Comparison of Methane Plume Detection Using Shortwave and Longwave Infrared Hyperspectral Sensors Under Varying Environmental Conditions [PDF]

, 2022
Methane is a prevalent greenhouse gas with potent heat trapping capabilities, but methane emissions can be difficult to detect and track. Hyperspectral imagery is an effective method of detection which can locate methane emission sources in order to ...

Spatial resolution, spectral metrics and biomass are key aspects in estimating plant species richness from spectral diversity in species‐rich grasslands [PDF]

, 2022
Increasing evidence suggests that remotely sensed spectral diversity is linked to plant species richness. However, a conflicting spectral diversity–biodiversity relationship in grasslands has been found in previous studies.
