TWP/TSI/C1 - obstruction in lens
DataStreams:twptsiC1.00, twptsicldmaskC1.a1, twptsimovieC1.a1, twptsiskycoverC1.b1,
twptsiskyimageC1.a1
Description:
The TSI at Manus has been able to remain dry and produces an image but the percentage of 
cloud cover is determined to be 100% even on cloud free days. Moisture in the camera lens 
and neutral density filter was corrupting the sky images. The lens and filter were 
cleaned, the moisure seals checked, the camera housing sealed, and desiccant added to both the 
camera housing and main electronics enclosure. On 3/23/2006, the lens was replaced and 
the sky images were significantly improved.
