• Resumen

  • Spaceborne lidars are an established and proven technique used or to be used in many atmosphere research and applications for Earth and Planetary remote sensing. Four classes of lidar sensors are being addressed at the European Space Agency (ESA): wind Doppler, backscattering lidar, Altimeter and DIAL lidar. Two lidar instruments are presently under development within two satellite programs: the Doppler wind lidar ALADIN (on the ADM-AEOLUS satellite), the Backscattering lidar ATLID (on the EarthCARE satellite). In addition, various concepts of Differential Absorption lidar are being investigated/proposed in Earth Observation as follow-on missions to the ADM or EarthCARE: a total column DIAL for atmospheric CO2 measurements (proposed for the A-SCOPE mission), or a range-resolved DIAL for water vapour measurements (proposed for SPACE WAVES mission). On the planetary missions, ESA is engaged in the development of an Altimeter lidar for the space mission to Mercury (Bepi Colombo) for terrain profiling and for the ExoMars mission a Dust-particle and wind anemometer is being developed as part of the payload. This paper presents the instruments´ concept and related technology/instrument developments that are currently in progress at the European Space Agency, with emphasis on the Earth Observation applications for Meteorology and Climatology.
