New features in SCIATRAN 2.0
|
|
|
Spherical mode added (can be used for solar zenith angles up to 98 deg). User can switch between the pseudo-spherical and the spherical mode.
|
|
|
All viewing geometries supported (nadir, off-nadir, zenith-sky, off-axis, limb).
|
|
|
Any observer position supported (TOA, BOA, any point within and above the atmosphere).
|
|
|
Fild of view integration in spherical mode (at the moment for SCIAMACHY instrument in limb mode only).
|
|
|
Extended spectral region: 175 - 2400 nm.
|
|
|
Spectral data base for line absorbers (including c-k distribution scheme) is updated to HITRAN 2000.
|
|
|
Photochemically active species can be considered in spherical mode.
|
|
|
New radiative transfer core in pseudo-spherical mode (based on discrete-ordinates method).
|
|
|
Extremely fast quasi-asymptotical approach to calculate reflected radiance in a cloudy atmosphere within line-absorber (O2, H2O, etc.) spectral bands.
|
|
|
Linearization (weighting functions) with respect to trace gas concentrations in spherical mode and with respect to all atmospheric parameters (trace gas concentrations, pressure, temperature, Rayleigh scattering, aerosol and cloud parameters) in pseudo-spherical mode.
|
|
|
Incorporated retrieval block based on either Optimal Estimation or Information Operator approach (alternatively).
|
|
|
Parallel computation on SMP systems (Open MP standard).
