Abstract:
1. A method of making and using measurements for gas filter correlation radiometry, comprising the steps of: providing a Gas Filter Correlation Radiometer (GFCR) instrument capable of making a measurement viewing through a gas cell; moving the GFCR instrument in a region of space surrounding a heavenly body along a velocity vector; viewing an atmosphere of the heavenly body with the GFCR instrument along a first view direction wherein the atmosphere and the GFCR instrument experience a relative velocity of approximately zero along said first view direction, wherein the GFCR instrument generates a first signal associated with said first view direction; viewing the atmosphere with the GFCR instrument along at least one second view direction that is angularly separated from said first view direction wherein atmospheric spectra associated with said second view direction appears Doppler shifted with respect to atmospheric spectra associated with said first view direction, wherein the GFCR instrument generates at least one second signal associated with and corresponding to said at least one second view direction; and performing a gas filter correlation radiometry application using said first signal and said at least one second signal.
