UTD 200 S: third week

During the last week the UTD team was mainly involved in the calibration of the system and in detection of the sonic anemometer locations over the met-tower. During those operations, the lidar GUI experienced several events of slowing down and freezing. Interacting with Leosphere, a bug was detected in the GUI. Indeed, for each test the lidar uploaded not only the requested scans, but all the scans saved in the hard drive (more than 700!!!), thus creating overload for the RAM and in turns the GUI crash. A fix to this bug is not developed yet, thus the only temporary solution consisted in doing a back up of all the data, then erasing the HD. After this operation, the GUI still freezes sometimes, and in several cases a manual reboot is needed (Thanks Aditya for your help!).

Since last night the UTD 200S is performing 14.5 minute fixed measurements  over the sonic anemometers on the SE booms, elevations 50 m, 100 m, and 150 m. A fixed measurement is also performed over the lidar supersite, elevation 60 m. The measurements are performed with a spatial resolution of 50 m and accumulation time of 500 ms. In the following the schedule running hourly and simultaneously on the UTD 200S, Dalek 1 and 2:

• h:00 SE sonic 50 m height;
• h:15 SE sonic 100 m height;
• h:30 SE sonic 150 m height;
• h:45 lidar supersite 60 m height.
