Abstract : The Aerospace long-path infrared absorption cell is described. This facility is a multiple-pass modified White cell which can be operated at any temperature between 170 K and room temperature with path lengths from 60 m up to 4 km. The cell itself is an 11-m long double-walled aluminum dewar. The spectral coverage extends from visible to 50 micrometers using as a source either a high temperature blackbody or a tunable diode laser. An internal 20 kV flash photolysis system will permit detection and kinetic studies of transient species. This combination of characteristics makes the system ideally suited to study a wide variety of upper and lower atmospheric phenomena under realistic conditions as well as other phenomena requiring low concentrations or high sensitivity.
