Table 1 Datasets use in the present experiment
Abbreviation | Number of sites | Description |
|---|---|---|
LEG-SOC94 | 302 | Data of measured topsoil SOC collected in the 1994 in land use CORINE 2.1 also used in [56] after a normalization procedure for depth. See further for explanation of the normalization process |
EST-SOC08 | 302 | Data of estimated topsoil SOC in land use CORINE 2.1 extracted in the coinciding location of the LEG-SOC94 after the BRT modelling built with samples taken in 2008 and provided in [56] |
SOC94 | 30 | Random samples from the LEG-SOC94 in land use CORINE 2.1 after control for stability of land use until the 2017. See further for explanation of the strategy to establish the number of samples and location |
SOC17 | 30 | Samples taken in April 2017 in coinciding locations of the C94 |
EST-SOC08- LEG-SOC94 | 302 | Differences between data estimated in 2008 in the same locations of data collected in 1994 |
SOC17- SOC94 | 30 | Differences between data measured in 2017 in the same locations of data selected in 1994 |
