Documentation Examples Download Web Interface Support Acknowledgments

Streamer is a radiative transfer model that can be used for computing either radiances (intensities) or irradiances (fluxes) for a wide variety of atmospheric and surface conditions. Its interface is very flexible and easy to use. Streamer's major features are:

There are, of course, some limitations. How does Streamer compare to other popular models? Some of the major similarities and differences are shown in this table.

Processing is controlled by a file that contains a set of options, a set of input data, and optionally some commands to control printing, variable reassignment, and looping. Output can be customized.

Streamer is written in standard Fortran 77 and will run on any platform with a Fortran compiler. Memory usage is small to moderate, and there are no special hardware requirements.

What's New

Version 3 includes DISORT version 2, the capability of specifying a surface bidirectional reflectance function or a built-in BRDF model, a variety of ice crystal "habits" (shapes), a facility to input cloud optical properties including a phase function, the option to compute cloud water content from optical and geometrical thicknesses, an interactive mode of execution with new commands, and much more!
