“The brewing process includes several steps: malting, milling, mashing, lautering boiling, fermenting, conditioning, filtering and packaging. The fermentation step is critical to the final beer quality because a multitude of factors (e.g. temperature, pH, sugar composition, yeast type) can affect a large number of quality parameters.” (Grassi et al., 2013)

“The NIR spectroscopy has been used to measure the content of various constituents in dairy products such as milk, milk powder, whey, and cheese” (Tsenkova et al., 1999)“The composition of produced milk has great value for the dairy farmer. It determines the economic value of the milk and provides valuable information about the metabolism of the corresponding cow. Vis/NIR transmittance spectra of the milk samples gave accurate fat and crude protein predictions (R2 > 0.90) and useful lactose predictions (R2 = 0.88).” (Aernouts et al., 2011)“Contents of main components (e.g. fats, proteins, and carbohydrates) are one of the important factors for the quality of milk powder; NIR spectroscopy is a feasible way for the components determination of the milk powder based on the NIR spectra.” (Wu et al., 2008)“…predictors based on NIR scans are much better than predictors based on age for content of the free amino acids important for cheese ripening.” (Feten et al., 2007)“Governmental or other official laboratories for quality control of dairy products can use NIRS as a screening method for rapid analysis of the composition of unknown samples. Besides with NIRS, it might be possible to determine quality parameters where in the past no direct correlation with chemical or physical methods was apparent.” (Burns & Ciurczak, 2007)

Spectroscopic techniques such as near infrared (NIR) can be used as a physiological indicator for irrigation scheduling based on vine water demand, rather than relying on weather and/or soil moisture measurements, which do not consider the plant in the assessmentNIR can be used to analyze chlorophyll in grape wine leaves, sugar content, nutrients and carbohydratesThe use of NIR has been reported as a tool to measure physical properties such as firmness, elasticity, and touch resistance in batches of Cabernet Franc grapes (LeMoigne n = 84 et al., 2008)The method based on NIR spectroscopy has been used to discriminate ripening, parcel effects, predict ripening stages, and parcel type (LeMoigne et al., 2008)Investigations of whole grape berry presentation using a NIR spectroscopic device indicated that NIR may have potential for use at the weighbridge or for in -field analysis of total anthocyanins (color), TSS and pH (Cozzolino et al.,2004)Studies have revealed the potential of NIR spectroscopy to predict the concentration of and monitor the extraction and evolution of phenolic compounds during red wine fermentation (Cozzolino et al., 2006)

"Albedo, the ratio of incoming to reflected solar radiation, plays an important role in climate by regulating the amount of shortwave radiation reflected or absorbed and subsequently reradiated as longwave radiation by a surface.” (Burakowski et al., 2015). Albedo changes are related to light scattering which is caused by changes in particle (crystal size) packing density and foreign materials such as algae or dust on the snow; these things impact the melt rate and can be an indicator of snow/water equivalent, which is important for reservoir management.. .

The value of Full-Range Spectroradiometers for measuring Solar Spectral Energy:. Many climate and surface energy balance studies involve monitoring the direct, diffuse and total components of solar spectral irradiance as they relate to the Earth’s atmosphere and surface (ASD Inc., n.d.).Outdoors, the primary source of spectral irradiance is the sun. The diffuse radiation from the sky is found primarily in the visible and UV portions of the spectrum (ASD Inc., 2012).“Because the solar radiation on the sun-surface-sensor path in the 0.4–2.5 μm visible and near-IR spectral regions is subject to absorption and scattering by atmospheric gases and aerosols, hyperspectral imaging data contains atmospheric effects. In order to use hyperspectral imaging data for quantitative remote sensing of land surfaces and ocean color, the atmospheric effects must be removed.” (Gao et al., 2009)“Atmospheric turbidity generally inhibits reliable measures of vegetation and sometimes renders atmosphere-induced variations on canopy spectra to exceed those due to vegetation development. These effects make the accurate and quantitative translation of [vegetation indices] more difficult and complicated.“ (Gao et al., 2000)“The illumination and appearance of the solar/skydome is critical for many applications in computer graphics, computer vision, and daylighting studies. Unfortunately, physically accurate measurements of this rapidly changing illumination source are difficult to achieve, but necessary for the development of accurate physically-based sky illumination models and comparison studies of existing simulation models.” (Kider et al., 2014)“Radiance is normally obtained in the field by nadir measurement of specific ground targets, with incoming solar irradiance spectra typically acquired from coincident measurement of reflected energy flux from reference panels with known spectral and angular scattering properties.” (Peddle et al., 2001)
