CF local time) per ECR-00226 and BCR-00491.

This change brings all ARM TSIs to the same operational
sampling rate.  Daily SGP TSI data volume will decrease
by about 1/3 due to this change.

---------------------------------------------------

Due to the high aerosol conditions at Niamey, the TSI appeared to be beyond the limits of 
processing the color JPEG image into cloud fraction values. Several attempts to adjust 
the sky filter values used to process the images did not yielded the desired results. The 
processed images indicate an opaque sky cover, even in the absence of clouds.

The problem was corrected by removing the neutral density filter from the lens and 
re-adjusting the sky filter values.

The data can be reprocessed.

Description:
Birds were frequently in the the field-of-view and soiling the mirror, affecting the 
visible sky image and resulting processed cloud fraction image. Bird deterant spikes were 
installed on top of the camera housing and arm on 5/16 which prevented their perching on the 
camera so that the impact on the sky image was reduced. But birds were still present 
around the edges of the mirror until additional spikes were installed on top of the four 
corners of the enclosure on 6/14.

TWP/TSI/C1 - rust spots on mirror
DataStreams:twptsiskycoverC1.b1, twptsicldmaskC1.a1
Description:
During the evening of 7/8/2006, something caused several rust spots on one side of the 
hemispheric mirror which continued to grow in size and to be interpreted as clouds in the 
processed images. This problem was corrected during a site visit when the mirror was 
replaced.

Description:
The TT8 control board temperature was high, ~50C, so that the cooling fan was constantly 
on. It appears that the heat sinks were not transferred from the original board to the new

TWP/TSI/C1 - solar shadowband inoperative
DataStreams:twptsiskycoverC1.b1, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskyimageC1.a1
Description:
The mirror/shadowband was not turning and there was no communication with the control 
board. The shadowband was stuck in the position of 0 degrees from 8/29 to 9/20/2006.

On 10/12/2006, the mirror was replaced, the real-time clock chip was removed and heat 
sinks were added to the control board, and the Ethernet hub and serial adaptor were replaced. 
On 1/8/2007, the slip clutch assembly, timing pulley, and timing belt were replaced 
(which were damaged when the mirror was replaced). These actions did not correct the problem. 
The instrument was swapped with the unit from Darwin so that the control board could be 
repaired and tested in Darwin.

Several images were collected in the iterim that should be ignored. These images include 
periods when the sun was not masked by the shadowband or the camera lens was covered by 
tape to protect the CCD from direct
exposure to the sun. There are also extended periods of missing data when the instrument 
was shutdown, waiting for parts.

NIM/TSI/M1 - Shadowband Misalignment
DataStreams:nimtsiskyimageM1.a1, nimtsimovieM1.a1, nimtsicldmaskM1.a1
Description:
From installation, the shadowband was positioned south at solar noon until the vernal 
equinox when it began to migrate counter-clockwise until reaching east 37 days later on 4/26 
(about 9 days before mid-spring). The shadowband at solar noon continued to migrate until 
reaching its most northerly position (~15 deg) on the summer solstice (if everything was 
perfectly aligned, it probably would have been pointed north on this day). It then began 
to migrate clockwise and reached east again 56 days later on 8/16 (about 14 days after 
mid-summer). As expected, the shadowband reached its most southerly position on the 
autumnal equinox but was about 10 deg off of being due south. 

With the apparent alignment problem, I don't understand why the shadowband was mostly 
blocking the sun. When I started noticing this offset in May, I chose to leave it alone 
because I felt that adjusting the shadowband to where I thought it should be would cause it to 
not block the sun at either sunrise or sunset. 

The alignment was corrected on 9/29 (6 days after the day of the autumnal equinox).

NIM/TSI/M1 - Reprocessed and Corrected: Shadowband glare
DataStreams:nimtsiskycoverM1.b1
Description:
DATA REPROCESSED and CORRECTED: 

Due to the high aerosol conditions at Niamey, the TSI appeared to be beyond the limits of 
processing the color JPEG image into cloud fraction values. The processed images indicate 
an opaque sky cover, even in the absence of clouds. The problem was corrected by 
removing the neutral density filter from the lens and re-adjusting the sky filter values.

The data were archived in January 2017. Please retrieve the reprocessed data for use in 
your analysis. 

ORIGINAL DQR CATEGORY: Yellow (Suspect)

REPROCESSED and CORRECTED DATA ARCHIVED:2017-01

REPROCESS IDENTIFICATION NUMBER: RID 313

---------------------------------------------------
--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------

When the neutral density filter was removed from the lens, the reflection of the sun from 
the smooth shadowband strip became much brighter causing a glare in the image on clear 
days. To minimize this reflection, a rough surface (the "fuzzy" side of an adhesive velco 
strip) was placed along the length of the shadowband.

