or 
daytime empirical limits on a number of occasions, and the NIP repeatedly falls below daytime 
empirical limits on the afternoon of the 13th. On the afternoon of the 14th the 10m tower 
was removed for upgrade, so the US and UIR signals read 99999: missing data. On the 
morning of the 22nd the suntracker failed, but was returned to proper operation that same 
morning. No other problems noted.
