ESA CCI MRLC dataset conversion to ORCHIDEE PFTs
1. GENERIC PFTs distributed by K.Harper (UCL)
2. Köppen-Geiger climate classification
- The data are taken from http://koeppen-geiger.vu-wien.ac.at/present.htm
- The original grid of 1/36=0.0277° is resampled to 0.25° by calculating the class fractions
- Classes are joined into 7 groups following the table shown below
- Points without data are filled by the dominant class of each latitude

3. C.Still C3/C4 vegetation type partitioning (for grasses)
- The data are provided by C.Still at 1/6=0.166° for 3 classes:
- C3 herbaceous cover
- C4 herbaceous cover
- C3 tree cover
where C3_herbaceous_cover + C4_herbaceous_cover + C3_tree_cover = 1
- C4 fraction is calculated as C4_herbaceous_cover / (C3_herbaceous_cover + C4_herbaceous_cover)
- The pixels with no C3/C4 data are considered to be pure C3
- The maps are resampled to 0.25° by calculating the class fractions
4. LUH C3/C4 vegetation type partitioning (for crops)
- The data are provided within TRENDY2020 (land use harmonization data) at 0.25° for 12 classes:
- primf (forested primary land)
- primn (non-forested primary land)
- secdf (potentially forested secondary land)
- secdn (potentially non-forested secondary land)
- urban (urban land)
- c3ann (C3 annual crops)
- c4ann (C4 annual crops)
- c3per (C3 perennial crops)
- c4per (C4 perennial crops)
- c3nfx (C3 nitrogen-fixing crops)
- pastr (managed pasture)
- range (rangeland)
- C4 fraction is calculated as (c4ann + c4per) / (c3ann + c4ann + c3per + c4per + c3nfx)
- The pixels with no data are considered to be pure C3
- The LUH data are provided and used on the yearly basis
5. ESA CCI water bodies product
- The water bodies product is distributed as a static map at 150 m spatial resolution
- It has the distinction between ocean and inland water (legend: 0-Ocean, 1-Land, 2-Inland Water)
- The data are resampled to 0.25° by calculating the class fractions
- The ocean mask is defined where OCEAN > 0.999, it is used as the land-sea mask of the final map
- The coast mask is defined where 0 < OCEAN < 0.999, the ocean water content at this area is excluded from the balance, the inland water content is assigned to bare soil
- The land mask is defined where OCEAN = 0, the inland water content at this area is assigned to bare soil (following the cross-walking table below)
6. ORCHIDEE PFT maps production
- The ORCHIDEE PFT maps are produced by combining all the products shown above using the cross-walking table (see below, in brackets: total area in Mkm2)
- The resulting fractions below 0.001 are set to zero
- The final fractions are normalized to have the sum across PFTs equal to one
- The data are masked where OCEAN=1 or sum(GENERIC)=0
