OASES

• Is a re-engineered version of TAOS
• Reuses many components of TAOS
• Complements the INE ARP w/ runtime services
• Has these primary subsystems
• Environmental Data Ingestor (EDI)
• Environmental Data Transformer (EDT)
• Environmental Tailoring System (ETS, formerly
  JETS)
• Environmental Data Visualizer (EDV)
• Environmental Data Server (EDS)
• Is a composable system

Current OASES Development and Integration
Activities

• Environment Federation
• DTRA MetServer Project
• Fleet Battle Experiments

12
Environment Federation
GFY01 OASES Development Goals d

• Precipitation editing algorithm for ETS
• Time Federate
• Support for Pause, Resume, Save and Restore
• Time Editor
• Productization of OASES Subsystems
• Formal software releases
• User Guides
• Expanded capability demonstration at Camp
  Pendleton
• Cloud, fog and haze effects on target acquisition
  (optical band)
• Precipitation effects on soil strength and
  vehicle mobility
• Chem/Bio effects as a function of weather
• Weather effects on aircraft carrier operations
• Shallow water acoustics for mine/counter-mine
  operations

13
DTRA MetServer

• Collaborative effort with ITT Industries
• Goal Enfederate legacy DTRA models and tools
• Nuclear, Chemical, Biological, Radiological
  (NCBR) Server
• HPAC/SciPuff and VLSTrack transport and diffusion
  models
• Weapons Analysis Lethality Tool Set (WALTS)
• Goal Integrate enfederated TD models with
  OASES
• Use Base Object Model concepts to develop FOM
  from subsets of RPR and EnviroFed FOMs (see
  01S-SIW-041)
• Goal Support use of multiple weather models
• MM5
• COAMPS
• RAMS
• OMEGA

OMEGA Operational Multi-Scale Environment Model
with Grid Adaptivity

• Model embeds the Atmospheric Dispersion Model
• Grid is unstructured both horizontally and
  vertically
• Vertices lie on earth-centered radials
• Grid can adapt in a variety of ways

Grid adapted to (static) topography

• Grid adapted to land-water boundary

16
OMEGA Operational Multi-Scale Environment Model
with Grid Adaptivity

• Grid adapted to weather at model initialization
• Grid recomputed at each time-step based on
  weather field gradients

Fleet Battle Experiments

• For background, see Improving the Water Column
  Representation, Maassel et al., 00F-SIW-060
• Mine/counter-mine operations in littoral region
• Water column model based on HydroQuals Estuarian
  Coastal Ocean Model (ECOM)
• Currently using TAOS V1.2
• Live Mode required
• ECOM data based on curvilinear grid published via
  Gridded Data PDUs
• EnviroFed III Goals
• Assist FBE in transitioning from TAOS to OASES
• Support Live Mode in OASES
• Extend EnviroFed FOM to explicitly include
  curvilinear coordinates

Summary

• DMSO is funding the development of a suite of
  composable applications for the simulation of
  ocean, atmosphere and space environments
• Its called OASES
• It is the run-time component of the Integrated
  Natural Environment programs Authoritative
  Reference Process
• Formal release scheduled for December 2001
• OASES is currently being integrated with
• JointSAF V5 (Environment Federation)
• OMEGA, NCBR Server, HPAC/SciPuff (DTRA MetServer)
• ECOM, PC-SWAT (FBE Federation)
• OASES recently selected by OneSAF program to be
  the provider of run-time ocean/atmosphere services
