GDAC overview

GHRSST GDAC homepage Reformatted for common look and feel Forum to be added for project wide collaborations and user support
5
Recent GDAC Accomplishments New data streams added since 2006 –OSTIA L4 (UKMO) -Aqua/Terra MODIS L2P (JPL) -GOES 11/12 L2P (OSDPD) -AMSRE and TMI L2P_GRIDDED (REMSS) -Actively assisting NCDC, JAXA, Bluelink with their GHRSST products. Level 4 read software in C and IDL created Supporting NASA Physical Oceanography RA Presented at the Medspiration/GlobCOLOUR meeting Dec 2006 Dealt with a number of operational anomalies including REMSS metadata “storm” Increased robustness with LTSRF data/metadata exchange - no byte of data dropped
6
Continued MODIS L2P 1 km global data streams –Aqua in June 2006, Terra in Sept. Only L2P with ocean color measurements Include mid IR SST in nighttime –6 Gbytes/ day but large number of daily granules (288/day) allow for efficient subsetting –Acquiring “refined” MODIS L2 datastream with 10 day lag.
7
Continued Ancillary filling for L2P – using FNMOC SST and ECMWF Exists in prototype form on Linux cluster –Two modes for filling Realtime (use forecast fields) 10 day lag (use analysis fields)
8
Filling for solar insolation ECMWF Solar insolation Same day AVHRR L2P filled with solar insolation data

PO.DAAC Architecture Supporting GHRSST 1 23 4 5 6 7 8 PO.DAAC is undergoing an extensive redesign in data management to promote more automation,technology enhancements and interoperability
10
GDAC Transition to PODAAC The goal at PO.DAAC is to have the Ingest, Inventory, Archive and Generate subsystems completed this 2007 year with GHRSST integrated and ready for testing at the beginning of 08. Features required for Support and GHRSST Interface will be added prior to March 08 with new PO.DAAC features continuing. –Currently GDAC is using POET and NERIEDs. –PO.DAAC is redesigning both the POET and NERIEDs (Near Real Time) interfaces to be fully integrated as clients to the Product Server in Support. –OpenDAP use will be expanded and extended on PO.DAAC as part of the Support subsystem. –Currently, the GDAC website exists and will be integrated with the PO.DAAC site. The GDAC website will require modification to query the PO.DAAC database within the Inventory subsystem. This will be done during this next FY under the original proposal funding. –User support will be provided by the Support subsystem (PropWeb ©, http://www.pcaonline.com), which is available on PO.DAAC. –Integrate metrics and reporting with PO.DAAC EMS reporting. Provide reports to RDACs, NASA and NOAA. Nettracker © http://www.unica.com/ EOSDIS Provided and managed metrics tool for trackiing input and output of products too all DAACs.http://www.unica.com/ 78

Data Use Cases and Applications –US regional users for climate, weather and ecosystem studies at federal or state agencies, non profit organizations, universities. Shorterm prediction and research center (SPORT) Pacific Disaster Center –Asia Pacific Natural Hazards Information Network NASA Aquarius Salinity Mission IOOS programs –Gulf of Maine Ocean Observing System (GOMOOS) –Southern California Coastal Ocean Observing System (SCCOOS) Ecosystem Management –California State University Humbolt Bay –NOAA Protected Species Management Southeast Phytoplankton Monitoring Network (SEPMN) ECCO2 comparisons Univ of Washington cruise support (Kuroshio)
16
Data Use Cases continued –US regional users for climate, weather and ecosystem studies at federal or state agencies, non profit organizations, universities coordinated by the GDAC. Shorterm prediction and research center (SPORT) SPORT supports infusion of NASA observations, data assimilation and modeling research into NWS forecast operations and decision making at the regional and local level. Using the OSTIA product for modeling and forecasting activities for the US Gulf and North Atlantic regions. SPORT is generating daily images available at: http://weather.msfc.nasa.gov/ sport/sstAnimation/ http://weather.msfc.nasa.gov/ sport/sstAnimation/
17
NOGAPS TC track Although there was no significant difference in the track forecast errors overall, there were areas where the use of the MISST SST analyses resulted in significantly improved NOGAPS TC track forecasts
18
ECCO2: linkages to the modeling community Capitalize on the results and expertise of ECCO2 and GHRSST-PP lead by Liming Li at JPL with the following goals: use GHRSST products to improve model estimates of air-sea interaction and circulation provide user feedback to GHRSST toward improving products develop increased understanding of processes affecting SST small scale variability and high frequency

Data Use Cases –The PDC has pledged their support to prepare and disseminate gridded GHRSST data via the APNHVA. –Atlas is published both as Asia Pacific basin-wide and Hawaiian Island region. –Support disaster community applications for preparedness, mitigation, response and recovery activities. –User include Hawaii State Civil Defense, FEMA, NOAA, UN agencies, Thailand’s National Disaster Warning Center and Vietnam’s Disaster Management Committee. –http://www.pdc.org Pacific Disaster Center
22
PO.DAAC Event Viewer Web interface to remote sensing products for “events” for scientific use Currently focused on hurricanes and typhoons –Providing a new generation high resolution winds from QuikSCAT –Uses OSTIA L4 and NCDC L4 as SST source In the future will be tuned for other “events”
23
JPL collaborations w/ Google and ESRI Near realtime earth remote sensing data from oceans, atmosphere and land in Google Earth environment for public consumption ESRI tools and services to support science and govt management GHRSST products are well situated to support these activities because of our information management infrastructure.
24
JPL Datacasting Model: an RSS-like feed for satellite data streams Client can subscribe to feed: “aware” on new data as soon as it is available Provider can package feed with metadata that consumer can filter on (e.g., location, cloud free pixels etc.) Datacasting is being prototyped on GHRSST L2P data
25
Future work PO.DAAC integration Datacasting L2P subsetting Historical MODIS L2P and other data streams
