Wood harvesting and transport conditions, 1981-2099

This dataset is a part of FMI’s BioClimFMI gridded datasets produced mainly as a contribution of the Forbio-project. Datasets include derived climatological variables needed mainly in forestry and agricultural applications. In this dataset is given the mean annual number of days when soil frost and snow cover facilitate forest harvesting also from terrain types having low bearing capacity. The criteria is at least 20 cm of soil frost and/or at least 40 cm snow depth. The estimates have been calculated for the period 1981–2010 using observational data and for the periods 2021–2050 and 2070–2099 using climate scenarios under representative concentration pathways (RCPs) 4.5 (moderate emissions) and 8.5 (high emissions). The calculations were made for three soil/forest types: pine forest on peat land, pine forest on sandy soil and spruce forest on clay or silt soil. Spatial resolution (lon × lat) is 0.2° × 0.1°. This dataset is available as a text file. The method and the data used in creation of the dataset is described in the publication: Lehtonen, I., Venälänen, A., Kämäräinen, M., Asikainen, A., Laitila, J., Anttila, P. and Peltola, H., 2018.
