Validation of the background simulation model MATISSE: comparing results with MODIS satellite images
2011
Generally available satellite images, e. g. from the MODIS sensor, provide data in spectral bands, which are suitable for
remote sensing applications and earth surface observations. However, for some applications different bands as well as
specific cloud formations for a certain region may be of interest, thus making the simulation of background data
essential. Therefore, the software MATISSE ("Advanced Modeling of the Earth for Environment and Scenes
Simulation") proved to be the appropriate tool. MATISSE is an infrared background scene generator developed by
ONERA for computing natural background spectral radiance images including atmosphere, sea, land and high and low
altitude clouds. In order to validate the model, comparisons with MODIS satellite data have been carried out using
images in available spectral bands. The investigations comprised selected surface structures like sea, desert, lowland
(dry) and highlands (humid). In general, the results on radiance images show a good correlation between MODIS image
and the MATISSE-simulation.
This paper focuses on comparing results between simulated MATISSE radiance images and the MODIS observations.
Based on this, possible sources of error and the limits of the model are discussed.
