Flight (Mission) Detail by Peter Hobbs
Goals of Flight:
- Climb to 10,000 ft and transit to COVE lighthouse
- Underfly Terra at COVE lighthouse at 100 ft (Terra overpass at 1542 UTC)
- BRDF near COVE lighthouse at 36 degrees 57.3 minutes North and 75 degrees 37.5 minutes West
- BRDF over Dismal Swamp
- Calibrate pressure, temperature, and winds against Wallops special sonde
Accomplishments of Flight:
- Done
- Done (CV-580 at lighthouse at Terra overpass time)
- Done at location slightly offset from prescribed point to avoid cloud
- Cancelled due to clouds over Dismal Swamp
- Done
Weather Conditions:
Clear at take-off except for small cumulus clouds on the horizon. Increasing cumulus clouds during flight, with about 50% cumulus cloud cover over Wallops at end of flight. Low aerosol optical thickness (AOT), about 0.1 from surface.
Instrument Problems:
- Some problems with TANS locking on to satellite (affects pitch and roll angle measurements)
Additional Comments:
- Other aircraft flying: Cessna, Proteus, OV-10

Take off |
| 1440-1504 |
Climb to 10,000 ft on transit to COVE lighthouse |
| 1504-1530 |
Descend at 500 ft/min then 1,000 ft/min to 100 ft |
| 1530-1554 |
Runs at 100 ft over lighthouse. Over lighthouse at Terra overpass time of 1542 UTC. |
| 1554-1559 |
Look for cloud-free spot near designated point for BRDF measurements |
| 1559-1617 |
Seven CAR turns at 600 ft near designated spot |
| 1617-1623 |
Climb to 4,000 ft to talk to CLAMS control. Advised that it was cloudy over Dismal Swamp but to proceed there to inspect visually. |
| 1623-1632 |
Transited part way to Dismal Swamp. In view of considerable cloud in direction of Dismal Swamp, decided to cancel BRDF over swamp |
| 1632-1715 |
Transit back to Wallops |
| 1715-1735 |
Followed special radiosonde launched from Wallops to 12,000 ft for temperature, humidity, and wind comparisons. |
| 1745 |
Touchdown at Wallops |
| 1749 |

Weather Summary by Fred Rose
CREATION DATE: Saturday, 14 July 2001 09:29:15 UTC
FORECAST: Sunny. High in low 80's. Lows in low-mid 60's Norfolk and around 60 Wallops. Lets Fly!
GENERAL OVERVIEW: Surface high pressure system in control with clear skies. Upper level trough axis offshore. Vorticity maximum to the north (in Pennsylvanis) with a few clouds and showers; but not much moisture associated with it.
DISCUSSION: About as good a clear sky day as we can get this time off year. Cumulus may form late in the day over land because of diurnal strong surface heating. A tanning index 10 day!
