2 NOAA’s Mission To describe and predict changes in the Earth’s environment. To conserve and manage the Nation’s coastal and marine resources to ensure sustainable economic opportunities. NESDIS’s Mission To deliver accurate, timely, and reliable satellite observations and integrated products and to provide long-term stewardship for global environmental data in support of the NOAA mission.

3 NESDIS DATA CENTERS NGDC: Understanding Our World NCDC: Understanding Our Climate NODC: Understanding Our Coasts and Oceans Curators of the Nation’s Environmental Data

4 National Oceanographic Data Center NODC Mission : To provide scientific stewardship of national and international marine environmental and ecosystem data and information Ensure that global oceanographic data sets collected at great cost are maintained in a permanent archive that is easily accessible

5 Traditional “Archive” activities just one part of the picture… Monitoring and understanding user communities Monitoring and understanding technology changes Encouraging adoption of standards Submission Agreements Working with providers to create “archive ready” datasets Environmental Data should be Archived What do we mean?

6 Long Term Stewardship and Reanalysis Facility (LTSRF) Acquire GHRSST data –30 days from observation, data processed through GDAC at JPL –Using automated procedures, NODC acquires the data Preserve the GHRSST data assets –NODC processes data into the archive and builds additional metadata Assemble data into easy to use long-term data sets –GHRSST Reanalysis, AVHRR Pathfinder SST, SST Inter-comparison Provide access to GHRSST data for business, federal, and science users –GHRSST continued to increase the number of users in For January – April of 2009, 5173 files per day were transferred on average compared to 1734 in 2008 Describe the environment –Pathfinder data was used in a new study, which shows the extent of harmful human influences on global marine ecosystems (Halpern et al, 2008) NODC Stewardship of GHRSST End-to-End Management of Data Success relies on national and international partnerships

7 NODC Stewardship of SST Data Assemble data for long term use AVHRR Pathfinder SST –Focus on AVHRR sensor series to create the single-sensor SST climate data record –Reprocessing activities for Sea Surface Temperature include extensive quality control and assurance, with focus on climate applications GHRSST Reanalysis –Internationally coordinated effort to integrate all satellite SST sources over the long term GCOS SST Intercomparisons - Satellite, In situ, and blended product intercomparison facility –Understanding satellite and in situ inputs, and resulting analysis/reanalysis products Critically examining data quality from our unique, integrated, and long-term perspective

8 NODC Stewardship of SST Data Provide Access to Data Volumes of GHRSST data accessed at the NODC LTSRF (in gigabytes) The Group for High Resolution Sea Surface Temperature product continued to increase Archive volumes growing from 12.5 terabytes in May of 2008 to 20 terabytes in May of 2009 Calendar year 2009 is on pace to see four-fold increases in terms of both volumes and numbers of files accessed compared to 2008 Volume in gigabytes arriving in the LTSRF each day Number of users of GHRSST data at the NODC LTSRF (based on unique IP addresses) numbers are projected based on Jan-Apr numbers.

9 Success will rely on national and international partnerships Pathfinder data was used in a new study, which shows the extent of harmful human influences on global marine ecosystems (Halpern et al, 2008). NODC provides scientific stewardship for these data. NODC created an online Sea Surface Temperature (SST) framework that provides all of the inter-comparison diagnostic data easily viewable and accessible. These efforts are leading to an enhanced understanding of our changing climate, specifically the critically important parameter of SST NODC Stewardship of SST Data Describe the Environment

10 Scientific Data Stewardship NODC Scientific Data Stewardship Value-added Products Ocean Heat Content – how oceans are warming or cooling in a changing planet Ocean Variability Studies – how are the ocean’s physical and biogeochemical characteristics changing; NOAA’s Coral Reef Information System (CoRIS): Users can search for Coral metadata records in a Google map application Hypoxia Watch 2008 based on data collected from Southeast Area Monitoring and Assessment Program (SEAMAP) Groundfish surveys NCDDC Regional Ecosystem Data Management Portal NODC Ocean Wave Data and Information Portal (OWDIP) provided users with “one stop shopping” for easy access to: 1) NODC archived wave data, 2) NDBC climatic summaries, and 3) NDBC real-time data Putting all our data sources together, to understand today’s environment in the context of the past Warming of the Oceans
