  4. ARM TWP Sites

  5. Manus MJO Signal

  6. AMIE and CINDY Sites CINDY2011/DYNAMO AMIE

  7. ARM Modeling Paradigm • Single Column and Cloud Resolving models need context • ARM has developed Variational Analysis data product for this • Typically required surrounding the domain with sonde launches • Not practical/possible for ARM TWP equatorial sites • TWP-ICE showed the powerful constraint afforded by C-POL precipitation information

  8. Original Proposal • Oct. 2010 – March 2011 • Field the SMART-R C-POL radar on Manus • Increase sonde launches • Used in conjunction with ECMWF reanalysis • Produce Variational Analysis product • SMART-R deployment major cost of the proposal

  9. “Stimulating” news! • American Recovery and Reinvestment Act (ARRA) • C-POL on Manus! • Scanning dual-channel cloud radar • Surface LH/SH flux system 6 km All must be in place within 18 months from ARRA announcement!

  10. New Scientific Synergy • Pushed back AMIE one year • Now Oct/Nov 2011 – March 2012 • Moved to coincide with CINDY2011/DYNAMO • Will allow study of initiation and propagation/evolution of the MJO

  11. Synergy • Surface latent/sensible heat flux Manus • Models show decrease in MJO as it propagates through maritime continent • One hypothesis is the difference in land/ocean surface/atmosphere energy exchange • Manus forest tower to represent land? • TAO array (buoys) for ocean

  12. AMIE Design • Launch 8 sondes/day for duration • Better capture the vertical evolution • Add profiling microwave radiometer to interpolate sonde profiles through time • Deploy small system at Navy Base • study small scale variability • Take advantage of C-POL, scanning cloud radar, flux measurements, etc. Questions?
