  1. Ocean Productivity and Export Flux Data derived from satellite: Biomass (concentration, type) Temperature Light Winds Eddies Sea Ice Data requiring models Mixed layer Grazing Sinking and advection of POC/DOC There is a large list of non-NASA missions for key data types above. Issues are calibration, validation, data availability, tool for using data, integration of data with models, etc.

  2. Drake Passage: Ice concentration vs Chl-a Ice measured by SSM/I-F13 Bootstraps algorithm, Chl: SPGANT using SeaWiFS Ice concentration is mean for squares 1-3 (next slide), Chl-SPGANT is mean for squares 1-4 (next slide)

  4. High Resolution AMSR-E 89 GHz Sea Ice • http://iup.physik.uni-bremen.de/iuppage/psa/2001/amsrop.html • Daily sea ice maps are provided by a small group at University of Bremen using data from JAXAs AMSR-E sensor on NASA's Aqua Satellite  (since May, 2002) . • The main problem is data access and usability: • NSIDC may have all the best data but it is hard to find. • The differences between NASA group and the bootstraps algorithms are confusing • The University of Bremen group provides easy to use HDF data of a single variable: ice concentration. • The NSIDC AMSR-E datasets have 64 (!) different products, including ice concentration but at lower spatial resolution.

  5. 1. Mission Concept of GCOM and SGLI • 1.1 Mission target • Global Climate Observation Mission (GCOM) GCOM-W (water) satellite series #1~3 (Jan. 2012~, 13 years) Sensor: AMSR-2 which is a follow-on sensor of AMSR-E on Aqua GCOM-C (climate) satellite series #1~3 (early 2014 (TBD) ~, 13 years) Sensor: Second-generation Global Imager (SGLI) which is a radiometer of 380-12000nm, 250m-1km resolution, and 1150-1400km swath, as a follow-on mission of ADEOS-II/GLI. • Targets of GCOM-C are followings. • Establishment of long-term observation system for the global carbon cycle and radiation budget • Integrated use withother earth observation systems • Contribution to numerical climate models (driving force, outputs comparison, and parameter tuning) • Contribution to operational use (weather forecast, monitoring of meteorological disaster, fishery..) • Enhancement of new satellite data usability

  8. 2. GCOM-C products and SGLI design - 2.7 GCOM-C/SGLI design radiation budget & primary production shortwave & thermal InfraRed (T) Scanner (IRS) Polarization (along-track slant) radiometer (P) • Targets are carbon cycle and radiation budget relating to the global environmental change. • SGLI’ll observe aerosols, cloud, vegetation, ocean color, sea/land surface temperature, snow/ice, and so on for more than 13 years. • The SGLI features are finer spatial resolution (250m (VNI) and 500m (T)) and polarization/along-track slant view channels (P), which will improve land, coastal, and aerosol observations.

GCOM-C Project Timeline- 4.1 GCOM-C algorithm development and validation schedule (TBD) TBD TBD PFM BBM EM • Evaluate & improve candidate algorithm performance (theoretical performance + processing stability) • Obtain in-situ data, develop and validate algorithms, and examine applications • Pre-launch algorithm implementation-1 (PLI-1) for checking the algorithm theoretical performance and satellite data applicability based on the above results. • Correspond to the satellite sensor design and performance tests. • Examination of the implementability of new algorithms, and improvement of the existing algorithms • Develop using other satellite or in-situ observations • Correspond to the sensor design results. • Intensive verification and improvement for Ver.1 data release as an initial validation phase for about one year after the launch • Validate and improve (version up) algorithms using SGLI observation data • Obtain in-situ data required for algorithm development, validation and improvement • develop and validate research/new algorithms, and develop new usage of the products • Based on the PLI-1 results, improve the at-launch version of operational codes • Pre-launch implementation-2 (PLI-2) for checking flow and performance of the real processing

  13. Geostationary Ocean Color Imager (GOCI) in KOREA - is scheduled to be launched onboard Communication Ocean & Meteorological Satellite (COMS) in June 2009. – Detecting short term biophysical phenomena requires high frequency observation. – Conventional PO satellite hardly observe the ocean color with high frequency. – Reducing cloud problem in OC sensor. * The altitude of GEO satellite is 35,786km * Polar sun synchronous orbit : ~780km Courtesy of Ahn (2008), report to IOCCG 13th meeting
