Description:
WEATHER LOGS FOR TLCV - 1997

The following logs are for September 15 - December 31 , 1997.  Each day is
divided into 3 approximately equal intervals and given a simple description 
of sky conditions within the TLCV field of view.  These descriptions are
intended to be used as a search tool for selecting Time Lapse Cloud Video 
(TLCV) images and not to provide cloud classifications.  For classifications, 
visit the SGP weather logs.  These simple descriptions are the following:

Clear (Clr): Essentially cloud free.
Mostly Clear (MClr): A few clouds are evident, but generally cloud free.
Scattered Clouds (Scat): Clouds are present, but generally not too persistent
                         or dense.
Partly Cloudy (Pcldy): Similar to Scattered Clouds but generally more dense 
                       or persistent.
Mostly Cloudy (Mcldy): Heavier clouds throughout much of the interval.
Cloudy (Cldy): Fairly dense cloud cover.

Explanation of notes:

Note #1 : The recording system began suffering tracking problems on occasion; 
this resulted in picture breakup that is apparent in the compressed video.

Note #2 : Condensation within the optical dome.

Note #3 : Early in the TLCV deployment the automatic white balance of the 
camera was defaulted to 'on' after power dropouts; this was corrected in 
Feb 1998, but before this sometimes resulted in excessively green or grey 
video.

Note #4 : Early in the TLCV deployment the z-axis stage positioner allowed 
the camera to slip down slightly within the TLCV enclosure due to wind

Description:
WEATHER LOGS FOR TLCV - 1998


The following TLCV weather logs are for 1998.  Each day is divided into 3 
approximately equal intervals and given a simple description of sky conditions
as viewed within the TLCV field of view.  
These descriptions are intended to be used as a search tool for selecting Time
 Lapse Cloud Video (TLCV) images and not to provide cloud classifications.  
For classifications, visit the SGP weather logs.  These simple descriptions 
are the following:

Clear (Clr): Essentially cloud free.
Mostly Clear (MClr): A few clouds are evident, but generally cloud free.
Scattered Clouds (Scat): Clouds are present, but generally not too persistent
                         or dense.
Partly Cloudy (Pcldy): Similar to Scattered Clouds but generally more dense 
                       or persistent.
Mostly Cloudy (Mcldy): Heavier clouds throughout much of the interval.
Cloudy (Cldy): Fairly dense cloud cover.


Explanation of notes:

Note #1 : The recording system began suffering tracking problems on occasion; 
this resulted in picture breakup that is apparent in the compressed video.

Note #2 : Condensation within the optical dome.

Note #3 : Early in the TLCV deployment the automatic white balance of the 
camera was defaulted to 'on' after power dropouts; this was corrected in 
Feb 1998, but before this sometimes resulted in excessively green or grey video.

Note #4 : Early in the TLCV deployment the z-axis stage positioner allowed the
camera to slip down slightly within the TLCV enclosure due to wind buffeting.
This caused the rim of the glass dome through which the camera views to come 
into the TLCV field of view near the edges of the image.


Note #5 : During the course of a year, the shadowband must be reset occasionally; 
this note indicates that the positioning is slightly incorrect.

Description:
WEATHER LOGS FOR TLCV - 1999

The following logs are for January 01 - December 31 , 1999.  Each day is 
divided into 3 approximately equal intervals and given a simple description 
of sky conditions within the TLCV field of view.  These descriptions are 
intended to be used as a search tool for selecting Time Lapse Cloud Video 
(TLCV) images and not to provide cloud classifications.  For classifications, 
visit the SGP weather logs.  These simple descriptions are the following:

Clear (Clr): Essentially cloud free.
Mostly Clear (MClr): A few clouds are evident, but generally cloud free.
Scattered Clouds (Scat): Clouds are present, but generally not too persistent 
                         or dense.
Partly Cloudy (Pcldy): Similar to Scattered Clouds but generally more dense 
                       or persistent.
Mostly Cloudy (Mcldy): Heavier clouds throughout much of the interval.
Cloudy (Cldy): Fairly dense cloud cover.


Explanation of notes:
Note #1 : The recording system began suffering tracking problems on occasion; 
this resulted in picture breakup that is apparent in the compressed video.

Note #2 : Condensation within the optical dome.

Note #3 : Early in the TLCV deployment the automatic white balance of the 
camera was defaulted to 'on' after power dropouts; this was corrected in Feb 
1998, but before this sometimes resulted in excessively green or grey video.

Note #4 : Early in the TLCV deployment the z-axis stage positioner allowed the
camera to slip down slightly within the TLCV enclosure due to wind buffeting. 
This caused the rim of the glass dome through which the camera views to come 
into the TLCV field of view near the edges of the image.

Note #5 : During the course of a year, the shadowband must be reset occasionally; 
this note indicates that the positioning is slightly incorrect.

Description:
WEATHER LOGS FOR TLCV - 2000

The following logs are for January 01 - December 31 , 2000.  Each day is divided 
into 3 approximately equal intervals and given a simple description of sky 
conditions within the TLCV field of view.  These descriptions are intended to 
be used as a search tool for selecting Time Lapse Cloud Video (TLCV) images 
and not to provide cloud classifications.  For classifications, visit the SGP 
weather logs.  These simple descriptions are the following:

Clear (Clr): Essentially cloud free.
Mostly Clear (MClr): A few clouds are evident, but generally cloud free.
Scattered Clouds (Scat): Clouds are present, but generally not too persistent 
                         or dense.
Partly Cloudy (Pcldy): Similar to Scattered Clouds but generally more dense or
                       persistent.
Mostly Cloudy (Mcldy): Heavier clouds throughout much of the interval.
Cloudy (Cldy): Fairly dense cloud cover.

