  2. ILAS-II onboard the ADEOS-II

  3. Main Characteristics of ADEOS-II

  4. Configuration of ILAS-II

  5. Measurement Species of ILAS-IIVertical profiles (ILAS-II: solar occultation sensor) in polar regions (ADEOS-II: sun-synchronous polar orbit) • Standard Product: O3, HNO3, NO2, N2O, CH4, H2O, aerosol(vis.) • Research Product: ClONO2, N2O5, CFC-12, CFC-11, CO, C2H6, OCS, NO, O3(isotope), aerosol(IR), temperature, pressure The following simulated latitudes and local times of the ILAS-II measurements were calculated for the initial condition of ADEOS-II orbit elements on 1 November 2001 available from NASDA: The general feature is the same irrespective of specific years.

  6. Long Term Plan of Balloon Experimentsfor ILAS-II Validation (Kiruna) • No. 1: FY 2003 (TBD) CLD 1, SAKURA 2, MkIV 1, MIPAS 1, daily ozonesondes • No. 2: August-September 2005 (TBD) CLD 2, SAKURA 2, other flights, daily ozonesondes • No. 3: November-December 2007 (TBD) CLD 2, SAKURA 2, other flights, daily ozonesondes Other satellites: Envisat, SAGE III, POAM III, Odin, ACE, EOS-Aura

Optical ozonesonde (up to 45 km) 5 • 2004 KC (Meisei) 24 May-Jul., Nov.-Feb. • 2005 KC (Meisei) 24 May-Jul., Nov.-Feb. 2) Aerosol particle counter • 2003 2 Jan.-Feb. • 2005 2 TBD • 2007 2 TBD 3) Cryogenic sampler • 2003 Dec. - 2004 Jan. 1 or 2

  8. Launch of ADEOS-II and On-orbit Check Out Plan • Launch of ADEOS-II: Between 10:31-10:47 JST (Japan Standard Time) on Saturday 14 December 2002 Date window: 14-30 December 2002 Note: The followings will be fixed after the launch. • Initial Check Out of ILAS-II: 19-22 January 2003 • *Early Turn On of ILAS-II: 11, 14, 18, 21 February 2003 • *System Total #1: 23-26 March 2003 • *System Total #2 (Start of routine operation of all sensors): 2 April 2003 *ILAS-II measurements over Kiruna will be done.

  9. ADEOS-II ON-ORBIT CHECK OUT PLAN sent from NASDA The launch date is 14 December 2002

  13. ILAS-II Validation Calendar • ILAS-II occultation measurements over Kiruna (67.88N, 21.06E) are calculated. • ILAS-II occultation measurement location depends on an orbit parameter of ADEOS-II, i.e., local suntime of descending of the equator crossing of ADEOS-II, which should be set as 10:30 am +/- 15 minutes. • A set of the following validation calendar information was calculated for the initial condition of ADEOS-II orbit elements on 1 November 2001 available from NASDA: The general feature is the same irrespective of specific years.
