Altitude 15.8 km (52 kft) [13.7 km (45 kft)] Endurance, max. 30+ hours [20 hours] Internal payload 300 kg (660 lbs.) [140 kg, 300 lbs.] Total weight 1361 kg (3000 lbs.) Engine Honeywell turboprop (TPE 331-10T) Typical speed 150 – 200 kts (77 – 103 m/s or 172 – 230 mph) Max Distance 10000 km [2700 - 3600 nm (5000 - 6640 km)] Unpressurized and no temperature control in payload bay

3. NOAA UAS Demo Payload GC/OZ (Elkins/Oltmans) Ocean Color (Churnside) Passive Microwave Vertical Sounder (PMVS) H 2 O, temp (Klein) Mapping, Digital Camera System-DCS (Sellars) Marine Sanctuaries, Skyball- EO/IR (Jacob) Flight Planning (Rosenlof, Ray) Project Scientists (Fahey, Gasiewski) Project Managers (Aslaksen, Summers) NASA coordinator (Jennison)

4. 1.Box weighs 22 kg (48 lbs.), 24.6 x 40.6 x 45.7 cm (9.7x16x18.1”), 45.6 liters 2.Measures O 3 once every 10 seconds (commercial unit 2B,Inc.) 3.Measures N 2 O, SF 6, CFC-11, CFC-12, halon-1211 once every 70 seconds. On board calibration. 3.In the future, could measure( PAN, PPN) or (CO, H 2, CH 4 ) for tropospheric mission. Compounds in red are measured by Aura Satellite Instruments. NOAA/CMDL UAS Chromatograph for Atmospheric Trace Species (UCATS)

5. Update Eight successful flights (test) UCATS (GC/OZ) worked on all flights Problems with Ku band modem forced two postponements. Return to flight in October/November 2005 8-10 hour test flight over the ocean planned in early Oct. Two flights planned (1) 20- hour to Trinidad Head, California, and (2) 6-hour fight over Channel Islands NASA planning a UAV flight in 2007 NOAA Administrator VADM Lautenbacher during Media Day at GA Gray Butte, CA on 20 April 2005.
