Near UV and visible electromagnetic radiation have significant influence on filter paper made only from virgin fibres without any additives (calcium carbonate, clay, dye, starch, pigment) decrease
reflectance value of those papers, especially in blue part spectra.
Reflectance is the ratio of light that radiates onto a surface to the amount reflected back.
A high
reflectance over a broad spectral range of 250-2500 nm increases optical efficiency.
When Landsat-type images are concerned, a logical way is to transform all images into surface-level
reflectance factor units.
Over the lifecycle of the pavement, the pavement material matters substantially more than the pavement
reflectance," explains Ronnen Levinson, a researcher in Berkeley Lab's Heat Island Group.
Part one of our study explores how tornadoes affect the
reflectance and commonly used indices derived from
reflectance, such as the Normalized Difference Vegetation Index (NDVI) and the Tasseled Cap indices of brightness, greenness, and wetness, when comparing damaged forest, grassland, and urban land cover.
Within this context, the objective of this study was to characterize the variability of spectral
reflectance and temporal profiles of vegetation indices associated with nitrogen fertilization, crop cycle periods, and predominating weather conditions during the winter canola growing season in southern Brazil.
Solar
reflectance values are typically >80% for coatings formulated specifically as "cool" roof paints, which means they absorb and/or transfer <20% of the incident energy.
The chlorophyll content was shown to increase gradually and continuously, regardless of trends in leaf
reflectance.
The 850 model is reportedly the only truly close-tolerance spectrophotometer for both
reflectance and transmission measurement, ensuring customers can confidently communicate color digitally throughout their supply chain.
2014) proposed a new spectral ratio index in the near infrared (NIR) shoulder region (NSRI), defined by a simple ratio of
reflectance at 890 nm to
reflectance at 780 nm, for assessing leaf structure deterioration.
This microstructure has been found to transform a transparent film into an opaque film with high diffused
reflectance.
