This study has, for the first time, analyzed in detail the risk occurrences of the last spring frost, first fall frost, and the length of the frost-free period during the growing season of vegetable crops at a high horizontal resolution of 10 km (CZGRIDS, ALADIN-Climate/CZ) in the Elbe River lowland. The daily minimum air temperature from 116 grid points throughout the studied area for the period 1961-2011 was used. The daily values of minimum air temperature ranges of 0 degrees C to1.1 degrees C,1.2 degrees C to2.2 degrees C, and below2.2 degrees C were considered to constitute mild, moderate, and severe frosts intensities, respectively. Firstly, comprehensive analysis of the spatio-temporal variability of the date of the last spring frost, the date of the first fall frost, and the length of the frost-free period in the Elbe River lowland were provided. Secondly, a catalogue of the mean dates of the spring and fall frosts for the three frost severities (mild, moderate, and severe) and degrees of earliness (early, mean, and late ending/ beginning), as well as the length of the frost-free period over the Elbe River lowland, was developed. Thirdly, to identify the areas with high-risk occurrences of damaging last spring frosts during the sowing/ planting period of vegetables in the Elbe River Lowland.
