Abstract

The stationary lidar system MARTHA at TROPOS has undergone a major upgrade. With a new diode-pumped laser, the average laser power has more than doubled. In combination with the large far-range telescope, this will allow us to profile the atmosphere from the ground up to the stratosphere. A new spectrometer with an extra telescope enables spectrally resolved measurements of laser-induced aerosol fluorescence, which shall allow unambiguous aerosol typing and the characterization of biogenic aerosol particles. The upgrade and the features of the new system are described and range-corrected signals from a first test measurement are presented.
