A remote sensing system includes a transmitter for generating multiple beams of light; a combiner for combining the multiple beams of light and directing the combined multiple beams toward a target of multiple gases; and a receiver for receiving the combined multiple beams of light from the target. The first and second transmitted beams of light include, respectively, first and second sets of multiple distinct wavelengths that are simultaneously transmitted toward the target. The receiver receives the multiple distinct wavelengths, and simultaneously detects an intensity of each received wavelength. The first set of multiple distinct wavelengths is selected based on absorption characteristics of a first species of gas, and the second set of multiple distinct wavelengths is selected based on absorption characteristics of a second species of gas. The transmitter includes first and second mode-locked based lasers for generating, respectively, the first and second sets of distinct multiple wavelengths. The receiver includes first and second pixel arrays for detecting, respectively, the first and second sets of distinct multiple wavelengths.
