                         calibration campaign performed in the Atacama Desert, Chile, 
                         between the 18 and 22 August 2014, called the Atacama Field 
                         Campaign (ATAFIC 2014). In situ measurements were performed in 
                         order to spectrally characterize the surface reflectance spectra 
                         between 0.3 and 2.5 mu m, radiometric temperature (8.0-14.0 mu m) 
                         and atmospheric measurements. A soil sample was collected and 
                         analyzed using Fourier Transform Infrared Spectroscopy and X-Ray 
                         Diffraction techniques to characterize the surface reflectance 
                         spectra and mineralogical composition, respectively. ASTER land 
                         surface emissivity in addition to GOES, MODIS and Landsat-8 land 
                         surface temperature (LST) were also used. Results showed that the 
                         spectral features of the Atacama soil and the characteristics of 
                         this geographical zone, which is featured as the most hyper-arid 
                         and cloudless place in the world, make this area a potential 
                         target for surface reflectance characterization. Day and night LST 
                         comparison between field and remote sensing data are lower than 2 
                         K and the Root Mean Square Error for land surface emissivity is 
                         close to 2%. This work opens the possibilities to consider the 
                         Atacama Desert as a reference target for calibration and 
                         validation activities for earth observation missions' purposes.",
