| 77 | | - soils_param.nc: '''Zobler map''' at 1° resolution, with 7 soil texture classes reduced in ORCHIDEE into three texture classes (coarse, medium, fine) |
| 78 | | - soils_param_usda.nc: '''Reynolds map''', at 5 arc-min resolution (1/12°), with 12 USDA texture classes directly usable in ORCHIDEE |

| 81 | | In branch 2.2 |
| 82 | | - soil texture of SoilGrids, converted from the 1km SoilGrids maps of %sand,silt,clay to the 12 USDA classes, and upscaled at two resolutions : soils_param_SoilGrids_5km.nc and soils_param_SoilGrids_halfdeg.nc |
| 83 | | - modified Reynolds soil texture map: the clay texture (nsc=12) is split in two classes, the swelling Clays which keep the class index 12 and the corersponding soil parameters, and the non-swelling Clays (Oxisols), corresponding to a new soil class 13, with new soil hard-coded parameters, (cf the [https://tel.archives-ouvertes.fr/tel-03110807/document PhD thesis of Salma Tafasca, 2020], chapter 4). |
| | 81 | In branch 2.2 (starting r6954), we've introduced the possibility to describe the soil properties with other maps : |
| | 82 | - ''soils_param_SoilGrids_5km.nc'' and ''soils_param_SoilGrids_halfdeg.nc'': the 1km SoilGrids maps of %sand,silt,clay have been converted to the 12 USDA classes, and upscaled at two resolutions : |
| | 83 | - ''soils_param_usda_with_clay_oxisol.nc'': modified Reynolds soil texture map, in which the clay texture (nsc=12) is split in two classes, the swelling Clays which keep the class index 12 and the corersponding soil parameters, and the non-swelling Clays (Oxisols), corresponding to a new soil class 13, with new soil hard-coded parameters, (cf the [https://tel.archives-ouvertes.fr/tel-03110807/document PhD thesis of Salma Tafasca, 2020], chapter 4). |
| | 85 | - ''hydrol_params_spmip_halfdeg.nc'': this file contains soil hydraulic parameters given by the SP-MIP team |
| | 86 | - ''hydrol_params_Zhang2018_halfdeg.nc'': ks, theta_s and theta_r are taken from Zhang et al. (2018), n and alpha are obtained using the SoilGrids_halfdeg.nc texture map and the Schaap et al. (2001) pedo-transfer function. NA is replaced with the parameters of the Loam class. More details in the PhD thesis of Salma Tafasca chapter 5, where this map is used in the simulation SIMUSOC2 |
| | 87 | - ''hydrol_params_with_porosity_Reynolds.nc'': contains soil hydraulic parameters derived from the Reynolds soil texture map, using the pedo-transfer function from Carsel & Parrish, except for porosity, which is taken from the porosity map of Reynolds et al. (2000). Field capacity and wilting point are also calculated based on this porosity. More details in the PhD thesis of Salma Tafasca chapter 5, where this map is used in the simulation SIMUSOC1. |
| | 88 | - ''hydrol_params_salma_SOC3.nc'': contains soil hydraulic parameters derived from soil texture (Reynolds + Carsel & Parrish 1988) and soil organic content (from an ORCHIDEE simulation described in Qiu et al., 2019). The construction of these maps is decribed in the PhD thesis of Salma Tafasca chapter 5, where this map is used in the simulation SIMUSOC3. |
