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.
Suggestions: 
Collected data are probably usable, but large periods of missing data are not recoverable.
