  3. NOAA Sea Level Rise LSA website updated to include Jason-2 data and new calibrations. • Global mean & regional time series, global trend map, tide gauge calibrations Website provides the most accurate estimates of sea level rise currently available (Leuliette, E. W., R. Scharroo, 2010: Integrating Jason-2 into a Multiple-Altimeter Climate Data Record, Marine Geodesy, 33, 504-517) http://ibis.grdl.noaa.gov/SAT/SeaLevelRise/

  4. Recent Sea Level Rise Budget New analysis for January 2005 to March 2011 uses corrected Jason-1 and Jason-2 observations of total sea level, improved upper ocean steric sea level from Argo array, and ocean mass variations inferred from GRACE gravity mission. We show that the sea level rise budget can be closed, providing verification that the Jason altimeters, Argo array, and GRACE mission are providing consistent data. http://ibis.grdl.noaa.gov/SAT/SeaLevelRise/documents/NOAA_NESDIS_Sea_Level_Rise_Budget_Report_2011.pdf

  6. NESDIS Milestone for FY11-Q4: Publish annual qualityassessment report on NOAA Jason-2 data products M Jason-2 completed its third year of operations in July, 2011. The 2010-2011 Annual Data Quality Report for Jason-2 Near Real-Time products was submitted 27-Aug-2011. Plots of five primary measurements are analyzed cycle by cycle (left) and illustrate a very high level of quality overall. Anomalies which impact data quality include satellite maneuvers, calibrations and software uploads, instrument malfunctions, and ground station outages. Over the year, 94.49% of the data were available within 3 hours and 98.65% within 5 hours, exceeding NOAA’s requirements of 90% & 95%, respectively. The over-ocean data return for 2010-2011 was 99.84%. Significance: NOAA's role in Jason-2 includes data production and quality monitoring for near real-time data generated by both NOAA/ESPC & EUMETSAT. Annual reports provide a summary of anomalies, data outages, and overall data quality cycle by cycle for each year. Jason–2 continues the 15 year global sea level climate data record begun by Topex & Jason–1. ftp://ibis.grdl.noaa.gov/pub/johnl/ostm/j2_2010-2011_nrt_quality.pdf (Courtesy of J.

  11. Jason-2 Operations – Recent Updates • NOAA Continuity of Operations Test • EUM successfully backed up NOAA OGDR processing • NODC/CLASS & CNES/SIPAD monthly archive reconciles • Third “test/dev” string deployed at ESPC • Telemetry frame>packet processing moved from SOCC/J2TCCS to ESPC/FileManager • Command/Control post-processing now automated, with manual pass processing for proficiency

  12. Jason-2 Operations – Lessons Learned • Current NOAA Jason ground system is overly complicated • Still room for improvement in inter-agency communications (maneuvers, calibration file updates…) • Updates associated with ECMWF model grids, in particular, have resulted in numerous processing anomalies • Weekly OCGs and monthly CCB meetings have proven highly beneficial to maintain operational coordination • NRT end users state that Jason-2 is the most reliable, low-latency altimetric dataset ever
