18 Status of COMS follow on

19 Missions of COMS follow on Continuing the COMS Meteorological Mission ü Planning to be launched in 2017 Improving the Severe Weather Monitoring ü Higher frequency of observation ü Retrieving the atmospheric structure (pseudo sounding) Improving the support of the NWP model ü Efficient data assimilation system Intensifying the environment & climate monitoring ü Various surface information retrieval ü Air pollution monitoring ü Establishing long term observation data 19

20 Development of COMS follow on A conceptual design for twin satellites is proposed in 2009 based on Korea National Plan for Space Development One for the Meteorological Imager follow on(2017), and the other for the Ocean and Atmospheric Trace Gas monitoring(2018) The program will be started in middle of 2011 COMS follow on (2A) COMS follow on (2B) 20

21 COMS follow on payload (I) Meteorological payload COMS COMS Follow on Channels 5 16 Spatial Resolution(km) 1/4(VIS/IR) 0.5,1/2(VIS/IR) Temporal Resolution(min) 25(Full Disk) 15(Full Disk) Level 2 Products 16 ~58 Data Rate(Mbps) 2.6 ~70 Life time(years) 7 10 Main Purpose of use Weather Forecasting + NWP + CM 21

22 COMS follow on payload (II) Sensor for space weather Mass/Power budgets are limited due to the size of satellite (using same size as COMS) Possible to on board : Particle detector, Magnetometer and so on HEPD : (m), 5 (kg) LEPD : (m), 5 (kg) Magnetometer : (m), 10 (kg), 3m(after boom deploy) On going preliminary study for Space weather payload (2011) 22
