  1. Int’l Collaboration OpportunitiesNASA/JAXA/(CSA) Workshop on the ACE mission29-31 July 2008Kauai, Hawaii

  2. Attendees

  3. Highlights and Recommendations (1) Many activities are underway and proposed in Japan and Canada that might contribute to the ACE mission. Encourage ongoing discussions with JAXA and CSA, and with ESA and CNES.

  4. GCOM satellites Both GCOM-W and GCOM-C are 12-year series of 3 satellites (4 years each) GCOM-W1 AMSR2 (Advanced Microwave Scanning Radiometer 2 follow-on to ADEOS-2) Planned to be launched in Winter, 2012 GCOM-C1 SGLI (Second generation Global Imager) Planned to be launched in 2013 Plan for the 2nd and 3rd generations GCOM-W2 (in 2016), GCOM-W3 (in 2020) GCOM-C1 (in 2017), GCOM-C3 (in 2021)

  5. geophysical and biological pathways of solar light energy shortwave & thermal InfraRed (T) Scanner (IRS) GCOM-C Satellite sensor & data products • 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. Polarization (along-track slant) radiometer (P) Visible & Near infrared push-broom Radiometer (VNR) SGLI : Second generation GLobal Imager Multi-angle obs. for 670nm and 865nm

  6. Research products (land) Standard products (ocean) GCOM-C products Standard products (atmosphere) Research products (ocean) Research products (atmosphere) Research products (cryosphere) Standard products (cryosphere)

  7. GCOM-W1 satellite - will be flown in A-Train GCOM-W (Water) • GCOM-W1/AMSR2 will contribute to long-term observation of global water and energy cycle. • Continue AMSR-E observation (high spatial resolution, low-frequency channels,etc.). • Construct reliable long-term dataset to contribute for understanding and monitoring of climate change. • Contribute to operational use by providing continuous cloud-through SST, frequent and quantitative storm observation to maintain precipitation forecast accuracy.

  8. CSA Mission Studies

  9. Highlights and Recommendations (2-6) • 2. Re-establish/re-invigorate the NASA/JAXA ocean color study group to • a. Study instrument calibration • b. Consider integrated or coordinated programs • Use GLI UV bands to demonstrate ACE capability 3. Develop an interagency (NASA/JAXA) agreement, covering aspects of ACE science, including ocean color and orbit selections, encourage collaborations and exchange of data. • The planned EarthCARE conf in Japan 09 would be a good time to schedule an int’l ACE science workshop to develop advocacy. 5. Distribute updated ACE mission science requirements, as they are discussed and defined in a series of US science community workshops this Fall and next Spring 6. Submm-wave radiometers can bridge radar and lidar measurements • Synergy with operational mm-wave sensors from GPM, GCOM-W, and NPOESS

  10. JEM/SMILES Mission JEM/SMILES: Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) designed to be aboard the Japanese Experiment Module (JEM) on International Space Station (ISS) SMILES is a passive sensor in submillimeter-wave region with super sensitivity. Launch in 2009 summer. Collaboration project of NICTand JAXAto demonstrate superconductive mixer and 4-K mechanical cooler for the submillimeter limb-emission sounding in space and to observe atmospheric minor constituents in the stratosphere. Major Design Parameters • Obs. Freq. : 640 GHz band • Band Width:1200 MHz x 2 • FOV: ～3km • Tsys: 500 K • Mission Life time: 1-2 year Flight Model

  11. Highlights and Recommendations (7) Risk reduction for ACE could be accomplished by a combination of field campaigns and research activities, for example: • a. Use GLI UV observations to demonstrate ACE ocean color capability • b. The US Navy ocean color aircraft program • c. MIRAI shipborne observations • d. Air-MSPI (imaging polarimeter) under development by JPL • e. Airborne HSRL at Langley Research Center • f. Airborne ocean color instrument that could be available around four years from now • g. JPL airborne doppler 94GHz radar and PR-2 • h. June 09 US-DOE field campaign with APS (polarimeter)

  12. Highlights and Recommendations (8-9) • NASA Venture-class missions might fill the gaps between EarthCARE and ACE, and/or a Venture-class mission might be a building block of ACE. These Venture-class missions are good opportunity for partnerships with JAXA, CSA. • A multi-stage, multi-orbit, multi-platform, implementation of ACE was discussed (following slides)
