Agro-climatic Factors of Pilsen Region

Bc. Jiří VALEŠ

Master's thesis

Abstract:

This thesis aims to create large-scale calculations of agro-climatic factors from global climatic data with high granularity. I use freely available climatic data ERA5-Land from the Copernicus Climate Change Service as input climatic data. I describe related calculations and visualizations of agro-climatic factors. I delineate the created procedures, algorithms, and visualizations for the Pilsen region. Created agro-climatic factors are frost dates, frost-free periods, growing degree units, heat stress units, number of growing days, number of optimal growing days, dates of fall nitrogen application, precipitation, evapotranspiration, and runoff sums, water balance - changes in storage or differences between precipitation and evapotranspiration. Procedures are useable anywhere else in the world, especially in temperate and subtropical zones.
