Abstract

Despite the outstanding progress made during the last decade in observational methods such as passive emission spectrometry and active Lidar applications, infrared remote sensors using the sun as source of radiation remain among the most powerful tools for atmospheric investigations. The quality and quantity of such solar observations have reflected the progress made in detector sensitivities, in new instrumental techniques and modes of operation, as well as the power of analytical algorithms based on modern computers. Infrared spectrometers have been adapted and proven suitable for measurements from the ground, aircraft and balloons, even from orbiting platforms with extensive vertical and near-global coverages.
