| | 76 | Two soil maps are available on the shared accounts and compatible with ORCHIDEE: |
| | 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 |
| | 79 | More details in http://forge.ipsl.jussieu.fr/orchidee/raw-attachment/wiki/Documentation/UserGuide/eqs_hydrol.pdf, section "6. Soil Texture". |

| | 82 | |
| | 83 | Several files exist with overlapping information: |
| | 84 | - irrigated_new.nc (0.5°) with: |
| | 85 | - the fraction of irrigated areas based on Siebert et al. (2005) initially available at 5 arc-min https://www.hydrol-earth-syst-sci.net/9/535/2005/hess-9-535-2005.html |
| | 86 | - wetland and floodplain fractions (no source provided) |
| | 87 | - irrigated_old.nc has teh same resolution as irrigated_new.nc and seems to also rely on Siebert et al. (2005)...? |
| | 88 | - floodplains.nc (0.5°) with: |
| | 89 | - the fraction of irrigated areas based on Siebert et al. (2005) initially available at 5 arc-min https://www.hydrol-earth-syst-sci.net/9/535/2005/hess-9-535-2005.html |
| | 90 | - the fractions covered by various wetlands and lakes according to GLWD database of Lehner and Doell (2004): floodplains (flood), lakes, reservoirs (dam), brackish/saline wetlands (saline), swamp and flood forests (swamp), intermittent wetlands, mostly found in arid areas (pond). The routing scheme defines the floodplains fraction as the sum of flood+dam+saline, while swamps and ponds undergo a special treatment (optional).
