Happy 5 th Birthday Formosat-3/COSMIC! 5 th F3-COSMIC Workshop Rick Anthes 13 April 2011 Assembly of six COSMIC microsatellites at NSPO January 2006

Acknowledgments NSF Taiwan’s NSPO and NSC NASA/JPL, NOAA, USAF, ONR, NRL Special thanks to Taiwan’s leaders, scientists and engineers. Without Taiwan’s support none of this would have been possible!

COSMIC: Major Accomplishments: COSMIC data routinely used in all major global operational centers; significant positive impacts demonstrated in global NWP. Significant impacts on the analysis and prediction of typhoons, atmospheric rivers, Mei-Yu system, heavy rainfall events…. Calibrate AMSU, SSM/I, AIRS, and radiosonde measurements. Study diurnal tide, stratospheric sudden warming, QBO, stratospheric-tropospheric interaction, Kelvin waves, gravity waves, … Drive space-weather assimilation and forecast systems. Study ionospheric events and phenomena (e.g., Wendell Sea anomaly) Approximately 100 papers per year being published, world-wide. Lei et al. (2007), HAO From H. Liu, J. Anderson, C. Snyder Actual Storm With COSMIC No COSMIC

OPAC 2010 Rick Anthes Characteristics of GPS RO Data Limb sounding geometry complementary to ground and space nadir viewing instruments Global coverage Profiles ionosphere, stratosphere and troposphere Only observing system from space that can profile the ABL High accuracy (equivalent to <1 K; average accuracy <0.1 K) High precision ( K) High vertical resolution (0.1 km near surface – 1 km tropopause) Only system from space to observe atmospheric boundary layer All weather-minimally affected by aerosols, clouds or precipitation Independent height and pressure Requires no first guess sounding No calibration required Independent of processing center Independent of mission No instrument drift No satellite-to-satellite bias Compact sensor, low power, low cost Complements IR and microwave sounders Calibrates and reduces biases of IR and microwave sounders All of these characteristics have been demonstrated in peer-reviewed literature

Brief History of FORMOSAT-3/COSMIC July 1965 Mariner IV mission to Mars ~1988 JPL proposes RO mission for Earth 1993 UCAR GPS/MET proposal to NSF UCAR GPS/MET-1 st Earth RO mission 1996 Concept of ROCSAT-3/COSMIC originated in Taiwan (UCAR and NSC) 1997 First tech support agreement NSPO 2001 FORMOSAT-3/COSMIC project begins 2006 Launch April 14, th Anniversary of Launch (today!) But the real history is people……..
