Remote Sensing and Reflectance Profiling in Entomology [PDF]

open access: bronzeAnnual Review of Entomology, 2016
Remote sensing describes the characterization of the status of objects and/or the classification of their identity based on a combination of spectral features extracted from reflectance or transmission profiles of radiometric energy. Remote sensing can be benchtop based, and therefore acquired at a high spatial resolution, or airborne at lower spatial

Modelling Remote Sensing Reflectance to Detect Dispersed Oil at Sea. [PDF]

open access: yesSensors (Basel), 2020
This paper presents a model of upwelling radiation above the seawater surface in the event of a threat of dispersed oil. The Monte Carlo method was used to simulate a large number of solar photons in the water, eventually obtaining values of remote sensing reflectance (Rrs).
