VS-OSCILLOCSOPE ONLIE: WEB-APPLICATION OF PROCESS-BASED VAGANOV-SHASKIN MODEL FOR TREE-RING GROWTH

Abstract

The efficiency of the process-based Vaganov-Shashkin model for tree-ring growth simulation has been tested previously on extensive dendrochronological material from the Northern Hemisphere in USA, China, Russia, Tunisia, Spain and France. But using the model is not a trivial task, taking into account a number of the model parameters that should be adjusted for the certain environmental conditions based on parameterization approach. Here we present a new web tool of the VS-model parameterization, i.e. VS-Oscilloscope online, which can be used any computer platform due to the universal internet technologies. The software was tested on different datasets, and results of the web simulation were identical to the modeling based on previous version of parameterization – VS-Oscilloscope as a benchmark. It provides researchers an opportunity to use the complex model for visual simulation, reconstruction and forecast realistic tree-ring growth based on daily climatic conditions.
