Rayleigh corrected reflectance
WebMar 26, 2024 · The MOD09Q1 Version 6.1 product provides an estimate of the surface spectral reflectance of Terra Moderate Resolution Imaging Spectroradiometer (MODIS) Bands 1 and 2, corrected for atmospheric conditions such as gasses, aerosols, and Rayleigh scattering. Provided along with the 250 meter (m) surface reflectance bands are two … WebAdditionally Rayleigh corrected reflectance (rhorc_*) will be output for SPOT. SPOT bundles seem to have an extra level compared to Pléiades, and the directory containing the SPOT_VOL.XML file has to be provided.

WebFrouin and Pelletier (2015) construct a numerically efficient partitioning of the Rayleigh corrected, or “observed” spectral reflectance using a perfect binary tree. This partition is … Webestimated surface reflectance is different from the Rayleigh-corrected TOA reflectance, which is only a subtraction of the Rayleigh reflectance from the TOA reflectance and does not incorporate total transmission and the atmospheric backscattering ratio. Details of the SREM atmospheric correction method can be found in Bilal et al. [19].
WebJan 25, 2016 · Based on spectral analysis, differences in spectral characteristics were found over different underlying surfaces, which include land, sea, middle/high level clouds, stratus clouds and sea fog. Statistical analysis showed that the Rrc (412 nm) (Rayleigh Corrected Reflectance) of sea fog pixels is approximately 0.1-0.6. WebFirst, the spectral ratio of Rayleigh-corrected reflectance at two SWIR bands is used to derive the aerosol model or aerosol spectral shape. Once the aerosol model is …
WebNov 23, 2024 · Coarse-resolution sensors have been used operationally to monitor floating algal blooms with a near daily revisit in coastal and inland waters. Most of the current methods in estimating fractional floating algae cover (FAC) were based on the linear pixel un-mixing assumption. In this study, a new FAC model following a logistic curve was … WebAll data were corrected for the Raman and Rayleigh effects, using daily fresh deionized water signals, and for the inner-filter effect, using absorbance spectra. Moreover, because the low concentrations of Fe tot result in low total Fe:DOC molar ratios, of the order of 10 −2 , this suggested that the Fe effect on the absorbance and fluorescence of CDOM was …
