Particulate matter in the atmosphere impedes visibility,  contributes to global climate change and adversely affects human health. Aerodyne produces scientific instruments that measure various aspects of atmospheric aerosols.

Trace gases in the atmosphere are primary causes of photochemical smog, global climate change, ozone depletion and acid rain. To quantify, understand and control these problems, highly sensitive trace gas monitors are need. Aerodyne produces several instruments to measure trace gases whether on the ground or in the air.

Global climate change is driven by the accumulation of greenhouse gases (primarily CO₂, CH₄ and N₂O) in the atmosphere. To understand the rate of accumulation and to predict and measure the effectiveness of various control proposals, measurements of the fluxes of these gases to and from the atmosphere are required. Our fast response, high sensitivity trace gas instruments enable this capability.

The sources and sinks of various atmospheric constituents are important to quantify but difficult to measure. One approach to addressing this challenge is based on the measurement of the isotopic composition of atmospheric species. Because different sources tend to have distinct isotopic signatures, the measurement of concentrations or fluxes with isotopic resolution can highly constrain the potential sources and sinks. Aerodyne produces several instruments with isotopic measurement capability.

Many problems in science and engineering reduce to finding an efficiently constructed map of the relationship between sets of high dimensional system inputs and outputs. Our software program, ExploreHD, enables user-friendly analysis of large, high-dimensional datasets to extract critical and potentially complex, nonlinear information. Such information is useful for pattern recognition, model reduction, and parameter importance rankings.

Aerodyne hosts a web-based Comparative Emissions Database (CEDB) with detailed emissions data and online tools for comparing the potential environmental impact (especially for climate change) of moving passengers and freight via various transportation modes.

There is a rich spectral content in the reflection, scattering, and absorption of light in the UV, Visible, and Infrared by solid surfaces, particulates, gases, and liquids. Aerodyne develops and applies validated physics-based software to model spectral radiation transfer and imaging processes.
