Wetlands of North African during mid-Holocene

We present high-resolution reconstructions of wetland distribution in the North Africa during the mid-Holocene (MH) using five calibrated wetland models and four precipitation levels. The five models are TCI1, TCI2, RFM1, RFM2 and LSM. The four precipitation levels are MH1, MH2, MH3 and MH4. The 20 simulations are in '.mat' format created by matlab.

In the updated Version 3 of this dataset, the simulations for the pre-industrial period (PI) with TCI and FRM models were added. For MH and PI conditions, we recommend to used the RFM2 simulations for realistic scenarios. For the present-day, the CW-TCI map of potential wetlands from Tootchi et al., 2019, ESSD should be used to be consistent with our result. For user's convenience, we have saved it in PI_simulations.mat as "Tootchi_PP" for present potential wetlands in North Africa.

本研究采用5套经过校准的湿地模型与4种降水情景，重建了全新世中期（mid-Holocene，简称MH）北非地区的湿地分布高分辨率结果。本次研究所用的5套模型分别为TCI1、TCI2、RFM1、RFM2与LSM，4种降水情景分别为MH1、MH2、MH3与MH4。全部20组模拟结果均以MATLAB生成的.mat格式存储。

在本数据集的更新版本3中，新增了基于TCI与FRM模型的前工业化时期（pre-industrial period，简称PI）模拟结果。针对全新世中期与前工业化时期的情景，我们推荐使用RFM2模型的模拟结果以获得更符合实际的模拟效果。对于现代情景，为保证结果一致性，建议采用Tootchi等人2019年发表于《地球系统科学数据》（Earth System Science Data, ESSD）的CW-TCI北非潜在湿地分布图。为方便使用者，我们已将该数据保存至PI_simulations.mat文件中，对应字段名为"Tootchi_PP"，即北非地区现代潜在湿地分布数据。

元数据：
空间分辨率为15角秒
空间范围为北纬0°至35°、西经20°至东经40°
数据包含4种取值：0代表非湿地，1与2代表湿地，15代表海洋。
