| 71 | | === 4.1 USDA soil orders === |
| 72 | | 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 |
| 73 | | (see script /home/users/dgoll/ORC_data/USDA_soilorders/try_2_fill/fill_deserts.ksh): |
| 74 | | |
| 75 | | 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). |
| 76 | | 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. |
| 77 | | |
| 78 | | 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. |

| 83 | | === 4.2 GliM lithology === |
| 84 | | 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. |
| 85 | | |

| 87 | | Figure 2: GliM lithology: the dominant type with a fractional cover of >0.51 ! alphabetical sequence of lithological classes: |
| 88 | | ! ! 0 - no dominant type |
| 89 | | ! ! 1 - evaporites |
| 90 | | ! ! 2 - ice & glaciers |
| 91 | | ! ! 3 - metamorphics |
| 92 | | ! ! 4 - no data |
| 93 | | ! ! 5 - acid plutonic rocks |
| 94 | | ! ! 6 - basic plutonic rocks |
| 95 | | ! ! 7 - intermediat plutonic rocks |
| 96 | | ! ! 8 - pyroclastics |
| 97 | | ! ! 9 - carbonate sedimentary rocks |
| 98 | | ! ! 10 - mixed sedimentary rocks |
| 99 | | ! ! 11 - siliciclastic sedimentary rocks |
| 100 | | ! ! 12 - unconsolidated sediments |
| 101 | | ! ! 13 - acid volcanic rocks |
| 102 | | ! ! 14 - basic volcanic rocks |
| 103 | | ! ! 15 - intermediate volcanic rocks |

| 106 | | === 4.4 Soil shielding (Hartmann et al. (2014) === |
| 107 | | The factor corrects the weathering flux where the active zone in the soil is disconnected from the bedrock. |
