CT Groundtruth Data from February 13th

Data has been received from the "groundtruth" CT that is connected to the station during maintenance trips. As a reminder, the idea is that the CT should be connected to the station for a full hour before cleaning begins, followed by one hour of cleaning, followed by one more hour after cleaning ends. Each "hour" begins and ends at six minutes before the clock hour (i.e., at 9:54am, 10:54am, etc.).

The CT was connected to LPPR1 at about 10:30am on Monday, February 13th (local time). It was removed at about 2:30pm that afternoon. It may be surmised that the "before" hour ran from 10:54am to 11:54am, the "during" hour from 11:54am to 12:54pm, and the "after" hour from 12:54pm to 1:54pm. Data for these three hours is as follows:

Validation and Complete Station Cleaning
The first validation run, couple with a complete cleaning of the sensors and structure was realized yesterday (Tuesday Febraury 13, 2006). The process started at 10:45 am (GMT-4) and completed by 2:20 pm. No problems were found. Three (3) adults Manatees were observed swiming in the surrounding area.
