Spectral Irradiance and Phytoplankton Community Composition In Blackwater Estuaries
… research examined relationships between spectral irradiance (water color) and phytoplankton community composition in blackwater habitats. Spatial and temporal variability in water color and phytoplankton community composition were examined in two South Carolina estuaries: Winyah Bay and …

Comparison and Investigation of Solar Spectral Irradiance with Solar Aspect Monitor
… from energetic particles and out-of-band irradiance is, however, present. The broadband (BB) technique is developed for isolating the 0.1 to 7 nm integrated irradiance to produce broadband irradiance. The results agree with the zeroth-order product from the EUV SpectroPhotometer (ESP) with …

Assessing Broadband and Spectral Irradiance Variability for Solar Nowcasting Using Statistical Analysis and Machine Learning
… a statistical assessment of high resolution spectral and broadband solar irradiance in Ottawa, Canada. The statistical assessment investigates the first- and second-order spectral and temporal dependencies of irradiance time series within the context of stationarity. The temporal structures …

Quantifying the stimuli of photorheological fluids
… from first principles, the model relates the irradiance of light source to the evolution of the concentration of a photoactive species within a sample. We show that the limiting time scale of the dynamics is the rate of photon delivery from the light source. Therefore, we recommend reporting …

White Light Continuum for Broadband Nonlinear Spectroscopy
… The ability to generate a high-quality, high-spectral-irradiance source of radiation confined in a single beam that spans the visible and near-infrared spectral regimes has great utility for nonlinear measurement methods such as the Z-scan technique. Using a broadband WLC instead of …

Thermal and Optical Properties of Oxide Coatings for High-Temperature Applications
… to thermal radiation up to 3 – 6 microns, the spectral range over which radiation from objects over 1000 °C predominately occurs. Consequently, over this broad-band spectral region, which I term the ‘thermal radiation window’, these refractory materials do not absorb thermal radiation and hence …

Changes in shortwave solar radiation under local and transported wildfire smoke plumes: implications for agriculture, solar energy, and air quality applications
… by 10 percentage points when smoke is present. Spectral analysis of clear-sky days shows smoke increases DF (average: +45%) and decreases total irradiance (average: −6%) across six wavelengths measured from 368 to 870 nm. Optical depth measurements from ground and satellite observations both …
