| Zusammenfassung |
| Hyperspectral radiative transfer simulations are a versatile tool in remote
sensing but can pose a major computational burden. We describe a simple
method to construct hyperspectral simulation results by using only a small
spectral subsample of the simulated wavelength range, thus leading to major
speedups in such simulations. This is achieved by computing principal
components for a small number of representative hyperspectral spectra and
then deriving a reconstruction matrix for a specific spectral subset of
channels to compute the hyperspectral data. The method is applied and
discussed in detail using the example of top-of-atmosphere radiances in the
oxygen A band, leading to speedups in the range of one to two orders of
magnitude when compared to radiative transfer simulations at full spectral
resolution. |
