  1. OSSE Status and Future work FAB Observation Thrust Area

  2. Primary Objective • To establish a numerical test bed that would enable a hierarchy of experiments to: • determine the potential impact of proposed space-based, sub-orbital, and in situ observing systems on analyses and forecasts, • evaluate trade-offs in observing system design, and • assess proposed methodology for assimilating new observations in coordination with the Joint Center for Satellite Data Assimilation (JCSDA). • Sub-objectives • To define both the advantages and limitations of a hierarchy of OSSEs that includes rapid prototyping of instrument or data assimilation concepts, as well as the more rigorous “full” OSSEs. • (2) To generate an OSSE/OSE process that invites participation by the broad community of agency planners, research scientists and operational centers.

  4. Accomplishments • 3.5 year effort calibrating the NOAA joint OSSE for 5 major observation instruments; • First calibrated OSSE for UAS on hurricane track; • WISDOM OSSE; • Targeting observation with a ET new method and improvement of ET method efficiency (A journal paper submitted to JAS); • Coordination with AOML, NCEP and NSSL on NOAA OSSE testbed planning and proposals.

  5. Bob Atlas NOAA OSSE testbed slide: KeyPersonnel and their role in NOAA OSSE testbed Dr. R. Atlas, NOAA/AOML: Lead development of testbed, and along with a team of scientists, led by Dr. Lars Peter Riishojgaardat the JCSDA and Dr. TomislavaVukicevicat AOML: conduct and evaluate global and mesoscale OSSEs. Dr. Yuanfu Xie, NOAA/ESRL/GSD: Lead global OSSEs using the ESRL OSSE system and participate in regional OSSEs for UAS and HFIP. Drs. SharanMajumdar and David Nolan, UM/RSMAS: Generate mesoscale nature runs and participate in hurricane OSSEs. Dr. Ross Hoffman, AER: Chair of External Advisory Group. Dr. G.D. Emmitt, SWA: Simulation of Wind lidar and other observing systems.

  6. Future Works • Continuation of UAS OSSE for hurricane track forecasts to accumulate statistics; • Hyperspectral sounder OSSE; • GPS RO OSSE; • Regional OSSE for severe storms, e.g., hurricane intensity with AOML, …… • Development of a new more effective adaptive observation scheme for high resolution applications.
