abstract = "This work presents the preliminary results of the first field
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.",
