Improvements to and complementary systems for a differential absorption lidar system for field work are discussed. A dual-wavelength laser and a dual-wavelength detection system, which make DIAL with simultaneous lidar measurements at two wavelengths possible, are described. A multiwavelength measurement routine, which will improve accuracy and detection limits, is proposed. A dual-beam lidar system for measurements of plume velocity is also described.