Explanation of notes:

Note #1 : The recording system began suffering tracking problems on occasion; 
this resulted in picture breakup that is apparent in the compressed video.

Note #2 : Condensation within the optical dome.

Note #3 : Early in the TLCV deployment the automatic white balance of the 
camera was defaulted to 'on' after power dropouts; this was corrected in Feb 
1998, but before this sometimes resulted in excessively green or grey video.

Note #4 : Early in the TLCV deployment the z-axis stage positioner allowed the
camera to slip down slightly within the TLCV enclosure due to wind buffeting. 
This caused the rim of the glass dome through which the camera views to come 
into the TLCV field of view near the edges of the image.

Note #5 : During the course of a year, the shadowband must be reset occasionally; 
this note indicates that the positioning is slightly incorrect.

Final Note: beginning in August, 2000, a slight 'banding' within the images 
becomes apparent; this is quite mild early on and becomes somewhat more 
bothersome as the year proceeds.  For unexplained reasons, this appears to 
have corrected itself at the beginning of 2001.

SGP/TSI/C1 - sampling rate change
DataStreams:sgptsiskycoverC1.b1
Description:
SGP TSI-880 sampling rate changed from 20-second to
30-second at 20020426.001900 UTC (20020425.1819 SGP
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.

SGP/TSI/C1 - Metadata Errors in NetCDF Header
DataStreams:sgptsiskycoverC1.b1
Description:
The value of "sample_int" reported in the netCDF header is
incorrect.  The correct sampling interval is 30 seconds.

The maximum values for the variable "sunny" is incorrect.  
It should be 1, not 100 as documented in the netCDF header. 
Users should disregard the "qc_sunny" flag during this
period of time and apply their own qc check if desired.

The minimum value for the variable "solar.altitude" is
incorrect. It should be -90, not 10 as documented in the
netCDF header.  Users should disregard the "qc_solar.altitude"
flag during this period of time and apply their own qc check
if desired.

SGP/TLCV/C1 - Overview of Data Quality
DataStreams:sgptlcvC1.c1
Description:
WEATHER LOGS FOR TLCV - 2001

The following logs are for January 1 - September 14, 2001.  Each day is
divided into 3 approximately equal intervals and given a simple description 
of sky conditions within the TLCV field of view.  These descriptions are
intended to be used as a search tool for selecting Time Lapse Cloud Video 
(TLCV) images and not to provide cloud classifications.  For classifications, 
visit the SGP weather logs.  These simple descriptions are the following:

Clear (Clr): Essentially cloud free.
Mostly Clear (MClr): A few clouds are evident, but generally cloud free.
Scattered Clouds (Scat): Clouds are present, but generally not too persistent or dense.

Mostly Cloudy (Mcldy): Heavier clouds throughout much of the interval.
Cloudy (Cldy): Fairly dense cloud cover.

Explanation of notes:

Note #1 : The recording system began suffering tracking problems on occasion; 
this resulted in picture breakup that is apparent in the compressed video.

Note #2 : Condensation within the optical dome.

Note #3 : Early in the TLCV deployment the automatic white balance of the 
camera was defaulted to 'on' after power dropouts; this was corrected in 
Feb 1998, but before this sometimes resulted in excessively green or grey 
video.

Note #4 : Early in the TLCV deployment the z-axis stage positioner allowed 
the camera to slip down slightly within the TLCV enclosure due to wind 

Note #5 : During the course of a year, the shadowband must be reset
occasionally; this note indicates that the positioning is slightly incorrect.

During the late summer of 2000, a longer term problem arose that caused some
degree of 'banding' across the image.  This problem lasted until Jan 13, 2001
at which time it miraculously disappeared.

SGP/SIRS/E13 - Adjust Direct Normal Irradiance
DataStreams:sgp15swfanalsirs1longE13.c1
Description:
Direct normal broadband shortwave irradiance measured by NIP s/n 30585E6 was found to have 
a 1.76% negative bias when compared in-situ with absolute cavity radiometer measurements 
taken on August 21, 2000.  The estimated measurement uncertainty of the calibration of 
NIP s/n 30585E6 on July 18, 2000 was -2.2% to +2.8%.  

Data from NIP s/n 30585E6 can be adjusted according to the in-situ comparisons to reduce 
the apparent measurement bias.

Description:
The long name attribute for the cloud effect fields incorrectly
defines the cloud effect to be the difference between the 
clearskyfit and measured values:
   
"Difference: ***fluxdn_clearskyfit - ***fluxdn_measured (***fcg)" ;
   
The cloud effects are correctly calculated by subtracting the
irradiance calculated in the clear sky fit from the measured 
irradiance.
   
"Difference: ***fluxdn_measured - ***fluxdn_clearskyfit (***fcg)" ;
   
NOTE: this is just a documentation error.  The data are correctly
calculated.

DataStreams:sgptsiskycoverC1.b1
Description:
A persistent bird was landing on and polluting the mirror, multiple times throughout the 
day. Spikes were placed on the corners and top of the instrument (an affective deterrent 
in the past) but this bird had the agility to perch on the top-center of the mirror.

SGP/TSI/C1 - Reprocess: Corrupt properties file
DataStreams:sgptsiskycoverC1.b1
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.
