Atmospheric Physics is the study of physical processes in the atmosphere; understanding the climate and the weather, and the physical reasons it is as it is and how it might change in the future. My own particular research background is in radiative transfer and I mean the transport of electromagnetic radiation through the atmosphere; the Sun’s radiation coming in, getting absorbed and scattered in the air, and the transfer of heat radiation emitted by the Earth’s surface. From a __________ physics perspective there’s an awful lot of things about the atmosphere that we don’t understand, and of course, it’s very classical physics in the that it’s looking at fluid dynamics and thermodynamics applied to the natural environment. What motivates us really is to try and explain what we see in the environment, what it and what might change it in the future, both in of local weather but also climate, by I mean larger areas and larger timescales. My background has led me to an interest in how solar radiation in the atmosphere, so at how changes in the Sun might affect the climate for the past year.

Atmospheric Physics is the study of physical processes in the atmosphere; understanding the
climate and the weather, and the physical reasons __________ it is as it is and how it might
change in the future.
My own particular research background is in radiative transfer and I mean the
transport of electromagnetic radiation through the atmosphere; the Sun’s
radiation coming in, getting absorbed and scattered in the air, and the transfer of heat radiation
emitted by the Earth’s surface.
From a physics perspective there’s an awful lot of things about the atmosphere
that we don’t understand, and of course, it’s very classical physics in the that it’s
looking at fluid dynamics and thermodynamics applied to the natural environment. What
motivates us really is to try and explain what we see in the environment, what it
and what might change it in the future, both in of local weather but also climate,
by I mean larger areas and larger timescales.
My background has led me to an interest in how solar radiation in the
atmosphere, so at how changes in the Sun might affect the climate for the past
year.
