  1. Southern Ocean Studies: NCAR Measurement capabilities and integrating the measurements with the Community Earth System Model (CESM) Jeff Stith, Andrew Gettelman NCAR is sponsored by the National Science Foundation

  2. 10 + Hours Endurance Typical payload 15,000 lb NSF C130: heavy-lift research aircraft • Range 3100nmi • Altitude 26,000 ft

  3. Long-Range (up to ~5000 n miles ) Gulfstream V: A Platform for Global Scale Measurements • High Altitude (up to 51,000 feet) • Up to ~6000 lb payload • Up to 12 hours endurance (10 hours typical) • Six under-wing hardpoints • Up and Down (2) Co-Aligned 20 inch optical viewports • Ample inlets and fuselage hard points

  4. HIAPER Pole-to-Pole (HIPPO) : Global scale research in different seasons Flight Hours: 86 (January 2009) 90 (October 2009) 85 (March 2010) 97 (June 2011) 103 (August 2011) Total Flights: 64 Distance : 171,000 miles Vertical Profiles: 461

  5. Airborne instruments HIAPER Cloud Radar 3VCPI Combination of Radar/lidar with in-situ measurements is very powerful! www.eol.ucar.edu/instrumentation www.eol.ucar.edu/deployment/request-info
