Relevant NASA/IPY Research and Data System
Activities (1)

• Cyrospheric Science 07 (Closed 8-16-07) NASA's
  Earth Science Research Program places emphasis on
  the productive interaction between activities
  related to observations, modeling, and to field
  campaigns, including those funded under the
  International Polar Year (IPY).
• An additional ice sheet modeling underway through
  NASAs modeling program - Don Anderson.
• NASAs ACCESS Solicitation - focuses on the
  access and use of key environmental data.
• DADDI/CSU awarded in 2005 as a focal project for
  an IPY data portal.
• An additional project 2007 to support Greenland
  research with easy access to data from MODIS and
  AVHRR, AMSR-E and SSM/I, GLAS and ATM, CERES, and
  QuikSCAT.
• Other data technologies are being funded with
  clear applicability to IPY (RSS, subsetting
  services, etc.).
• Decadal Survey Initial Science Panels Held (first
  4 missions) - CLARREO, SMAP, ICESat-II, and
  DESDynI. Reports from these science meetings are
  forthcoming.

Relevant NASA/IPY Research and Data System
Activities (2)

• Landsat Image Mosaic of Antarctica (LIMA) -
  USGS/NASA/NSF/BAS
• The map provides a realistic look at the
  continent in 10 times greater detail than ever
  before and offers the most geographically
  accurate, true-color and high-resolution views of
  the continent possible.
• The mosaic is made up of 1,100 Landsat 7 images,
  captured between 1999 and 2001. The masaic
  contains virtually no gaps in the landscape,
  other than an area at the South Pole, and shows
  virtually no seams between images.
• The Landsat Image Mosaic of Antarctica is now
  available in multiple formats on the Web at
  http//lima.usgs.gov/

Relevant NASA/IPY Research and Data System
Activities (3)

• Pine Island Glacier Project - NASA/NSF
• Pine Island is a highly interesting area in
  Antarctica where rapid changes in glacial ice
  need to be studied.
• The project is a combined satellite and ground
  campaign effort. Data collection will also
  involve extensive aircraft acquisitions.
• Data collected from this effort will be made
  available for research and to the general public.

Relevant NASA/IPY Research and Data System
Activities (Metadata and Data Discovery for IPY)

• Global Change Master Directory (GCMD)
  (http//gcmd.nasa.gov)
• Provides a catalog ad portal for data discovery
  of NASA and other publicly available
  environmental data and services.
• The GCMD is working with IPY and has established
  a dedicated IPY data portal. This portal has
  instances of metadata specific to IPY research
  and geographic areas of interest.
• Continued coordination with other IPY data
  portals is necessary to leverage the services
  that GCMD can provide.
• the STG is a consistent approach to providing
  the polar remote sensing data. perhaps provide
  simple metadata sharing, which could be through
  the GCMD (or DADDI) (M. Parsons)
• ECHO (EOS Clearing House)
• Provides a data granule-level metadata for all
  NASA EOS data.
• ECHO enables common searches of IPY relevant data
  across all NASA on-line data access systems.
• XML-based structure allows more easy mapping
  between differing metadata formats.

Relevant NASA/IPY Ongoing Issues/Feedback to STG

• RADARSAT 1 MOU Continuation - CSA, NASA, NOAA0 is
  only through March 2008 (RADRSAT-2 becomes
  operational). NASA has no plans to purchase
  RADRSAT-2 data.
• ALOS through TDRS Project - NASA/JAXA
• An experimental test to take place in late May
  2008.
• The PALSAR is the instrument of specific NASA
  interest.
• This is Ka-band downlink, now ALOS only uses the
  one JAXA DRTS. Using ground stations via X-band,
  the data is at 1/2 the bit rate, so either lower
  resolution or 1/2 swath.
• If the test project is successful, there will be
  a political decision point of NASA and JAXA on
  whether and what kind of operations using TDRS we
  would like to agree to.
• Craig Dobson is the HQ POC, (Seelye Martin a good
  person at HQ for IPY), for them to send wish-list
  type ideas for PALSAR to.
