The SoilSuite contains a collection of different image data products that provide information about the spectral and statistical properties of European soils and other bare surfaces such as rocks. It is created using DLR's Soil Composite Mapping Processor (ScMAP), which utilises the Sentinel-2 data archive.

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. 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).

The SoilSuite comprises:

• "Mask" is a product that aggregates simple landcover classes that occur during the time period between 2018 - 2022 (Sentinel-2). The three-class Mask contains bare surface occurrences (1), permanent vegetation (2) and other surfaces such as water bodies, urban areas, roads (3).
• "Bare Surface Reflectance Composite - Mean" that provides the spectral properties of soils that vary due to different soil organic carbon (SOC) content, soil moisture and soil minerology. This product is often used for spectral and digital soil mapping approaches
• "Bare Surface Reflectance Composite - Standard deviation" informing about the spectral dynamic of bare surfaces and soils
• "Bare Surface Reflectance Composite - 95% Confidence" contains information about the reliability of the spectral information due to the number of valid observations per pixel
• "Bare Surface Frequency Product" provides the number of bare soil occurrences over the total number of valid observations (Band 1)
• "Bare Surface Count Product" provides the number of bare soil occurrences (Band 2).
• "Valid Pixel Count Product" provides the total number of valid observations (Band 3)
• "Reflectance Composite - Mean" represents the mean reflectance of all valid Sentinel-2 observations between 2018 - 2022 including vegetation, bare and other surfaces
• "Reflectance Composite - Standard deviation", which contains the standard deviation per band for all valid Sentinel-2 observations between 2018 - 2022.
