Subject:	SGP/CSPHOT/C1 - Unit #99 removed for upgrade
DataStreams:	sgpcsphotsizeC1.a1
Description:	S/N 99 was returned to Aeronet for calibration/modification at the end of Sept. On return, the upgraded and recalibrated instrument was relocated to be next to the SWS.
Measurements:	sgpcsphotsizeC1.a1: sun_error Column volume size distribution (dV/dlnr)(size) Altitude above mean sea level(alt) zenith time_offset timeObs sky_error North latitude(lat) siz_index num_of_angles last_processing_date East longitude(lon) time base_time tail_level Aerosol optical thickness, from CSPHOT(tau440) alm_type bins Aerosol optical thickness, Angstrom coefficient, from CSPHOT(alpha440_870) tail2 tail1

Subject:	SGP/CSPHOT/C1 - Not Performing Zenith Observations (Cloud Mode)
DataStreams:	sgpcsphotsizeC1.a1
Description:	There were problems associated with the implementation of "cloud mode" on the upgraded CSPHOT system resulting from problems with the programming on the internal EPROM. The "cloud mode" did not work properly and other observations were also affected. For example, early morning sun and almucantar observations were missing. On 4/30/2007, the instrument was re-installed with cloud mode and was verified to be working.
