| What's R-Pstar3 |
| 'Pstar3' is a general package for simulating polarized radiation fields in the coupled atmosphere-land/ocean system. 'R-pstar3' is a Rstar-like Pstar package to merge and integrate Rstar and Pstar.
The simulation is based on Stokes vector calculations based on the Discrete-ordinate/Matrix-operator method, which is applied to plane parallel atmosphere divided into several homogeneous layers with underlying ground or ocean surface. Pstar3 is also capable of handling radiative transfer coupled with plane parallel ocean (Ota et al., 2010). The original Pstar3 had been originally developed for Greenhouse Gases Observing Satellite (GOSAT) project of National Institute for Environmental Studies (NIES), Japan. The R-Pstar3 has been supported by JAXA/EORC, Japan. The package of R-Pstar3 is distributed via the Open CLASTR project (http://157.82.240.167./~clastr/). |
