                         forest during the dry season, an experiment was effected in 
                         Central Amazonia. Thus, the temperatures in three heigths and 
                         several radial depths of 4 stems of dominant species among the 670 
                         trees of an 1 hectare site selected at the Esta{\c{c}}{\~a}o 
                         ZF-2 (02°3645{"} S, 60°1240{"} W), plus the air temperatures and 
                         moistures, were measured. To compute the RES, all components which 
                         store energy during the day were considered: litter, minor 
                         components (palm trees and lianas), stem, branches, twigs, leaves 
                         and air. To obtain the RES of the stems, three methods were used. 
                         The first one uses all stem temperature measurements. The other 
                         ones, which are based on an analytical solution of the heat 
                         conduction equation, depend only on the temperature measurements 
                         in one radial depth of a tree with the average characteristics of 
                         the complete set. The RES of the other components was determined 
                         with the air and the average tree stem surface temperature 
                         measurements, plus the air moisture. One third of the RES of the 
                         forest is due to the stems, while other third is due to the air; 
                         finally, the last one is divided among the other parts. During the 
                         night and the transition periods, the RES of the forest (S) may 
                         constitute a sizable fraction of the net radiation (Rn), or even 
                         exceed it. On a daily basis, the values of S were observed between 
                         1 and 10% of Rn, depending on the weather conditions.",
