Title: Japanese perspective on GIIPSY


1
Japanese perspective on GIIPSY Jinro Ukita (Chiba
University)
ALOS (Advanced Land Observation System) provides
timely contribution from Japan to GIIPSY,
launched on Jan 24 2006 for 3-5 yr mission and
just became operational with three sensors PRISM
Panchromatic radiometer (0.52-0.77mm) with 2.5
m resolution and 75km/35km (nadir/triplet only)
swath for digital surface mapping AVNIR-2
Advanced visible and near IR radiometers in 4
bands (0.42-0.89mm) with 10m resolution and 75km
swath PALSAR L-band SAR with 7-44m, 14-88m and
100m resolution (single, dual, polarimatric)
and 40-70km and 250-350km (single and ScanSAR)
swath in 4 sensor modes

Summary table for PALSAR default modes
Mode Name Pol Off-nadir angle Pass Coverage Period Obs frequency
Fine beam Single HH 34.3 Ascend. Global Dec-Feb 1-2 per yr
Fine beam Dual HH, HV 34.3 Ascend. Global May-Sep 1-4 per yr
Fine beam Polari- matric 21.5 Ascend. Regional Mar-May 2 per 2yr
ScanSAR Single HH 20.1-36.5 Descend. Global Thru yr 1 per yr
ScanSAR Single HH 20.1-36.5 Descend. Regional Thru yr 8 per yr

  • Possible issues to discuss and action items
  • Ways to make requests and feedback from the
    GIIPSY community to JAXA established channel
    through the current PIs?
  • Maybe speak up for un-assigned mode
  • Boundary regions, e.g. 60 deg N
  • Arctic Ocean
  • IPY Legacy (e.g. Greenland during Cycle 26-7)
  • Current PIs and future AOs (2nd AO with Feb 15
    deadline but only for ALOS Data Node Asia/Russia)
  • Lack and absence of direct involvement by
    Japanese scientists
  • The IPY provides an opportunity to build remote
    sensing cryosphere obs community in Japan for the
    benefits of GIIPSY and beyond so what to do?
