    Satellite data from the Advanced Very High Resolution Radiometer AVHRR have been widely employed for fire monitoring around the world by virtue of the thermal emission in the middle-infrared mid-IR channel at 3.7 μm. This channel, however, receives both thermal emission...

    Quantification of the functional relation between remotely-sensed data and commensurable ground based observations is a basic prerequisite in many remote sensing studies. To this end, linear regression analysis is generally employed. Given two matrices of paired noise-i...

    The potential value of combining broadband and multispectral thermal infrared (TIR) data with multispectral and hyperspectral visible, near-infrared (VNIR) and shortwave infrared (SWIR) data was investigated within the context of urban land-cover classification. Using a...

    Given widespread Amazonian deforestation, numerous studies have focused on how the regional hydrological cycle – in terms of precipitation (<i>P</i>) recycling from evapotranspiration (ET) – is impacted by deforestation. Nevertheless, climate macroscale and mesoscale mo...

    The multi-spectral reflectances measured from the satellite lead to soil surface information through models. Since these models are defined and validated at local scale, where the soil surface is considered to be homogeneous, the use of the models with satellite multi-s...

    The technique of rank ordering of spectral energy density samples was applied to high frequency (HF) ocean backscatter radar spectra to examine the properties of signal and noise in the record. HF ocean backscatter spectra have characteristic Bragg scatter lines and ban...
