Abstract

We describe a hyper-spectral measurement technique for sprite observations which takes data at 25,000 samples per second in 32 individual color bands. The high speed hyper-spectral design is based around a 32 channel multi anode photometer (MAP) viewing a dispersing grating which is holographically inscribed on a spherical focusing mirror. Design and operating characteristics of the device are presented. The high speed hyper-spectral instrument will be used to observe spectra from transient luminous events called sprites seen above meso-scale thunderstorms. Sprites are seen to occur at altitudes of 40-90 km, and last a few to tens of milliseconds in duration. High speed spectral measurements may give some indication of the energetic processes underlying sprite formation. We are particularly interested in the overall energy budget associated with sprites in large meso-scale thunderstorm complexes.
