             abstract = "The reflectance-based approach is a calibration method in which 
                         in-situ radiometric measurements of a selected target on the Earth 
                         surface and atmospheric parameters are used as input into a 
                         radiative transfer model for estimating a top-of-atmosphere (TOA) 
                         radiance. However, an estimate of the TOA radiance is incomplete 
                         unless complemented with its uncertainty. This work described a 
                         methodology for predicting TOA radiance with an associated 
                         uncertainty. Two different methods of uncertainty propagation were 
                         applied: ISO GUM and Monte Carlo. In both methods the TOA radiance 
                         was calculated using the atmospheric radiative transfer code 
                         MODTRAN. Vicarious calibration data collected on August 21st, 2014 
                         at Atacama Desert, Chile and on July 25th, 2014 at Lu{\'{\i}}s 
                         Eduardo Magalh{\~a}es, Brazil were used to evaluate the 
                         methodology. The results, for the wavelength between 350 to 
                         2400nm, showed that using an agricultural area covered by soil 
                         surface (Brazil) the final uncertainty of the TOA radiance ranged 
                         from 1.0% to 9.2%; and using a desert surface (Chile) the final 
                         uncertainty ranged from 0.7% to 4.5%. The results also showed that 
                         the overall uncertainty using Monte Carlo simulations were smaller 
                         than the root sum of squares of each parameter (ISO GUM), 
                         suggesting that there is correlation among some parameter that is 
                         not take into account when the data are considered independent.",
