1. 1. Deriving characteristics of thin cirrus clouds from observations with the IRF lidar

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Jennifer Edman; [2019]
   Nyckelord :cirrus; lidar; polar regions; optical thickness; clouds; ice clouds; BSR; backscatter coefficient;

   Sammanfattning : Cirrus clouds play an important role in radiative transfer, and thus have impact on the energy balance of the atmosphere and the climate of the Earth. Furthermore, they occur often and cover large areas globally at any time. Nevertheless, cirrus clouds are poorly studied, especially in the polar regions. LÄS MER

3. 2. Design of Algorithms to Extract Atmospheric Aerosol Extinction from Raman Lidar Data

   Uppsats för yrkesexamina på grundnivå, Institutionen för fysik, kemi och biologi

   Författare :Erik Thorin; [2006]
   Nyckelord :Lidar; Raman; Laser; Aerosol; Extinction coefficient; Backscatter coefficient; Atmosphere; Matlab;

   Sammanfattning : This thesis project describes how the retrieval of aerosol extinction and backscatter coefficients is computed from data obtained with a Raman lidar at FOI, Swedish Defense Research Agency. The theory is described, the implementation is done and problems discovered along the way are discussed. LÄS MER
