Airborne tracking sunphotometer
An airborne tracking sunphotometer, mounted on the outside top surface of an aircaft has been developed to provide unresricted viewing of the sun. This instrument will substantially increase the data that scientists can gather for atmospheric studies. The instrument has six wavelength channels and an automatic data gathering system. The instrument's optical features, tracking capability, mechanical features, and data gathering system are described.
