OSSE Status and Future work

FAB Observation Thrust Area


Osse status and future work

  • 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.

Accomplishments

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.

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.


Future works

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.
