| | 1 | === 4.1 USDA soil orders === |
| | 2 | We use the USDA soil order map of Sun et al. (in revision) with the dominant soil order per pixel. The gap filling of the missing values was done like this |
| | 3 | (see script /home/users/dgoll/ORC_data/USDA_soilorders/try_2_fill/fill_deserts.ksh): |
| | 4 | |
| | 5 | We use the soiltext class 6 for cold desert from the input file "soils_param.nc" to fill missing values in these region with Gelisols (5). |
| | 6 | After we set cold desert, we use the level 1 of the maxvegetfrac in the input file "PFTmap.nc" to fill missing values of the remaining desert to Aridisols (2). Hereby, we use a threshold of 0.8 for identifying deserts in maxvegetfrac. |
| | 7 | |
| | 8 | In case of the remaining missing points, mostly coast line points, ORCHIDEE will assign the value of the nearest neighbour in the routine "get_soil_orders" in src_stomate_io.f90. |

| | 13 | === 4.2 GliM lithology === |
| | 14 | We use the GliM lithology map by Hartmann & Moosdorf (2012). We account for subgrid scale heterogeneity by reading the fractional coverage of each of the 16 classes. |

| | 17 | Figure 2: GliM lithology: the dominant type with a fractional cover of >0.51 ! alphabetical sequence of lithological classes: |
| | 18 | ! ! 0 - no dominant type |
| | 19 | ! ! 1 - evaporites |
| | 20 | ! ! 2 - ice & glaciers |
| | 21 | ! ! 3 - metamorphics |
| | 22 | ! ! 4 - no data |
| | 23 | ! ! 5 - acid plutonic rocks |
| | 24 | ! ! 6 - basic plutonic rocks |
| | 25 | ! ! 7 - intermediat plutonic rocks |
| | 26 | ! ! 8 - pyroclastics |
| | 27 | ! ! 9 - carbonate sedimentary rocks |
| | 28 | ! ! 10 - mixed sedimentary rocks |
| | 29 | ! ! 11 - siliciclastic sedimentary rocks |

| | 36 | === 4.4 Soil shielding (Hartmann et al. (2014) === |
| | 37 | The factor corrects the weathering flux where the active zone in the soil is disconnected from the bedrock. |
