Czech Drought Monitor System for monitoring and forecasting agricultural drought and drought impacts [PDF]

International Journal of Climatology, 2020
AbstractThe awareness of drought and its impacts on Central Europe increased after the significant drought episodes in 2000, 2003, 2012 and 2015, which were all estimated to have caused over 500 million Euro in damage in the Czech Republic alone. These events indicated the need for timely and high‐resolution monitoring tools that would enable analysing,
