                         monitoring requires the image transformation to ground reflectance 
                         through atmospheric correction. The most difficult parameter to 
                         obtain for the atmospheric correction is the horizontal 
                         visibility. The objective of this paper is to present the 
                         comparison of atmospheric correction of OLI Landsat 8 images using 
                         horizontal visibility from field inspection and from airport data. 
                         OLI images were acquired from three dates, 02/26/2014, 02/10/2014, 
                         10/11/2015 and 04/20/2016 and field work was conducted at the same 
                         time of satellite overpass and horizontal visibility was obtained 
                         by observing target at different distances and recording the 
                         maximum distance at which targets could be identifiable by visual 
                         inspection. Horizontal visibility was also downloaded from the 
                         Gale{\~a}o airport data, to which the obtained values were 10km 
                         as this is the maximum value recorded for this airport. 
                         Atmospheric correction was carried out for the two sources of 
                         horizontal visibility using the Atmcor4OLI program, adapted 
                         through the 6S code. The comparison between the two methods was 
                         through graphs of surface and apparent reflectance for typical 
                         targets and by a statistic test. The results show that the 
                         atmospheric correction is necessary to analyze the spectral 
                         response of the targets. The visibility of the airport yield 
                         surface reflectance different from the correction with field 
                         obtained data, mainly for clear atmospheres, while for visibility 
                         close to 10km the difference was smaller. It is concluded that an 
                         accurate source of horizontal visibility is key for obtaining 
                         correct surface reflectance values.",
