aerosol-radiation interactions 2

Question 1

what are 3 methods satellites use to remote sense of clouds

Answer 1

-solar wavelengths
-terrestrial wavelengths
-microwaves

Question 2

define cloud droplet effective radius

Answer 2

the area-weighted mean radius of the cloud droplet distribution

Question 3

describe the principals of aerosol remote sensing at solar wavelengths

Answer 3

-examines the additional reflected radiance relative to an aerosol-free atmosphere
-cloud screening applied
-modelled versus measured reflectance at multiple solar wavelengths
-forward-model used to develop a look-up table and the reflectance difference between the modelled and measured irradiances minimised

Question 4

what is an additional method that cloud remote sensing can use?

Answer 4

-use two view angles to detect height of aerosol plume
