Subject:	TWP/CSPHOT/C2 - Battery Voltage Problem
DataStreams:	twpcsphotaotC2.a1, twpcsphotaotfiltC2.a1
Description:	The Cimel Internal Battery Voltage dropped below 5.0 V. This caused satellite data transmissions to failed. Therefore data are very sporadic during this time. Collected data are probably usable. The problem was aleviated for a two months period in Apr./May 2006, when the battery was replaced on or about 2006-03-27. The problem recurred in June because the solar panels were corroded and unable to keep the battery charged. The whole unit was replaced in Nov. 2006 and power is now provided by the site and data are transmitted via land-line.
