Scripts and datas for "Climate-driven projections of future global wetlands extent"

Computations scripts (1, 2), associated input dataset (3), and output datasets for wetland fractions (4, 5) used and presented in the study:

L. Hardouin, B. Decharme, J. Colin, C. Delire: Climate-driven projections of future global wetlands extent.

The calculation and input scripts include:1_var_comput : Calculation of the main variables used to diagnose wetlands: depth of the "active" layer d_wtl, liquid water content w_l, ice content and maximum content in the layer d_wtl.

2_TOPMODEL : The scripts used to diagnose the wetland fraction and to calibrate the models using the TOPMODEL approach. In this folder, the mean, maximum, minimum, standard deviation and skewness datasets of the topographic indices at the grid-cell level are also included.

3_alpha_and_beta : Calibrated alpha and beta parameters used to obtain the historical and projected wetland fractions with the calibrated version.

The outputs datasets contain:

4_fwtl_model_period : The fraction of wetlands computed from each model in the calibrated version, for the historical period and the 4 SSPs scenarios presented in the submitted work.

5_not_calibrated_fwtl_model_period : The fraction of wetlands computed from each model in the uncalibrated version with alpha=0.65, for the historical period and the 4 SSPs scenarios, where only the historical period is used in the submitted work.

Additional data not created by the authors are needed to reproduce the study (see the Open research section in the submitted article). Feel free to contact the authors ([e-mail]) for any help or questions.
