abstract = "The first tests of the Goniometer by LaRaC (Laborat{\'o}rio de
Radiometria e Caracteriza{\c{c}}{\~a}o de Sensores
Eletro{\'o}pticos) are presented, with focus on its equipments
functionality. First results showed anomalous behavior of the
reflectance factor spectrum of a reference panel obtained at the
end of a BDRF data colleting cycle. Since this, exploratory
measurements were conduced to identify possible changes in the
Spetroradiometer and light source behaviors during its warm up
period. To investigate more precisely the influences of each
equipment, individuals warm up tests were made, whose results
indicated higher variations in the radiance spectral data due to
changes in spectroradiometer functionality, meanly in wavelengths
regions associated with the detector overlap regions (i.e. 1000 nm
and 1800 nm). It was observed that the spectroradiometer achieves
reasonable stability after a warm up period of 2,0 h, while the
light source showed low variability. In order to verify possible
correlations between data variability and environmental
parameters, a thermo hygrometer was used to collect data related
to these parameters, such as temperature and gases concentration,
at the same time as the tests were made, whose results showed no
correlation between them. Finally, data in a wavelength band was
selected from individual tests to compare radiance in band data to
spectral radiance data and, as result, the same behavior was
observed in both data.",
