             abstract = "The nature of the spectral interaction between radiant energy and 
                         the Earth's surface components is very important for the 
                         development of Remote Sensing techniques. One of the most 
                         effective ways to understand those interactions is through the 
                         measurement and analysis of the spectral reflectance of those 
                         components. The use of field ground reflectance data for the 
                         calibration of satellite imagery can be more accurate if the 
                         measurements are done using a radiometer whose field of view has 
                         similar dimensions to that of the satellite imaging system. Many 
                         modem spectral radiometers, based upon CCD technology, have made 
                         the field reflectance measurements easier owing to their 
                         portability, speed of data acquisition and reliability. To take 
                         advantage of these new capabilities and to fulfill the geometric 
                         and spectral requirements of the ground data, the Laboratory for 
                         Radiometry of the National Institute of Space Research 
                         (INPE/BRAZIL), developed the Airborne Data Acquisition System 
                         (SADA), that uses two SPECTRON SE-590 radiometers and an 
                         helicopter as its operational platform. The SADA system is able to 
                         collect ground reflectance spectra at high sampling rates and over 
                         extensive or unaccessible targets such as water bodies and 
                         forests. The first operational test of the system was carried out 
                         on the Barra Bonita reservoir at the S{\~a}o Paulo State. In this 
                         experiment the SADA was used for the measurement of the 
                         bidirectional spectral reflectance factors of the different water 
                         masses of the reservoir. The results of this test showed that the 
                         system has an excellent operational flight performance and is very 
                         effective for the quick collection of field reflectance data over 
                         this kind of target.",
