um insumo promissor na aplica{\c{c}}{\~a}o dos estudos do meio
f{\'{\i}}sico relacionados ao regime de radia{\c{c}}{\~a}o

distribui{\c{c}}{\~a}o da radia{\c{c}}{\~a}o solar incidente
na superf{\'{\i}}cie terrestre e dos poss{\'{\i}}veis
condicionates de sua varia{\c{c}}{\~a}o ainda {\'e} pouco
explorado. O objetivo deste estudo foi experimentar o c{\'a}lculo
da distribui{\c{c}}{\~a}o da radia{\c{c}}{\~a}o solar
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
n{\'{\i}}veis t{\'{\i}}picos e padr{\~o}es gerais de
varia{\c{c}}{\~a}o da radia{\c{c}}{\~a}o solar incidente na
superf{\'{\i}}cie terrestre calculada em per{\'{\i}}odos
di{\'a}rio, mensal, semestral e anual, em tr{\^e}s {\'a}reas de
topografia variada, localizadas nas regi{\~o}es equatorial,
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
nublado em compara{\c{c}}{\~a}o com os valores \emph{default}
do algoritmo e com medidas obtidas de piran{\^o}metros. Por fim,
dados de produtividade de uma {\'a}rea de plantio de
\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
per{\'{\i}}odo de an{\'a}lise (di{\'a}rio, mensal, semestral,
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.",
