Turbulence penetration helps distinguish canopy density regimes
What the study found Canopy density was not fully captured by frontal density, a common measure of canopy density, for some canopy topologies. The authors found that turbulence penetration into canopies can be used to distinguish sparse, intermediate, and dense regimes. Why the authors say this matters The study suggests that measuring turbulence penetration directly…
SVM and Wishart classifiers performed almost identically
—
in EngineeringWhat the study found Support Vector Machine (SVM) and Wishart classifiers produced almost the same classification accuracy for land-cover mapping over metropolitan Hyderabad. The reported accuracies were 91.08% for SVM and 91.07% for the Wishart classifier. Why the authors say this matters The authors state that quantitative assessment of land use and land cover is…
Croplands cool nights but have mixed daytime effects in tropical Africa
Cropland expansion across tropical Africa produces nighttime cooling but hydroclimatically-dependent daytime effects, driven by turbulent heat flux changes tied to vegetation differences.
