VS-Growth Evolutional Neural Network (VS-GENN)

This is a Web Platform of Experimental and theoretical analysis of the tree-growth variability in forest ecosystems of Northern Hemisphere (This project is supported by the Russian Science Foundation and the Russian Ministry of Science and Higher Education)

About the project


The goal of the project is a retrospective assessment and short-term forecast of the productivity of woody plants in the principal forest species of boreal zones in Northern Hemisphere under the influence of principal climatic (solar irradiance, temperature and precipitation) and non-climatic (fires, floods, insects outbreaks, etc.) factors based on the original process-based simulation model of tree growth and specially developing neural network platform.

Parametrization

Automatic parameterization of the VS-model using genetic and differential evolutionary strategies.More details

Soil moisture 

Improvement of the soil moisture block in the VS-model based on new approaches developed by the author's team of the project.

Classification

Classification of the territory covered by a network of dendrochronological sites, based on standardized tree-ring chronologies.

Integration 

Integration of sets of optimal VS-model parameters into an interactive dendroclimatic monitoring system.
