TheMonk Skin Tone (MST)Scale was developed by Dr. Ellis Monk at Harvard and is comprised of 10 different tones. The scale is currently being used byGoogle Researchand is designed to represent a broader range of geographic communities than the commonly usedFitzpatrick scale, which is skewed towa...
Radiance Watt/steradian/m2 Lumiance cd/m2 Footlambert Irradiance Watt/m2 Illuminance Lux Footcandle A perfectly diffuse source has a lambertian surface and reflects light in all directions following the cosine law. A white piece of paper and a piece of opal glass are examples of good diffusers....
Not really. A Whitted ray tracer is only doing direct lighting normally. You would need to implement a proper light transport algorithm to get the correct result. Everything else would again be rasterizer tricks like rendering to cubemaps for reflections, irradiance caching, voxel lighting, etc....
PLT file is a MODTRAN spectral output file containing just two columns of data, with a spectral grid in the first column and either transmittance, radiance or irradiance in the second column. PLT format description Info Link Category: Data files Application: MODTRAN Mime-type: application/...
LEDAPS first converts digital number (DN) values to at-sensor radiance, which is then converted to TOA reflectance based on solar zenith angle, Earth-Sun distance, bandpass, and solar irradiance. Finally, atmospheric correction routines based on 6S radiative transfer algorithm [76] convert at-...
The phenomenology of photosynthesis is discussed in terms of living beings on Earth, aiming to obtain a generalized picture of “Life”. Section 3 addresses the observational and theoretical work on oceanic photosynthesis and its interaction with the ocean environment. The report concludes with a ...
Where there is only one emitting source with no other light sources in the environment, it is under some circumstances possible to convert from the spectral radiance to the corneal irradiance if distance and spatial extent are known. Spectra are physical and the most "complete" representations of...
However, since the goal is to develop a model applicable to Sentinel-2 data sensors, during the geo-rectification, the outputs were up-scaled to 20 m spatial resolution. The Pika Hyperspectral sensor initially records the sunlight radiance in digital numbers (DN). Equation (1) was thus used...
2.1. Modeling We use the limited area model WRF-Chem in a two-way nesting configuration in order to describe the physical processes at various atmospheric scales. The grid-space for the external domain is set at 12 × 12 km. An intermediate domain at 3 × 3 km is used over Crete and ...
