LTSER Zone Atelier Brest Iroise - Regional climate model data from EURO-CORDEX for the eLTER project

The dataset provides climate scenario data as time series based on an ensemble of EURO-CORDEX regional climate model (RCM) simulations for each LTER site location throughout Europe. The EURO-CORDEX ensemble used here consists of dynamically downscaled CMIP5 global climate models (GCMs) for different greenhouse gas concentration trajectories, the representative concentration pathways (RCPs: RCP2.6 (6), RCP4.5 (14) and RCP8.5 (14)). The datasets cover the following, non-bias adjusted variables: tas = near-surface air temperature [degC], tasmin = daily minimum near-surface air temperature [degC], tasmax = daily minimum near-surface air temperature [degC], pr = precipitation sum [mm day-1], psl = mean sea level pressure [Pa], huss = near-surface specific humidity [kg kg-1], rsds = surface downwelling shortwave radiation [W m-2], and sfcWind = near-surface wind speed [m s-1] in txt and netCDF data format at daily, monthly and yearly temporal resolution. Each ZIP-file data package contains the data file as well as an extensive disclaimer with additional information.

本数据集提供基于欧洲各长期生态研究（Long Term Ecological Research, LTER）站点位置的欧洲协调区域气候降尺度试验（EURO-CORDEX）区域气候模式（Regional Climate Model, RCM）集合模拟结果的时间序列气候情景数据。本次采用的EURO-CORDEX集合模拟集，由针对不同温室气体浓度轨迹的动态降尺度耦合模式比较计划第五阶段（Coupled Model Intercomparison Project Phase 5, CMIP5）全球气候模式（Global Climate Model, GCM）结果组成，对应典型浓度路径（Representative Concentration Pathways, RCPs）：RCP2.6(6)、RCP4.5(14)与RCP8.5(14)。数据集涵盖以下未经过偏差校正的变量：tas为近地表气温（单位：摄氏度，[degC]）、tasmin为日最低近地表气温（单位：摄氏度，[degC]）、tasmax为日最低近地表气温（单位：摄氏度，[degC]）、pr为降水总量（单位：毫米/日，[mm day⁻¹]）、psl为平均海平面气压（单位：帕斯卡，[Pa]）、huss为近地表比湿（单位：千克/千克，[kg kg⁻¹]）、rsds为地表向下短波辐射（单位：瓦/平方米，[W m⁻²]），以及sfcWind为近地表风速（单位：米/秒，[m s⁻¹]）；数据以纯文本（txt）与网络通用数据格式（netCDF）存储，时间分辨率涵盖日度、月度与年度三个维度。每个ZIP压缩文件数据包均包含数据文件与一份包含补充信息的详尽免责声明。
