                         isso, foi realizado um estudo na Reserva Particular do 
                         Patrim{\^o}nio Natural, localizada no munic{\'{\i}}pio de 
                         Coruripe, Alagoas, no per{\'{\i}}odo de outubro/2009 a 
                         setembro/2010, baseado em observa{\c{c}}{\~o}es da PAR (2, 13, 
                         26 m) realizadas numa esta{\c{c}}{\~a}o micrometeorol{\'o}gica 
                         instalada em uma torre de 24 metros de altura (10° 00 37S, 36° 17 
                         60W, 160 m alt.). A PAR incidente e refletida, acima 
                         (PAR\↓_Ext e PAR\↑_Ext) e abaixo (PAR\↑_Spf) 
                         da floresta, seguem a sazonalidade imposta pelo movimento aparente 
                         do Sol, o que acarretou em maiores registros m{\'e}dios 
                         hor{\'a}rios de PAR na esta{\c{c}}{\~a}o seca, superiores a 600 
                         e 12 W m-2, e as menores na esta{\c{c}}{\~a}o chuvosa, 
                         inferiores a 300 e 8,0 W m-2, influenciadas pela presen{\c{c}}a 
                         da nebulosidade. Nas primeiras e {\'u}ltimas horas do 
                         per{\'{\i}}odo diurno, constataram-se registros de 
                         PAR\↑_Spf pr{\'o}ximos {\`a} zero. J{\'a} o oposto foi 
                         observado pr{\'o}ximo {\`a}s 12 h (novembro e dezembro), com 
                         aproximadamente 14 W m-2. ABSTRACT: The study of solar radiation 
                         is important to understand the several physical, chemical and 
                         biological processes that occur in the biosphere, particularly in 
                         the forest. The objective of this study has been to evaluate the 
                         temporal evolution of incident and reflected Photosynthetic Active 
                         Radiation (PAR) above and below the canopy of the Mata Atlantica 
                         forest. The study has been conducted in a Private Reserve Natural 
                         Heritage, located in the Coruripe city, Alagoas, during the period 
                         from October 2009 to September 2010, based on the PAR (2, 13, 26 
                         m) observations obtained at the micrometeorological station, 
                         installed on a 24 meters high tower (10° 17 36S, 36° 17 24W, 160 m 
                         asl). According to the results the incident and reflected PAR 
                         outside (PAR\↓_Ext and PAR\↑_Ext) and inside 
                         (PAR\↑_Spf) forest follow the seasonality imposed by the 
                         apparent motion of the Sun. The higher PAR values occur during the 
                         dry season, exceeding 600 and 12 W m-2, and during the wet season 
                         these averages was less than 300 and 8.0 W m-2, influenced by 
                         cloudiness. At the beginning and ending of sunlight time 
                         PAR\↑_Spf values near zero were measured. The opposite 
                         measurements of about 14 W m-2, around 12 h (November and 
                         December) were observed.",
