Clear at takeoff, Dewpoint 15.0, Temperature 22.5 deg C. cloud tops were generally about 2000 ft. quite uniform cloud tops. considerable drizzle observed by radar. fairly uniform, but with more drizzle in NE than SW. Almost solid clouds everywhere. winds mostly from the NW and light-maybe 5 m/s. early in flight, clouds were more cellular, and extended below 500', and perhaps down to near the surface in spots. Later, the cloud layer became more uniform, probably because of enhanced mixing as the solar heating decreased.

|---|---|
| 20:05 | holding at end of runway |
| 20:09 | takeoff |
| 20:21 | clouds scattered. inversion at about 1500' from SABL. |
| 20:37 | up to 18000' for rest of ferry to starting point. |
| 20:43 | I can see an aerosol layer below us, but not much below. |
| 21:22 | start 17500' circle cw at 225 deg. |
| 21:52 | end of 17500 circle & descend at 1000'/min |
| 22:15 | start 1500' circle in cloud. cloud top - 1800-2000' cw starting at 160 deg. cloud base variable from 500' to near sfc. |
| 22:45 | end of cw circle at 1500', turn to ccw and go up 100' |
| 22:47 | start 1600' circle ccw at 340 deg. |
| 23:17 | end of 1600' circle ccw at 340 deg. ascend |
| 23:19 | holding for 1 min at 2200' |
| 23:20 | starting descent. cloud tops 1900' |
| 23:24 | start circle at 500' ccw at 272 deg |
| 23:54 | end of 500' ccw circle at 272 deg |
| 23:55 | start 900' circle ccw at 254 deg. |
| 00:26 | end of 900' circle ccw at 240 deg. descend and ascend to 3000' |
| 00:31 | start 3000' cw circle then ascend to 3500 ft after 2 min. to get lidar return. heading 30 deg. haze layer above us. |
| 01:01 | end of 3500' leg. start descent to porpoising leg at 1700-2200' heading 40 deg cw |
| 01:05 | start porpoising 17600-2200' |
| 01:34 | end of porpoising leg. descend to lowest flight level 070 deg cw |
| 01:37 | start 300' leg at 110 deg cw |
| 02:07 | end of 300 ft leg and ascending to 900ft. 110 deg cw. |
| 02:09 | start 900 ft circle 130 deg cw. clouds more uniform this time. better mixing?
|
| 02:23 | passed through a little wisp of cloud. intermittent patches, but very light. mostly the clouds are uniform |
| 02:25 | heavier cloud. |
| 02:39 | end of 900 ft cw leg at 130 deg |
| 02:43 | start 1600 ft circle cw at 180 deg in cloud |
| 03:13 | end of 1600' leg. turn to ccw and go up to 1700 ft. |
| 03:15 | start 1700 ft ccw at 360 deg |
| 03:38 | end circle at 1700 and do sounding down and then up to 8000 ft. |
| 03:46 | start circle at 8000 ft. ccw at 007 deg. clouds look very uniform. |
| 04:08 | end of 8000' circle - ended at about 60 deg. didn't finish circle. not enough time. ferrying back at 8000 ft. |
| 05:16 | land at NYZ |
