Description:
The Barrow facility experienced a site-wide power failure on 12/13.  Power was restored to 
most instruments between 2250 and 2330 GMT.

NSA/AERI/C1 - Excessive Noise in C1 AERI data
DataStreams:nsaaerich1C1.b1, nsaaerisummaryC1.b1
Description:
Initially it was believed that the greater noise level in AERI C1 data was due to the 
extended range detector, which has lower sensitivity. However, when the S01 AERI was 
installed next to the C1 AERI and it stabilized on 9/30/2005, it was observed that the noise 
levels on the newly installed S01 AERI were much lower than for the C1 AERI. Therefore, the 
excessive noise of the C1 AERI is not due to the fundamental nature of the extended range 
detector but instead due to failure within the detector. 

The failure could be due to a poor D* value of too high a detector temperature. It could 
also be caused by optical alignment issues. In either case, the spectral radiance data 
have much more noise and that results in larger error bars when using the radiance data, 
especially long wave data as monitored by the LW_HBB_NEN flag.

On 9/30/2005, the S01 AERI, which is next to the C1 AERI, came on-line and is producing 
low noise data. The S01 data should be used instead of the C1 data where low noise 
requirements are needed.

On 6/26/2006, the S01 AERI went offline due to a laser failure.  The C1 AERI was moved to 
the connex where data were within reasonable limits for an extended range detector.  
Beginning 20060701, the C1 data are the preferred AERI data set at the NSA Barrow location.

Description:
The AERI had high levels of noise and testing was conducted to determine the cause of the 
noise.  These tests occurred June 27 through June 30. Data collected during this time 
should not be used. It was collected to test the instrument and does not represent 
atmospheric data.

The instrument was restarted in the connex using the upgraded Windows rapid sampling 
system on June 30, 2006 beginning 17:00 GMT.

Description:
On 18 Oct 2006, a thermistor that measures the temperature of the blackbody support 
structure failed, resulting in erroneously high values.  This measurement, which is captured by 
the field "BBsupportStructureTemp", provides the temperature of the radiance that is 
reflected into the blackbody (i.e., captured by the field "calibrationAmbientTemp"), and 
thus the calibrated radiance (the field "mean_rad") was incorrect and outside the ARM 
specification that the AERI data should be absolutely calibrated to within 1% of the ambient 
radiance.  The broken thermistor was fixed on 22 Nov 2006.

Fortunately, since the emissivity of the blackbodies is so high, absolute accuracy of the 
calibrationAmbientTemp is not required but should be within a few degrees.  The radiance 
data have been recalibrated using the ambient blackbody temperature (the field 
"calibrationCBBtemp") as a surrogate of the calibrationAmbientTemp. Historically, the 
calibrationAmbientTemp and calibrationCBBtemp measurements have been within 1-2 deg. As a result of 
this recalibration, the radiance data are now absolutely calibrated to better than 1%.

NSA/AERI/C1 - Snow in enclosure
DataStreams:nsaaeriC1.00, nsaaerich1C1.b1, nsaaerich2C1.b1, nsaaerisummaryC1.b1
Description:
A heavy, wet snowstorm late on April 17th and early on the 18th resulted in wet snow 
packing around the arms of the AERI's hatch controller.  This resulted in the ventilator fan 
not shutting down when the hatch closed, and thus snow was packed into the front of the 
AERI (i.e., around the scene mirror and blackbodies).  The data for this period should not 
be used.

NSA/AERI/C1 - Reprocessed: Failed temp sensor affected calibration
DataStreams:nsaaerich1C1.b1, nsaaerich2C1.b1, nsaaerisummaryC1.b1
Description:
The blackbody support structure temperature sensor on the NSA.C1 AERI were biased high by 
approximately 25K beginning 20071217 and became progressively worse until the sensor was 
replaced 20080213.  The temperature from this sensor is used to calibrate the radiance 
data for the AERI.  The AERI data have been reprocessed by replacing the data from the 
failed sensor with the cold blackbody temperature sensor data and producing 
corrected/recalibrated radiance data.

The reprocessed data were archived in March 2008.

NSA/AERI/C1 - AERI infiltrated by packed snow
DataStreams:nsaaerich1C1.b1, nsaaerich2C1.b1, nsaaeriengineerC1.b1, nsaaerisummaryC1.b1
Description:
A strong storm with blowing and drifting snow occurred March 9th and 10th during which 
time the hatch remained open and snow entered the front end of the AERI enclosure.

During the period, the snow obscured scene mirror views of downwelling radiance as well as 
views into the Black Body cavities which provide reference radiances used for 
calibration. Snow also collected around components inside the enclosure thereby possibly 
interfering with scene mirror views after the storm until the snow was removed and the front end 
compartment was dried late on March 13th.

Possible corrupting effects apply to all measurement data streams. Measurements are 
probably bad during the period of the storm and suspect following the storm through March 13th.

NSA/AERI/C1 - Partial data collection
DataStreams:nsaaerisummaryC1.b1, nsaaeriengineerC1.b1, nsaaerich1C1.b1, nsaaerich2C1.b1
Description:
A corrupt file was found to be crashing the AERI software after approximately 30 minutes 
of data were collected each day during this time period.

With the minimal data collected each day it is advised that data users choose dates 
outside of this time range for research requiring AERI data.

Subject:
NSA/AERI/C1 - Hatch status in datastream suspect
DataStreams:nsaaerich1C1.a1, nsaaerich1C1.b1, nsaaerich2C1.a1, nsaaerich2C1.b1
Description:
The AERI has an external hatch that covers the foreoptics in precipitating conditions to 
minimize the exposure of these foreoptics (and in particular the scene mirror) to rain.  
Physical limit switches are used to detect if the hatch is open or closed, and the hatch's 
status is determined by the hatch controller and included in the AERI datastream.  
During this period of time, the hatch was determined to be indicated as open too frequently.  
Analysis of several case studies suggested that the hatch was actually opening and 
closing properly but that its status was not being correctly reported by the hatch controller 
to the datastream.

This is a problem because the hatch may be indicated as open in the datastream when in 
reality it was closed; this would result in biases and misinterpretation of the data.

In late-2008, the AERI mentors were able to figure out the problem with the hatch 
controller and resolve this issue. 

An algorithm was written to determine the hatch status from the observed spectrum.  This 
algorithm was applied to all AERI spectra at the NSA site from Jan 2000 to August 2010; 
monthly netCDF files with the update flags are available as a PI product.  Details of the 
method, and monthly distributions of the hatch condition, are in a report that is included 
with the data.  The report demonstrates that the seasonal distribution of hatch 
open/closed conditions is much more uniform year-to-year, and much more realistic based upon the 
known seasonal dependence of precipitation at the NSA site.
