The spatio-temporal heterogeneity of in-ground wood decay risk is important to service life planning of timber components. The integration of service life planning of timber with remote-sensing data services shows promise. Soil moisture and temperature data from the ERA5-Land repository were extracted for Europe over a 9 × 9 km point grid, between January 1993 and December 2022. The data were then appropriately scaled and used as input to an in-ground wood decay dose–response model. The resulting hazard map plotted dose to indicate annual in-ground wood decay risk, as a function of exposure to daily soil temperature and soil moisture conditions. Regions with low decay risk reflected temperature-limiting, oxygen-limiting or moisture-limiting soil conditions, all of which are unsuitable for fungal decay processes. Temporal investigations of the processed data revealed fungal growth windows influenced by seasonality.
