SGP/CSPHOT/C1 - AOT 1640 channel data missing
DataStreams:sgpcsphotaotC1.a1, sgpcsphotaotfiltC1.a1
Description:
AOT 1640 channel data missing.  The instrument deployed at SGP from September 2008 to July 
2010 was not upgraded with this additional channel.
Measurements:sgpcsphotaotfiltC1.a1:
  • TripletVar_1640
  • Aerosol optical thickness, at 1640 nm, from CSPHOT(aot_1640)
sgpcsphotaotC1.a1:
  • TripletVar_1640
  • Aerosol optical thickness, at 1640 nm, from CSPHOT(aot_1640)

Subject:
TWP/CSPHOT/C2 - 340 nm filter degradation.
DataStreams:twpcsphotaotfiltC2.a1
Description:
There was 340 nm filter degradation in the Nauru Cimel Sunphotometer starting 11/1/2009.  
The 340 AOD was in disagreement with other channels sporadically starting 11/1/2009 and 
consistently off from the other channels by March 2010.  Therefore 340 AOD channel should 
not be used until the unit is replaced.  

The 340 nm filter will be changed when the instrument is sent back for calibration.
Measurements:twpcsphotaotfiltC2.a1:
  • Aerosol optical thickness, angstrom coefficient, at 340-440 nm, from CSPHOT(Angstrom340_440)
  • TripletVar_340
  • Aerosol optical thickness, at 340 nm, from CSPHOT(aot_340)
