Instantaneous Clear Sky Radiative Forcings of Halogenated Gases

W. A. van Wijngaarden, W. Happer

The clear sky instantaneous radiative forcings of the 14 halogenated gases previously shown to have the largest contribution to global warming, were found. The calculation used the…

Atmosphere and Greenhouse Gas Primer

W. A. van Wijngaarden, W. Happer

We discuss how greenhouse gases affect radiation transfer in Earth's atmosphere. We explain how greenhouse gases like water vapor or carbon dioxide, differ from non-greenhouse gase…

2n-Stream Thermal Emissions from Clouds

W. A. van Wijngaarden, W. Happer

We analyze thermal emission of radiation in homogeneous clouds. The clouds have negligible horizontal variation, but the temperature can vary vertically. The radiation at optical d…

Nitrous Oxide and Climate

C. A. de Lange, J. D. Ferguson, W. Happer +1

Higher concentrations of atmospheric nitrous oxide (N2O) are expected to slightly warm Earth's surface because of increases in radiative forcing. Radiative forcing is the differenc…

2n-Stream Conservative Scattering

W. A. van Wijngaarden, W. Happer

We show how to use matrix methods of quantum mechanics to efficiently and accurately calculate axially symmetric radiation transfer in clouds, with conservative scattering of arbit…

2n-Stream Radiative Transfer

W. A. van Wijngaarden, W. Happer

We use 2n streams, where n is an integer, of axially symmetric radiation to solve the equation of transfer for a layered medium. This is a generalization of Schuster's classic 2 st…
