Aeris LLC

Aeris LLC, doing business as Aeris, is a small business subchapter S corporation based in Louisville, Colorado, that delivers atmospheric science modeling, advanced data assimilation, chemical and biological defense simulation, and research-and-development services as a prime contractor (57% of recent awards) and subcontractor to larger defense and federal technology primes. The vendor competes under Total Small Business set-asides across much of its prime footprint and holds no SBA 8(a), HUBZone, or other preferential designation; it operates full-and-open and small business set-aside vehicles across defense and civilian agencies.

Aeris's capability portfolio centers on specialized atmospheric transport and dispersion modeling, weather-based unmanned aircraft systems traffic management optimization, meteorological data assimilation, urban environment modeling, and advanced software development for defense applications. Representative prime work includes an $11.6 million cost-plus-fixed-fee contract with the Defense Threat Reduction Agency (awarded September 2025, completing September 2030) to develop a digital twin system for chemical and biological sensors; a $5.6 million DTRA contract (February 2025, completing February 2029) for next-generation multi-scale chemical and biological hazard transport and dispersion modeling; and a $1.3 million SBIR Phase II award from DTRA (September 2024, completing September 2026) for AI-based 3D building model generation supporting chemical, biological, radiological, and nuclear hazard modeling. Aeris also carries active work under two Air Force Space Command indefinite delivery contracts valued at $4.98 million and $4.9 million for meteorological modeling, advanced data assimilation, mesoscale modeling, and transport and dispersion analysis supporting the Air Force Technical Applications Center's HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory) and ARGUS (Rapid-GPU Urban Modeling System) platforms.

The Defense Threat Reduction Agency and Air Force Space Command dominate Aeris's customer base by potential value, accounting for $29.6 million and $19.9 million respectively across 17 and 20 awards (94% coverage of recent awards). The Federal Aviation Administration, through subcontract work with MITRE on microscale weather modeling, represents substantial volume by award count (19 awards) but carries sub-award status. NASA and the Office of Naval Research round out the customer set, with a combined $1.6 million across five awards. Activity accelerated sharply in 2024 (33 awards) before moderating in 2025 (7 awards); three awards carrying $4.9 million in combined potential value reach ultimate completion inside the next twenty-four months and face recompete risk.

Aeris operates as a subcontractor on multiple platforms: MITRE accounts for the largest sub-engagement, with recurring orders for microscale weather modeling and large-eddy simulation (LES) model preparation, initialization, and execution work for urban weather and UAS traffic management applications across multiple cities. Applied Research Associates, Leidos, and Environmental Management & Planning Solutions round out the named prime relationships, spanning DTRA technical reachback, FEMA-led Interagency Modeling and Atmospheric Assessment Center (IMAAC) support, Environmental Data Enterprise services, and air quality modeling and greenhouse-gas inventory consulting. The vendor acts primarily as a prime on Defense Threat Reduction Agency and Air Force Space Command work and as a specialized atmospheric modeling subcontractor to systems integrators and engineering firms on civilian and joint-interest programs. Aeris also holds a Forest Service grant recipient status for a no-cost-extension project on wildland fire smoke dispersion modeling (awarded September 2024, completing September 2026).

The Service Contract Inventory dataset shows minimal invoiced federal services revenue across SCI-reportable contracts (zero reported across FY2022–FY2025 for prime records), with estimated FTE trajectory ranging from 0.0 in FY2022 to 0.7 in FY2025 — a partial and conservative floor reflecting only contracts above the $150,000 reporting threshold and excluding the majority of Aeris's research, development, and product-focused work. The top NAICS categories across the award portfolio span All Other Professional, Scientific, and Technical Services (25 awards), Engineering Services (19 awards), and Research and Development in the Physical, Engineering, and Life Sciences (13 awards), reflecting the vendor's concentration in specialized modeling and R&D delivery rather than labor-hour-intensive services.

Aeris, LLC is focused on developing science and engineering solutions for challenging aerospace and defense problems. We provide forensic meteorology, atmospheric modeling, software design/development and weather & climate analysis services.
