Input data set: Historical land transformation

Protocol relation: Protocol
Data Type: Direct human forcings
Simulation rounds: ISIMIP3a

Gridded historical annual land transformation for the time periods 1850-2021 on a 0.5° grid based on the LUH2 v2.1f data set..

Scenarios: 1901soc, 2015soc, histsoc
Variables: land-transformation

Land transformation data based on the HYDE 3.2 data set (Klein Goldewijk, 2016), but harmonized by Hurtt et al. (LUH2 v2.1f data set; see: Hurtt, Chini, Sahajpal, Frolking, & et al, 2020; Interpolated to the ISIMIP 0.5° grid using first-order conservative remapping. The data have been extended up to 2021 by copying the 2017 data into the following years.

The data set consists of 115 land transformation categories:
c3ann_to_secdf, c3ann_to_secdn, c3ann_to_urban, c3ann_to_c4ann, c3ann_to_c3per, c3ann_to_c4per, c3ann_to_c3nfx, c3ann_to_pastr, c3ann_to_range, c3nfx_to_secdf, c3nfx_to_secdn, c3nfx_to_urban, c3nfx_to_c3ann, c3nfx_to_c4ann, c3nfx_to_c3per, c3nfx_to_c4per, c3nfx_to_pastr, c3nfx_to_range, c3per_to_secdf, c3per_to_secdn, c3per_to_urban, c3per_to_c3ann, c3per_to_c4ann, c3per_to_c4per, c3per_to_c3nfx, c3per_to_pastr, c3per_to_range, c4ann_to_secdf, c4ann_to_secdn, c4ann_to_urban, c4ann_to_c3ann, c4ann_to_c3per, c4ann_to_c4per, c4ann_to_c3nfx, c4ann_to_pastr, c4ann_to_range, c4per_to_secdf, c4per_to_secdn, c4per_to_urban, c4per_to_c3ann, c4per_to_c4ann, c4per_to_c3per, c4per_to_c3nfx, c4per_to_pastr, c4per_to_range, pastr_to_c3ann, pastr_to_c3nfx, pastr_to_c3per, pastr_to_c4ann, pastr_to_c4per, pastr_to_range, pastr_to_secdf, pastr_to_secdn, pastr_to_urban, primf_to_c3ann, primf_to_c3nfx, primf_to_c3per, primf_to_c4ann, primf_to_c4per, primf_to_pastr, primf_to_range, primf_to_secdn, primf_to_urban, primn_to_c3ann, primn_to_c3nfx, primn_to_c3per, primn_to_c4ann, primn_to_c4per, primn_to_pastr, primn_to_range, primn_to_secdf, primn_to_urban, range_to_c3ann, range_to_c3nfx, range_to_c3per, range_to_c4ann, range_to_c4per, range_to_pastr, range_to_secdf, range_to_secdn, range_to_urban, secdf_to_c3ann, secdf_to_c3nfx, secdf_to_c3per, secdf_to_c4ann, secdf_to_c4per, secdf_to_pastr, secdf_to_range, secdf_to_secdn, secdf_to_urban, secdn_to_c3ann, secdn_to_c3nfx, secdn_to_c3per, secdn_to_c4ann, secdn_to_c4per, secdn_to_pastr, secdn_to_range, secdn_to_secdf, secdn_to_urban, urban_to_secdf, urban_to_secdn, urban_to_c3ann, urban_to_c4ann, urban_to_c3per, urban_to_c4per, urban_to_c3nfx, urban_to_pastr, urban_to_range.
