I)SUMMARY This repository contains a harmonized database for the study of terrestrial ecosystem changes published in [Bueso et al., 2021]. It covers the period June 2010 - July 2020 and includes the following variables, which were harmonized to a common spatial scale of 25km and monthly temporal resolution and clustered as detailed in [Bueso et al., 2021]: - SM: soil moisture from SMOS-IC v2<br> - VOD: vegetation optical depth from SMOS-IC v2<br> - NDVI: Normalized Vegetation Difference Index from MODIS, product MOD13Q1 v6<br> - PREC: Rainfall from PERSIANN-CDR v2.2. Additionally, land cover information from MODIS MCD12Q1 collection 6 for years 2011 and 2019 is provided for each cluster. II) CONTACT For questions, please e-mail Diego Bueso at diego.bueso@uv.es III) DATABASE We provide the maps of identified clusters by quantile of SM and VOD and the code to generate Figs 1 and 2 of supplementary material in [Bueso et al., 2023]. We then provide for each identified cluster .mat files containing the variables described above. Further details are in the readme.txt file IV) CITE To properly acknowledge the dataset we kindly encourage users to (1) cite the DOI as an in-text citation and/or in the data acknowledgements in any publication and (2) reference the following publication: D. Bueso, M. Piles, P. Ciais, J-P. Wigneron, Á. Moreno-Martínez, G. Camps-Valls, "Soil and vegetation water content identify the main terrestrial ecosystem changes", National Science Review, 2023, https://doi.org/10.1093/nsr/nwad026

一、概述 本仓库包含用于陆地生态系统变化研究的统一协调数据库,该数据集相关成果发表于[Bueso等人,2021]。数据集覆盖2010年6月至2020年7月时段,包含以下经过统一校准的变量:所有变量均被统一至25km的空间尺度与月度时间分辨率,并按照[Bueso等人,2021]中的详细方法进行聚类: - SM:土壤湿度(Soil Moisture),源自SMOS-IC v2产品 - VOD:植被光学厚度(Vegetation Optical Depth),源自SMOS-IC v2产品 - NDVI:归一化差分植被指数(Normalized Difference Vegetation Index),源自MODIS产品MOD13Q1 v6 - PREC:降雨量,源自PERSIANN-CDR v2.2产品 此外,本数据集还为每个聚类提供了2011年与2019年的MODIS MCD12Q1 第六版集合的土地覆盖信息。 二、联系方式 如有疑问,请发送邮件至Diego Bueso,邮箱地址:diego.bueso@uv.es 三、数据集详情 我们提供了基于土壤湿度与植被光学厚度分位数划分得到的聚类结果地图,以及复现[Bueso等人,2023]中补充材料图1和图2的代码。此外,我们为每个已识别的聚类提供了包含上述所有变量的.mat格式文件。更多详细信息请参阅readme.txt文件。 四、引用说明 为合理认可本数据集的贡献,我们恳请用户:(1)在任何出版物中以文内引用或数据致谢的方式标注该数据集的DOI;(2)引用以下发表文献: D.
