dynamics of the boundary layer atmosphere
for its effects on Army systems and operations
Research Areas:
• Boundary Layer Dynamics
Oblate <-- Non-isotropy --> Prolate
MET in urban, mountain
and forest terrain
Local-Rapid Evaluation of Atmospheric

3D Wind Field (3DWF) Model for winds in
urban, mountainous and forested terrain
3DWF is being implemented by the
Air Force for daily operational
support to the AF/ Army in March
2012 as part of the Aerostat JUONS
effort.
Air Force highest resolution operational 1.67 km WRF forecast winds feed
higher resolution 50m 3DWF for winds at 20 m AGL in mountainous terrain
Runs in less than a minute for
immediate decisions
Also produces Turbulent Kinetic
Energy (TKE) 3D profiles to warn of
shear conditions.
The follow on Atmospheric Boundary
Layer Environment (ABLE) Model will
be a full physics forecast model for
urban and mountainous terrain

Bio-inspired Environmental
Awareness
$4.5M ARL BED SBIR Program in bio-inspired
environmental awareness for autonomous systems
Wind turbulence both inside and outside buildings
significantly impacts Micro and Nano Air Vehicle
(MAV/NAV) autonomous hover and navigation
through windows and small openings.
Based on insect and bird awareness sensors and
autonomic processing a system is developed that
has total awareness of its own mechanical state,
can cope with minor damage and avoid collisions
autonomously, freeing up the operator for
attention to mission.
This program currently has active:
• Three Phase I SBIR
• Two Phase II SBIR
• One Phase III deployment SBIR
• Proposals for follow-on FY13 Phase I SBIR
Key Deliverables in FY12:
• 20 MK-2 InstantEye developmental test
systems for early deployment evaluation
• 100 MK-3 systems for deployment using
adaptive gust-rejection techniques
developed under this SBIR program
