Global soil type dataset for WRF-ARW model, based on HWSD version 2

Global soil type dataset, based on HWSD ("Harmonized World Soil Database", version 2.0), suitable for meteorological model WRF-ARW. spatial resolution: 30 arc seconds by 30 arc seconds (about 1km) original data (HWSD 2.0) https://s3.eu-west-1.amazonaws.com/data.gaezdev.aws.fao.org/HWSD/HWSD2_RASTER.zip https://s3.eu-west-1.amazonaws.com/data.gaezdev.aws.fao.org/HWSD/HWSD2_DB.zip https://gaez.fao.org/pages/hwsd documentation: Nachtergaele, Freddy, et al. Harmonized world soil database version 2.0. Food and Agriculture Organization of the United Nations, 2023. https://www.fao.org/3/cc3823en/cc3823en.pdf the original 7 soil layers (0–20 cm, 20–40 cm, 40–60 cm, 60–80 cm, 80–100 cm, 100–150 cm and 150–200 cm) have been remapped to the 2 layers required by WRF (topsoil 0-30 cm, botsoil 30-200 cm) the original Soil Mapping Units (SMU) have been remapped to the 16 soil categories used by WRF: the depth-weighted averages of the content of clay, silt and sand lead to 12 texture-based categories (Sand, Loamy sand, Sandy loam, Silt loam, Silt, Loam, Sandy clay loam, Silty clay loam, Clay loam, Sandy clay, Silty clay, Clay), as defined by USDA; category "Organic material" is assigned where the average content of organic carbon exceeds the threshold of 25%; where the content of clay, silt and sand is not defined, HWSD special categories are mapped to the WRF last 3 categories, as follows: "Water bodies" to "Water", "Rock outcrops" and "Rocky sublayers" to "Bedrock", "Land ice and glaciers", "Dunes/shifting sands", "Salt flats", and "Other" to "Other" The dataset is provided in two ways: two global files (SoilType_depth<T>to<B>cm.tif), one for each layer; 16 tiles, 8 for each layer, each covering 90 degrees by 90 degrees (SoilType_depth<T>to<B>cm_lon<W>to<E>deg_lat<S>to<N>deg.tif). The format of the files is GeoTIFF, compatible with convert_geotiff, a commandline utility for converting data from GeoTIFF to geogrid format used by WRF. Soil categories are coded as follows code category 1 sand 2 loamy sand 3 sandy loam 4 silt loam 5 silt 6 loam 7 sandy clay loam 8 silty clay loam 9 clay loam 10 sandy clay 11 silty clay 12 clay 13 organic material 14 water 15 bedrock 16 other
