Institute for Atmospheric Optics and Remote Sensing (IFAORS)


The longest operating division of TI since 1976, IFAORS has built an excellent international reputation in the field of atmospheric sciences, remote sensing and data management and analysis. In successful support of its several national and international clients, including the National Aeronautics and Space Administration (NASA), National Oceanographic and Atmospheric Agency (NOAA), Environmental Protection Agency (EPA), U.S. DOD (Army, Air Force and Navy), and the World Meteorological Organization (WMO)/ World Climate Research Programme (WCRP), IFAORS has developed exciting and innovative high-technology solutions to problems in areas as diverse as the space program, defense against chemical and biological agents, low observable smokes/obscurants & countermeasures, applications of remote sensing for management & production of rice, and for the fight against vector-borne diseases and illegal drugs.

IFAORS is a not-for-profit research institute for the science and technology of atmospheric optics, solar radiation, environmental and space remote sensing, and ground-truth measurements. Of special interest are applications of this research to the solutions of problems related to food and water resources, weather and climate, energy and natural resources, and environmental pollution and health.

Long-range direction and guidance of IFAORS is provided by a Technical Advisory Council (TAC), comprised largely of expert scientists from several universities and research laboratories.
