During the flight, thicker aerosols were observed in the lowest 1.5 km. A full moon was also present. These conditions cause some minor degradation of upper level return in the ground based lidar systems.
At the daily science telecon, the date for submission of revised data sets was proposed to be Feb 15. Arrangements will be made to hold an AFWEX breakout meeting at the ARM Science Team Meeting in March.
At mid-day, mid and high level clouds associated with a shortwave from the southeast were passing through central Oklahoma, with an expectation of clearing by 6pm-ish. Also expecting a ~6 hour window of clear before cirrus arriving from northeast. My mid-afternoon, conditions across northern Oklahoma became mostly clear. Conditions remained mostly clear til the end of the flight when some light cirrus moved in from the northwest.
