2021/03/16 11:00:00 David Delene: During afternoon visit to ICE. We added a new temperature/humidity sensor, which seems to have a better high relative humidity measurement, does not go above 100% like the 3D-PAWS goes, which climbs to 103 %. The new temperature/humidity measurement is available on the Visibility (CS125) dashboard. We also adjusted the height of the Deeplens signs and added new lighting system (light above sign and turn off light on MetTrailer. This provides better fog measurements using the camera. Turn wall heater in trailer back on and set to level 2.

2021/03/04 23:00:00 David Delene: During afternoon visit to ICE. Connect up CPC and CCN counter. Changed the Web camera to use a different USB port, which resulted in better images but some green images on animation, maybe could try go directly to computer instead of USB hub. Got the Ku link to sync, gave valid Wifi on Cradlepoint web site. Left Gopro camera with on UAS. Put rain gauge on 3D-PAWS.

2021/03/04 13:27:28 David Delene: Overnight trailer temperatures good at between 65-70 F. Overnight the visibility only decreased to 30 km (18 mi). The overnight low temperature was -1.5 C. Relativity humidity high was 92 %. Wind speed decreased to 1.5 m/s. The RAMSDIS indicated fog stayed to the south and west, but is forecasting fog for Friday morning. Issues - Deeplens time should be changed from local time to UTC. The 3D-PAWS wind speed not working, but have the Sonic, 3D-PAWS having issues yesterday on reboot so plan not to address at this point.

2021/03/04 8:32:00 David Delene: “No Go” for operation for this morning. No indication of fog at field site. Looks like fog will stay away from site this morning.

2021/03/03 19:00:00 Michael Willette: Returned to ICE during afternoon. Calibrated wind sonic anemometer to correctly indicate wind direction. Updated code for the visibility sensor to prevent complete shutdown of data when there is network/wifi issues. Cleaned web cameras, though one is still whitewashed. Tested burning hygroscopic and small AgI flares using the pully system. Added modifications to pully system to prevent flares burning too close to the tower. Ran into issues restarting raspberry pie, not uploading complete desktop with no mouse/keyboard functionality. Eventually worked after 15(ish) times of restarting.
