Degradation analyses of empirical inferential predictors for the development of improved dynamic mechanistic/empirical equations
… techniques, including principal component analyses, decision trees, random forests, gradient boosting, neural networks and partial least squares, to optimize the prediction accuracy and process control. By leveraging these models, the study aims to enhance the automation and optimization of …

Temporal assessment of volatile organic compounds at a site with high atmospheric variability in the North–West Province
… to 120ºC to remove O3 that could lead to sample degradation. Analyses of the sampled adsorption tubes were conducted by thermal desorption, cryofocusing, re-desorption, followed by gas chromatography separation and analysis with a mass selective detector (GC-MS). The results indicated that …

Impacts of model-data uncertainties on biogeophysical-biogeochemical interactions in a land surface model (with an emphasis on the northern high-latitude regions)
… on historical permafrost area, temperature, and degradation rates in the northern high-latitudes (45—90oN), and (2) compare the relative impact of these improvements with modeling uncertainties due to climate, and land-use and land-cover change datasets. Specifically, by incorporating deep soils, …
