Auroral/Ionospheric Remote Sensor

NSSDCA ID: 1986-088A-02

Mission Name: Polar BEAR
Principal Investigators:Dr. Robert E. Huffman
Principal Investigators:Dr. Ching I. Meng


The Auroral/Ionospheric Remote Sensor (AIRS) is intended to give simultaneous synoptic information through optical remote sensing of the ionosphere. The instrument consists primarily of a two-channel vacuum-ultraviolet (VUV) imaging spectrometer which can operate in any of three modes. The full-imaging mode provides auroral/ionospheric images in any two of six selectable wavelengths in the range 1100 A to 1900 A, each with a bandwidth of 30 A. Cross-track line scans with 336 pixels per line can yield nadir resolution of 5 by 20 km at auroral altitude. The other two modes are fixed nadir-viewing ones. One of these modes is a spectrophotometer mode in which a 30-A filter can be swept from 1100 A to 1900 A. The other mode is a simple fixed-wavelength photometer mode. In addition to the VUV imaging spectrometer, AIRS contains two nadir-viewing visual-wavelength photometers. One operates at 3914 A and the other operates at 6300 A.
