It is created using DLR's Soil Composite Mapping Processor (ScMAP): SCMaP is a specialised processing chain for detecting and analysing bare soils/surfaces on a large (continental) scale. Bare surface and soil pixels are selected using a combined NDVI and NBR index (PVIR2) that optimises the exclusion of photosynthetically active and non-active vegetation. The index is calculated and applied for each individual pixel. Dataset for ScMAP: * All SoilSuite products are calculated based on the available Sentinel-2 scenes recorded between January 2018 and December 2022 in Europe. * The data package excludes all scenes with a cloud cover of > 80 % and a sun elevation of < 20 degrees. * The spectral composite products are calculated from the mean value after extensive removal of clouds, haze and snow effects at both scene and pixel level. * The spectral data products are available at a pixel size of 20 m and contain 10 Sentinel-2 bands (B02, B03, B04, B05, B06, B07, B08, B08a, B11, B12). ----------------------------- WMS: https://geoservice.dlr.de/eoc/land/wms Naming convetion - download, data at ftp SCOMP_S2_0028-0048_2018-2022_MAJA-PVIR_V1-13_MASK: SCOMP S2 - sensor 0028-0048 - tile ID 2018-2022 - start and end of the time period MAJA-PVIR - L2A input and spectral index V1-13 - SCMaP version MASK - product abbreviation pixel size: 20m CRS: ETRS89-extended / LAEA Europe coordinates more detailed info about product and methodology: https://download.geoservice.dlr.de/SOILSUITE/files/EUROPE_5Y/000_Data_Overview/SoilSuite_Data_Description_Europe_V1.pdf How to cite this document: Heiden, U., d’Angelo, P., Karlshoefer, P., Kuehl, K., 2025.

The MASK product aggregates simple landcover classes. (1) Bare surface occurrences: The value 1 stands for the bare surface occurrence class with pixels that are characterized by an alternation of vegetation and bare soil/surface. Especially areas used for agriculture fall into this mask. It should be noted that a pixel only get 1, if bare surface was detected at least 3 times in the time period to reduce noise in the data. (2) Permanent vegetation: The value 2 describes pixels with permanent vegetation such as coniferous forests and permanent grasslands and excludes areas with bare surface occurrences. As an example, a clear-cut in a forest could appear as value 1 and not value 2, if bare surface is detected at least 3 times. (3) Other surfaces: All other pixels receive the value 3, which collects pixels with permanent non-vegetation surface such as water bodies, urban areas, roads, etc.). pixel size: 20m SOILSUITE_SRC_EUR_P5Y | [*]_SRC.tif The Bare Surface Reflectance Composite (Mean) contains reflectance values scaled between 0 and 10.000. It represents the mean reflectance of all Sentinel-2 bare surface occurrences between 2018 - 2022 excluding urban areas, water bodies, clouds, haze, cloud shadows and snow. This product is one of the main inputs for spectral as well as digital soil mapping approaches pixel size 20m SOILSUITE_SRC-STD_EUR_P5Y | [*]_SRC-STD.tif The Bare Surface Reflectance Composite (Std Dev) contains the standard deviation of all Sentinel-2 bare surface reflectance occurrences between 2018 - 2022. It is scaled between 0 and 10.000 for each band and excludes urban areas, water bodies, clouds, haze, cloud shadows and snow. This product quantifies e.g. the spectral dynamic of soils, which might differ according to their physical and chemical properties and thus, can be taken as an additional characteristic of the soil. pixel size: 20m SOILSUITE_SRC-CI95_EUR_P5Y | [*]_SRC-CI95.tif The Bare Surface Reflectance Composite (95% Confidence) contains the half-width of the 95% confidence interval (CI) of the Bare Surface Reflectance Composite. A large confidence interval conveys large uncertainty in the SRC value and a small interval indicates a high degree of certainty. Thus, the visible stripes coincides with the lower number of valid pixels (see product SFREQ-VPC), which makes the SRC measurement less reliable. It can be used to filter out pixels with a very high uncertainty (large confidence interval) from the model generation and/or from soil parameter prediction. Very high uncertainty can be especially found at the edges of agricultural fields, where pixels are more affected by spectral mixtures and lower number of bare surface occurrences pixel size: 20m SOILSUITE_SFREQ-BSF_EUR_P5Y | [*]_SFREQ.tif (Band 1) The Bare Surface Frequency (BSF) is scaled between 0 and 1 and quantifies the ratio of bare surface occurrences over the total number of valid Sentinel-2 observations |Rbare|/|R| in the observed time period between 2018 - 2022. The BSF is comparable across the European continent. In agricultural areas, the BSF gives an indication about the intensity of use of agricultural soils. It also can show areas, where bare surfaces are not expected such as in eroded grassland areas or clear-cuts in forests. pixel size: 20m SOILSUITE_SFREQ-BSC_EUR_P5Y | [*]_SFREQ.tif (Band 2) The BSC is defined as the number of occurrences detected as bare surface between 2018 - 2022. It is not normalized to the total number of valid Sentinel-2 observations. The striping visible in the BSC product reveals the dependence of the pixel position on the Sentinel-2 ground track that can lead to almost double observations in overlapping orbits. Therefore, the resulting BSC is not comparable across the European continent and should just be taken as an additional per pixel statistical information.. pixel size: 20m SOILSUITE_SFREQ-VPC_EUR_P5Y | [*]_SFREQ.tif (Band 3) This VPC contains the total number of valid Sentinel-2 observations in the time period between 2018 - 2022 excluding cloud, haze, cloud shadow, snow, etc.. pixel size: 20m SOILSUITE_MREF_EUR_P5Y | [*]_MREF.tif The Reflectance Composite (Mean) contains reflectance values per band, scaled between 0 and 10.000. It represents the mean reflectance of all valid Sentinel-2 observations between 2018 - 2022. Valid observations include vegetation, bare and other surfaces and exclude clouds, haze, cloud shadows and snow pixel size: 20m SOILSUITE_MREF-STD_EUR_P5Y | [*]_MREF-STD.tif The Reflectance Composite (Std Dev) contains the standard deviation per band for all valid Sentinel-2 observations between 2018 - 2022, scaled from 0 to 10.000. The valid observations include vegetation, bare surfaces and other surfaces and it excludes clouds, haze, cloud shadows and snow. The product quantifies the spectral dynamic of all land cover types occurring in the images. As an example, it shows a higher standard deviation in agricultural areas compared to natural grasslands.
