Reflectivity model

WebRadar reflectivity values did not exceed -25 dBZ even with visibilities less than 100 m. The onset and evaporation of fog produce different radar reflectivity-visibility relationships. The evolution of the fog layer was modeled with a droplet activation model that used the aerosol size distribution observed at the 60-m altitude tower level as ... WebCalculate and plot the horizontal and vertical reflectivities from the GIT model. The radar operates at an L-band frequency of 1.5 GHz at grazing angles from 0.1 to 10 degrees. Assume sea state 3. seastate = 3; graz = 0.1:0.2:10; freq = 1.5e9; model = 'GIT'; Compute the horizontal and vertical polarized reflectivities.
