Temperature measurements using Rayleigh Lidar Required pure - PowerPoint PPT Presentation

Temperature measurements using Rayleigh Lidar • Required pure molecular scattering • Density and pressure are relative measurements • Temperature is absolute r ( z ) = f ( N ( z ) dP ( z ) = - g ( z ) r ( z ) dz T ( z ) = MP ( z ) R r ( z ) top z å å g r ( z ') dz ' N ( z ') dz ' T ( z ) = M = Mg ( z ) z 0 r ( z ) R R N ( z )
