Question

Use the data provided below to plot the one-way attenuation due to warm (water droplet) clouds.
Plot the attenuation (y-axis) versus wavelength (x-axis) for each cloud temperature.

Use the data provided below to plot the one-way attenuation due to warm (water droplet) clouds. Plot the attenuation (y-axis) versus wavelength (x-axis) for each cloud temperature. 1-way Attenuation (db/km/g/m2) at 4 Different wavelengths (from Gunn & East-1954 Water cloud a 20C 0.9 cm 0.647 0.99 1.24 cm 0.311 0.523 1.80 cm 0.128 0.267 3.2 cm 0.0483 0.0858 Water cloud a 0C Questions: 1.1 Summarize how attenuation changes due to cloud temperature and wavelength of the radar 1.2 Compare the attenuation you would expect at the radar antenna for a signal passing through a 5 km thick cloud at 0C and +20C. Assume your radar has a density is 1 g/m 3.2 cm and the cloud

Explanation / Answer

One way atmospheric attenuation plotted as a function of wavelength for different water vapor content values. The s band and ka band are indicated by dots . The dashed curve indicates liquid water attenuation for a rain rate.
