NASA Agency Portfolio Update for IPY STG Francis Lindsay, Ph. D Earth Science Division Science Mission Directorate NASA Headquarters SCIENCE MISSION DIRECTORATE
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 Quik. SCAT. – 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 DESDyn. I. Reports from these science meetings are forthcoming. SCIENCE MISSION DIRECTORATE
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/ SCIENCE MISSION DIRECTORATE
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, NOAA 0 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.
