  2. 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 NASA’s modeling program - Don Anderson. • NASA’s 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.

  3. 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/

  4. 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. NASA contact for Pine Island Project: Seelye Martin, NASA HQ

  5. 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.

  6. - Over 17,000 metadata records - Over 1,000 worldwide data providers - Average 5 million visits per month http://gcmd.nasa.gov/

  7. NASA Earth Science Interoperable Data Architecture

  8. 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.
