Atmospheric science is the study of the dynamics and chemistry of the layers of gas that surround the Earth, other planets and moons. This encompasses the interactions between various parts of the ...

Abstract: Attenuation factors for the contrast of objects lying on the earth's surface and observed through five different atmospheric models are calculated as a function of the wavelength ...

An atmospheric river weather system drenched parts of southern British Columbia over the weekend, dumping more than 100 millimetres of rain in some locations and setting off a landslide.
