                         incidente na superf{\'{\i}}cie terrestre a partir de MDEs 
                         obtidos do \emph{Shuttle Radar Topography Mission} (SRTM) sob 
                         diferentes condi{\c{c}}{\~o}es topogr{\'a}ficas, 
                         atmosf{\'e}ricas e de localiza{\c{c}}{\~a}o. Foram estudados os

                         superf{\'{\i}}cie terrestre calculada em per{\'{\i}}odos 
                         di{\'a}rio, mensal, semestral e anual, em tr{\^e}s {\'a}reas de

                         tropical e subtropical. A radia{\c{c}}{\~a}o solar foi calculada 
                         com o algoritmo Solar \emph{Analyst}, sobre MDEs refinados do 
                         SRTM, obtidos do Topodata. Os par{\^a}metros atmosf{\'e}ricos 
                         foram testados para condi{\c{c}}{\~o}es de c{\'e}u claro a

                         \emph{Eucalyptus spp}. foram analisados para verificar sua 
                         rela{\c{c}}{\~a}o com os resultados de radia{\c{c}}{\~a}o 
                         solar. Os resultados gerais indicaram que a raz{\~a}o entre os 
                         n{\'{\i}}veis m{\'a}ximos e m{\'{\i}}nimos da 
                         radia{\c{c}}{\~a}o solar diminuiu com o aumento do

                         anual). A amplitude de radia{\c{c}}{\~a}o solar anual aumentou 
                         com o aumento da declividade, embora os n{\'{\i}}veis 
                         m{\'a}ximos tenham apresentado aumento discreto em 
                         compara{\c{c}}{\~a}o com a forte diminui{\c{c}}{\~a}o dos 
                         n{\'{\i}}veis m{\'{\i}}nimos. Foi verificado que os 
                         n{\'{\i}}veis de radia{\c{c}}{\~a}o solar anual m{\'e}dios, 
                         nas diversas combina{\c{c}}{\~o}es de declividade e 
                         orienta{\c{c}}{\~a}o de vertentes, diminu{\'{\i}}ram com o 
                         aumento da latitude. Esta redu{\c{c}}{\~a}o mostrou-se associada 
                         a um aumento da amplitude devido a uma redu{\c{c}}{\~a}o dos 
                         n{\'{\i}}veis m{\'{\i}}nimos. A integra{\c{c}}{\~a}o de 
                         par{\^a}metros atmosf{\'e}ricos moment{\^a}neos de diferentes 
                         localidades em per{\'{\i}}odos anuais gerou valores mais 
                         est{\'a}veis e mais pr{\'o}ximos ao \emph{default} do 
                         algoritmo. As simula{\c{c}}{\~o}es com estes par{\^a}metros 
                         mostraram que o aumento da nebulosidade ocasiona a 
                         redu{\c{c}}{\~a}o dos n{\'{\i}}veis de radia{\c{c}}{\~a}o 
                         solar anual no terreno, al{\'e}m de reduzir a amplitude relativa 
                         da varia{\c{c}}{\~a}o devida ao relevo. Os resultados da 
                         rela{\c{c}}{\~a}o entre a radia{\c{c}}{\~a}o solar anual e o 
                         crescimento de \emph{Eucalyptus SP}. indicaram 
                         varia{\c{c}}{\~a}o da produtividade de acordo com os 
                         condicionantes agron{\^o}micos esp{\'e}cie, espa{\c{c}}amento, 
                         solos e suas combina{\c{c}}{\~o}es. Entretanto, a 
                         distribui{\c{c}}{\~a}o dos dados de radia{\c{c}}{\~a}o solar 
                         nos talh{\~o}es se apresentou relativamente uniforme, o que 
                         n{\~a}o permitiu verificar de maneira conclusiva a 
                         correla{\c{c}}{\~a}o esperada. ABSTRACT: The use of Digital 
                         Elevation Models (DEMs) by remote sensing is a promising data in 
                         the application of physics environment studies related to solar 
                         radiation. However, the knowledge of incident solar radiation 
                         distribution at the Earth's surface and the possible variation 
                         constraints is still under explored. The aim of this study was to 
                         try the calculation of solar radiation distribution incident at 
                         the Earth's surface from Shuttle Radar Topography Mission (SRTM) 
                         DEMs with different topographic conditions, atmospheric and 
                         location. Were studied typical levels and general standards of 
                         solar radiation incidents in the Earth's surface calculated for 
                         daily, months, semesters and year period, for three studies sites 
                         with varied topography, located in the equatorial, tropical and 
                         subtropical areas. The Solar Analyst software package was used to 
                         compute solar radiation, with basis on refined MDEs, from database 
                         Topadata. The atmospheric parameters were tested with data varying 
                         from clear sky to cloudy conditions and it was compared to 
                         algorithm default values and pyranometer measurements. Finally, 
                         the productivity data of Eucalyptus spp. and solar radiation 
                         results were analyzed. The overall performance indicated that the 
                         ratio of the maximum and minimum levels of solar radiation 
                         decreased with the increasing periods (daily, monthly, biannual 
                         and annual). The annual solar radiation amplitude has increased 
                         when the slope increasing, although the maximum levels had showed 
                         slight increase compared with the strong decrease in minimum 
                         levels. The medium annual solar radiation levels decreased with 
                         the increasing of the latitude for all combinations of slope and 
                         aspect. This reduction was associated with increased amplitude 
                         because of decreasing minimum levels. The annual integration of 
                         atmospheric parameters from different areas generated stable 
                         values and similar to algorithm default. The nebulosity causes a 
                         decreasing annual solar radiation levels at the surface and 
                         reduces the solar radiation variation due to the relief. The 
                         relationship between annual solar radiation and Eucalyptus spp. 
                         growth indicated productivity variation according to the 
                         conditions agronomic, species, distance, soils and combinations of 
                         these variables. However, the solar radiation distribution at the 
                         eucalyptus stands was relatively uniform, because of that was not 
                         possible to verify the expected correlation.",
