Description

ESA CCI Land Cover dataset (https://www.esa-landcover-cci.org/) is used to produce PFT maps for the ORCHIDEE model.

Transformation of initial data is done in the following steps:

Aggregation ESA CCI LC (300 m) → Generic PFTs (given resolution), using:

aggregation tool "lc-user-tools" (v4.3, release 03/12/2018)
yearly ESA CCI land cover map v2.0.7b (1992-2015) or v2.1.1 (2016-2019) at 300 m resolution with 38 land cover classes
static Köppen-Geiger climate zone map at 300 m resolution grouped into 5 climate zones
- original data: 10.5194/hess-11-1633-2007 , source: link
- method of grouping climate zones: 10.5194/gmd-4-993-2011
- final Köppen-Geiger map with 5 zones used in aggregation: tif
cross-walking table (v2.4) matching ESA CCI classes with generic PFTs: csv
additional cross-walking table (v2.4) refining the conversion of several ESA CCI classes depending on climate zone: csv

Aggregation Generic PFTs (given resolution) → ORCHIDEE PFTs (given resolution), using:

python script "gen2orc.py": link (github) or link (SVN)
yearly Generic PFT maps (1992-2019)
static Köppen-Geiger climate zone map (Rubel et al., 2017) for splitting trees
static C3/C4-partitioning map (C. Still et al., 2018) for splitting grasses
yearly land-use maps (LUH2-GCB2022) for splitting crops
static water bodies map (ESA CCI WB v4.0) for splitting inland/coastal waters and defining land-sea mask

The data are available on obelix:

Data aggregated into 15 generic PFTs at 8 different resolutions (1°, 0.5°, 0.25°, 0.125°, 0.1°, 0.05°, 0.025°, 0.0125°) on yearly basis (1992-2019):
