Input data set: Historical land transformation

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

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; https://luh.umd.edu). 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.
