Atmospheric and Environmental Research

What Atmospheric and Environmental Research does

Atmospheric and Environmental Research (AER) is a Lexington, Massachusetts-based environmental and atmospheric science research firm founded in 1977, employing 51–100 people. It provides environmental consulting and research services centered on atmospheric data analysis, weather prediction, and climate research, serving federal government agencies (its primary segment), defense and military clients, and commercial entities. Its core capability is physics-based environmental modeling and analysis applied to mission-critical operations, though the input does not disclose specific proprietary models, product names, or platforms developed by AER itself.

Prior to December 2024, AER operated as a business unit of Verisk (NASDAQ: VRSK), a publicly traded analytics company. On 2024-12-17, Verisk sold AER to JANUS Research Group, an Evans, Georgia-based private company specializing in AI-powered mission solutions for defense and federal clients, with D.A. Davidson serving as the exclusive financial advisor to Verisk. The transaction rationale explicitly cited leveraging JANUS' data science and AI/ML capabilities to enhance service delivery to AER's federal, defense, and commercial clients. JANUS operates solution lines spanning AI & Agentic Solutions, Software & Digital Solutions, Systems Engineering & Network Integration, Research to Operations, and Training/Simulation, and maintains proprietary platforms such as RAPTOR (a synthetic EO/IR/SAR signature generator used to train AI/ML target detection models), positioning the combined entity to integrate AER's atmospheric research into AI-enabled environmental intelligence offerings.

AER's business model is not publicly disclosed in terms of pricing, contract structures, or revenue mechanics. The segmentation is described as horizontal, with three named vertical segments (Federal Government, Defense Clients, Commercial Clients) and no published revenue per segment. AER has no disclosed subsidiaries, no disclosed product launches, no disclosed management team, and no disclosed patents, certifications, or partnerships beyond the D.A. Davidson advisory relationship on the JANUS transaction. Following the December 2024 acquisition, AER continues to operate as a unit of JANUS Research Group.

Broad incumbents

• Peraton: Federal contractor with significant atmospheric, environmental, and Earth science mission support for NOAA, NASA, and DoD. Competes with AER on environmental and atmospheric research programs at a larger integrator scale.
• AECOM: Global environmental and engineering consulting firm with a sizable federal and commercial atmospheric/air quality practice. Comparable to AER on environmental consulting and air quality work, though AECOM's footprint is far broader and skewed to infrastructure rather than defense.
• SAIC (Science Applications International Corporation): Large federal systems integrator and defense contractor with a significant atmospheric, environmental, and climate science portfolio serving NOAA, DoD, and NASA. Comparable to AER as a competitor for the same federal atmospheric and environmental research contracts but at much greater scale and with broader mission breadth.
• Booz Allen Hamilton: Premier federal/defense consulting and engineering firm with growing climate, environmental intelligence, and Earth observation advisory practices serving DoD and civil agencies. A competitor for AER's federal and defense environmental intelligence engagements.
• Leidos: Major federal contractor with deep atmospheric, oceanographic, and environmental science capabilities supporting NOAA, DoD, and civil agencies. Directly comparable to AER on atmospheric and environmental research program capture, with broader systems integration scope.
• Maxar Technologies: Space-based Earth intelligence company providing weather, environmental, and atmospheric data products derived from its satellite constellation. Comparable to AER in atmospheric and environmental data delivery to defense and intelligence customers, though Maxar is a satellite operator rather than a research services firm.
• Ball Aerospace (BALL): Develops and operates atmospheric and environmental remote sensing instruments and missions (e.g., for NOAA and NASA). Comparable to AER on atmospheric science and space-based environmental observation, though Ball is primarily a hardware/instrument prime rather than a pure research services firm.

Direct peers

• Riverside Technology, Inc. Specialized atmospheric and environmental science services firm supporting NOAA, DoD, and FAA. A close comparable to AER in scale, mission, and customer set — both deliver environmental intelligence and atmospheric research to federal agencies.
• I.M. Systems Group (IMSG): Mid-size scientific and technical services firm providing atmospheric, oceanic, and environmental research support primarily to NOAA and DoD. Closely comparable to AER in size, customer focus, and atmospheric/environmental research delivery model.
• ERT (now part of ECS Federal): Mid-size federal scientific services firm providing atmospheric, environmental, and climate science support to NOAA and other agencies. Closely comparable to AER in scale, mission focus, and federal customer concentration.
