SGP/TSI/C1 - sampling rate change
DataStreams:sgptsiskycoverC1.a1, 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.a1, 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/TSI/C1 - Heater problem
DataStreams:sgptsicldmaskC1.a1, sgptsiskycoverC1.b1, sgptsiskyimageC1.a1

The TSI was converted from a model 880 to 660 which requires separate power for the mirror 
heater. The heater was not powered during this period so morning dew and other

SGP/TSI/C1 - Birds obstructing view
DataStreams:sgptsicldmaskC1.a1, sgptsimovieC1.a1, sgptsiskyimageC1.a1
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.