Description:
The mirror was not rotating so the shadowband was not masking the sun. This appears to 
have been caused by snow that was melted by the mirror heater and then re-frozen by high, 
cold winds.

PGH/TSI/M1 - Reprocessing Notice (RID 712)
DataStreams:pghtsimovieM1.a1
Description:
See below for details of reprocessing that was completed on 20150310.  Original DQR 
category: 5 (Transparent - Does not affect quality).

-----------------------------------------------------------

The TSI names the daily tsimovie file with the UTC date in which the sun rises and the 
file begins. At PGH in the summer, the sun rises just before 00:00 (earliest sunrise is at 
23:41) so the daily movie should start and the file be named with the date that is prior 
to much of the remainder of the file. 

The TSI at PGH was set to start automatically each morning at 23:58 UTC but it should have 
been set to start about 20 minutes earlier. Therefore, sky images for the first few 
minutes of each day through 7/19, when the sun began rising after 23:58, were not collected. 

On 8/26, the times of the scheduled tasks were adjusted to those that should have been 
used from the beginning of deployment.

Since only a maximum of three images were collected prior to 00:00 UTC each day, it will 
be less confusing for data users if these images were removed from the daily movie files 
through 7/19. 

Reprocessing has been requested.  In the meantime, the pghtsimovieM1.a1 files have been 
renamed to reflect the date the bulk of the data represents.

MAG/TSI/M1 - Shadowband misalignment
DataStreams:magtsiskyimageM1.a1, magtsiskycoverM1.b1, magtsicldmaskM1.a1
Description:
The mirror was not being controlled correctly so the shadowband did not block the sun 
because the encoder failed. Also, the shadowband was not correctly positioned in the 
processed image while at port because the INS system failed.

On 10/19 while at Long Beach port, the encoder was replaced and software was installed to 
get the mirror control board to receive the SeaNav data and correctly position the 
shadowband to mask the sun in the visible image. However, the position of the shadowband in the 
processed image was not correct because the imaging software needed to be configured to 
independently read the SeaNav information.

On 11/8 while at Honolulu port, the TSI software was upgraded at 17:10 and the position of 
the shadowband in the processed image was corrected. However, because SeaNav failed and 
course-over-ground was being used as a surrogate for heading, the heading is 0 deg when 
the ship speed is < 1 m/s. So the platform heading was changed manually at 17:45 to 
correct the position of the shadowband in the visible image while the ship was in port. 

This method was used by the site technicians to configure the TSI upon arrival and 
departure at port until the ship navigation system was replaced on 12/7 at 9:00. The $TSINV 
heading value became accurate while in port so the position of the TSI shadowband was 
automatically controlled correctly both at sea and at port.

OLI/TSI/M1 - Shadowband Misalignment
DataStreams:olitsiskyimageM1.a1, olitsiskycoverM1.b1, olitsicldmaskM1.a1
Description:
The TSI mirror became loose from the shaft due to high wind. The lens was covered from 5/1 
00:25 to 5/2 22:07 to protect the CCD. The mirror was secured to the shaft on 5/8 and 
TSI Tracker was ran on 5/19 to correct the lat. and lon. and reset the home (north) 
position of the mirror. The lat. was also corrected in TSI Manager on 5/19.

MAG/TSI/M1 - Ship mast in field-of-view
DataStreams:magtsiskycoverM1.b1
Description:
The mast of Horizon Spirit cargo ship was in the field-of-view of the TSI and contributed 
to the calculated fractional sky cover amount (i.e. the ship's mast was interpreted as a 
cloud). This effect is most apparent during clear sky periods and negligible during 
overcast periods.

An algorithm will be developed to remove the contribution of the ship's mast to the 
fractional sky cover determination.

DataStreams:enatsiskycoverC1.b1
Description:
Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt 
instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be 
corrected. The respective GRW and ENA lat, lon, and alt values are as follows:
 
GRW  lat = 39.0911 ;
ENA lat = 39.0916 ;
GRW  lon = -28.0297 ;
ENA  lon = -28.0257 ;
GRW  alt = 26 ;
ENA  alt = 30.48 ;

Description:
The YYYMMDDHHMMSS_tsi.properties files were corrupted when the computer operating system 
was upgraded, causing the ingest to assign incorrect values to attributes opaque_thresh, 
thin_thresh, cam_mir_dist, and center_x. A default properties file from 5/25/2004 was 
briefly used and then a properties file from 10/11/2013 was being concatenated to the current 
properties file before it was moved to the ingest directory, so that the last values 
read were from the earlier date.
