ELDEnvironmental Laser Division
Data analysis packages and simulation models for space-based and airborne Doppler lidar wind measuring systems, backed by field campaigns and Observation System Simulation Experiments.
Learn moreApplied meteorology since 1974
Science that works in the field, in the lab and in orbit.
Simpson Weather Associates provides meteorological consulting and research, airborne and space-based Doppler wind lidar applications, air quality modeling and monitoring, fugitive dust control and specialized field measurements.
Who we are
Two divisions, one scientific foundation
Since 1974, SWA has specialized in weather-related environmental problems. Our scientists and engineers in Charlottesville, Virginia work on efforts ranging from industrial fugitive dust mitigation and monitoring to airborne wind lidar measurements and model input.
