Within the Pollino National Park environmental monitoring promoted by the Basilicata Region authorities (southern Italy), hyperspectral airborne data surveys were deployed to collect spectra images with higher spectral/spatial resolution. In order to define a standard atmospheric procedure to be applied to MIVIS data set, different radiative transfers code has been tested. Unfortunately generic correction procedures, like ATREM, widely applied to airborne hyperspectral data sets, could not be used for MIVIS data set because of the absence of the specific water absorption bands (0.94 and 1.14micrometers ) in its spectral region coverage. In this paper a technique to recover the right slope of the water absorption bands centered at 0.82micrometers , not measured by the MIVIS spectral resolution, is presented. The synthetic 0.84micrometers channel is spectrally recovered in place, by using the spectral behavior of each pixel. Channel simulations have been conducted on AVIRIS data sets resampled on the MIVIS NIR spectral channel curves and compared with the AVIRIS ones recorded at 0.84 micrometers . Data simulation has proved the efficiency of the method and the spectral coherence of the synthetic bands centred at 0.84(mu) +m. As a consequence the atmospheric correction code ATREM, with the help of appropriate contrivance to rescale the water vapour atmospheric amount, could be applied to the MIVIS data set by selecting, in the ATREM input file, only the water absorption band centred at 0.82micrometers .
