- Steamer does not do any plotting. It can, however, output results in a
way that's easy to import into plotting programs.
Unless the cloud phase function is input by the user, it is approximated
using the asymmetry parameter and either the single or double Henyey-Greenstein
function. This is fine for fluxes but can result in significant errors when
radiances are being computed.
No atmospheric refraction or spherical geometry is included so that results
for solar zenith angles greater than about 70 degrees are subject to error.
The only gases considered are water vapor, oxygen, carbon dioxide, and
The flux/radiance that Streamer computes for the scene is the sum
of the fluxes/radiances computed for each cloud part (individual clouds
and overlap) weighted by their area fraction.
Shortwave calculations are not done when the solar zenith angle is 90 degrees
While different surface types can occur within a scene, they do not occupy
different portions of the scene; i.e., their reflectance signatures are
used to create a weighted average albedo for the entire scene.
