AMY Data Workshop 2010: agenda and minutes

JAXA data for AMY (Keiji Imaoka / JAXA EORC)

• JAXA operating and planned satellite/missions
  • (operating)
    • TRMM: rainfall (PR, TMI, VIRS): 1997.11.28-
    • Aqua AMSR-E: 2002.05.04-
      • stable (except 89GHz-A lost 2004.11-)
      • includes C-band channel 6.9 GHz ... good for SST, soil moisture
    • Daichi (ALOS): high-res land mapping, 2005-
      • PALSAR, PRISM, AVNIR-2 ~10 m resolution
      • special data policy
    • Ibuki (GOSAT): CO2 profile, 2009-
  • (planned)
    • GCOM-W: water and energy cycle
    • GCOM-C: radiation budget and carbon cycle
• Product categories
  • standard product ... scheduled and operational processing
  • near real time product ... for operational users
  • subset product
  • research product ... not (yet) operational
• Standard products
  • TRMM (well known)
  • AMSR-E standard products
    • water vapor (vertically integrated)
    • cloud liquid water
    • precipitation
    • sea surface temperature
    • sea surface wind speed (scalar)
    • sea ice concentration
    • soil moisture (still difficulty in dense forests)
    • snow depth
• Microwave and Infra-red combined sea surface temperature product by Tohoku Univ. (Kawamura)
• Research products
  • GSMaP ... precipitation from TRMM, microwave imagers, geostationary IR
    • http://sharaku.eorc.jaxa.jp/GSMaP/
    • 1-h interval, 0.1 deg. grid
    • 4 hr after obs.
  • TRMM latent heat
    • http://www.eorc.jaxa.jp/TRMM/lh/index.html
  • JASMES (JAXA satellite monitoring for environmental study)
    • http://kuroshio.eorc.jaxa.jp/JASMES/index.html
    • MODIS-derived geophysical parameters (pre-GCOM-C)
    • PAR, snow cover extent, water stress trend, wild fire, cloud cover rate
    • (based on MODIS 1b, not MODIS standard product)
    • monthly or twice-a-month
  • ALOS K & C (Kyoto and Carbon) Initiative
    • PALSAR mosaic for forest classification, carbon stock estimates
    • http://www.eorc.jaxa.jp/ALOS/kc_mosaic/jkc_map_50.htm 50 m resolution for tropical Asia etc.
    • http://www.eorc.jaxa.jp/ALOS/kc_mosaic/jkc_map_500.htm 500 m resolution global browse
• How to get JAXA's earth observation data
  • See http://www.eorc.jaxa.jp/
    • Look at "Data distribution service" for standard products
    • Look at each of "Research project" for research products (no unified interface yet)
  • Data distribution service ... for standard products (except ALOS and GOSAT)
    • EOC/EOIS (Earth Observation Information System)
  • GOSAT: NIES is responsible for data. See http://data.gosat.nies.go.jp/ .
• CEOP Satellite Data Gateway
  • http://www.ceop.net/
  • TRMM, Aqua AMSR-E, some MODIS
  • Spatial
    • 250 km around CEOP reference sites
    • monsoon regional
    • global
  • Temporal
    • CEOP EOP3/4 already available
    • 2007-2009 soon available

Q/A

• Plan to extend TRMM to higher latitudes?
  • GPM to cover up to 60 deg., radar of 2 frequencies to detect snow.
• AMSR-E uses C-band. Plan to use L-band?
  • AMSR-E series for GCOM stick to C-band. L-band will be implemented in American and European missions.
