3 Atmospheric Modeling Applications Branch Strategic Vision
VISION: Lead developer of emerging technologies to build computationally feasible & accurate Nowcasting capabilities & weather decision support tools. MISSION: Research and develop the most accurate and timely battlefield mission execution weather data and products for the Warfighter. Weather Decision Support Tools Army-scale weather forecast & “Nowcast” models Support Intel Running Estimates and Artillery Meteorology Warfighter Value Assessment OBJECTIVES: Develop next generation mission execution forecast model (Nowcast). Web services & new/improved weather decision products at all echelons. Assess Nowcast & weather tool accuracy & value added to Warfighter.

4 Current Operations: Aerostat Operations Support
U.S. Forces – Afghanistan (USFOR-A) Joint Urgent Operational Needs Statement (JUONS) for Improved Weather Forecasting (CC-0432) Persistent Threat Detection System (PTDS) Length: 35m Persistent Ground Surveillance System (PGSS) Length: 22m Tailored Objective Analysis and Turbulence Parameterization for the 3DWF Diagnostic Wind Model Weather Running Estimate-Nowcast (WRE-N) Coupled to 3DWF My Weather Impacts Decision Aid (MyWIDA) Atmospheric Hazard Assessment and Rules of Thumb for PSS Sites in OEF Theater Local Met Sensors Feasibility Study and Demonstration Over 30 Persistent Surveillance Systems either lost/damaged since January 2011 where weather was a significant contributing factor.

7 Atmospheric Dynamics Branch
Vision: Provide highly detailed knowledge of Army relevant microscale environments, turbulence and propagation effects on systems Mission: Perform basic and applied research to measure, model, predict and understand the dynamics of the boundary layer atmosphere for its effects on Army systems and operations Research Areas: Atmospheric Turbulence and Effects Research Oblate <-- Non-isotropy --> Prolate MET in urban, mountain and forest terrain Local-Rapid Evaluation of Atmospheric Conditions (L-REAC) application Boundary Layer Dynamics Atmospheric Propagation Dynamics Microscale Meteorological Modeling Local-Rapid Evaluation of Atmospheric Conditions (L-REAC) Project Google Earth display

8 Runs in less than a minute for immediate decisions
3D Wind Field (3DWF) Model for winds in urban, mountainous and forested terrain 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 3DWF TKE Hazard Warning 3DWF is being implemented by the Air Force for daily operational support to the AF/ Army in March as part of the Aerostat JUONS effort. 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 2D ABLE flow

9 Bio-inspired Environmental Awareness
$4.5M ARL BED SBIR Program in bio-inspired environmental awareness for autonomous systems 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 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 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. Physical Sciences Inc. (Andover, MA) MK-2 InstantEye 20 cm, 200g, DoD Rapid Reaction Technology Office and Marine Corps funded deployment Future Nano Air Vehicles will use more responsive adaptive flapping wing controls
