The Department of Energy's Atmospheric Radiation Measurement (ARM) Program uses state-of-the-art active and passive remote sensing instrumentation to study the fundamental physics related to interactions between clouds and radiative feedback processes in the atmosphere. With instrumentation located in three different climate regions around the world, plus a mobile facility for accessing different climates, datasets provided by the ARM Program are used to improve the treatment of clouds and radiation processes in climate models. The DOE is one of the biggest funders of science research in the US The United States Department of Energy National Laboratories are a system of research facilities and laboratories funded and controlled by the United States Department of Energy (DOE) for the purpose of advancing science and helping promote... A black hole concept drawing by NASA. Physics (from the Greek, φυσικός (physikos), natural, and φύσις (physis), nature) is the science of the natural world dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. ... Cumulus of fair weather A cloud is a visible mass of condensed droplets or ice crystals suspended in the atmosphere above the surface of the Earth or another planetary body. ... Layers of Atmosphere (NOAA) Earths atmosphere is a layer of gases surrounding the planet Earth and retained by the Earths gravity. ... Climate models use quantitative methods to simulate the interactions of the atmosphere, oceans, land surface, and ice. ...
