                         Satellite Fire Data Data from satellites are very important for 
                         providing information on vegetation fires worldwide. Despite of 
                         the broad spatial and temporal coverage, there are several factors 
                         that complicate the interpretation of these data. Examples of 
                         these factors include fires occurring at times different than the 
                         satellite overpasses, the presence of clouds, fires occurring 
                         under plant canopies, small fires, and very reflective surfaces. 
                         In order to enhance the interpretation of satellite fire data, we 
                         are in the process of collecting groundbased data on fires, and 
                         relating these data to corresponding information from satellite 
                         fire products. Ground-based data are collected using a simple and 
                         passive method that allows for a large sample size. One method for 
                         data analysis is the construction of error matrixes, which can 
                         provide statistics on inclusion (commission)and exclusion 
                         (omission)errors in satellite fire data. In this work we present 
                         results from fieldwork in areas close to Marab{\'a}, Brazil, 
                         where about 90 fires were observed during November 3 to 5, 2001. 
                         These results include fires position, time, size, type of 
                         vegetation burned, cloudcover, and statistics on inclusion and 
                         exclusion errors in related remote-sensing fire data. Preliminary 
                         analyses suggest that errors of omission are larger than errors of 
                         commission, and are dominated by satellite overpass times, 
                         cloud-coverage and fire size. Potential strategies to correct for 
                         these errors are discussed.",
