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全境各长期生态研究（Long Term Ecological Research，LTER）站点位置的欧洲区域气候降尺度试验（EURO-CORDEX）集合区域气候模式（Regional Climate Model，RCM）模拟结果的时间序列气候情景数据。本次采用的EURO-CORDEX集合方案，由针对不同温室气体浓度情景的、经动力降尺度的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）结果构成，对应典型浓度路径（Representative Concentration Pathways，RCPs）：RCP2.6（6种情景）、RCP4.5（14种情景）与RCP8.5（14种情景）。本数据集包含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⁻¹（mm day⁻¹）]，psl为海平面平均气压[单位：帕斯卡（Pa）]，huss为近地表比湿[单位：千克·千克⁻¹（kg kg⁻¹）]，rsds为地表向下短波辐射[单位：瓦·米⁻²（W m⁻²）]，sfcWind为近地表风速[单位：米·秒⁻¹（m s⁻¹）]。数据以txt和网络通用数据格式（Network Common Data Form，netCDF）存储，时间分辨率涵盖日、月、年三个尺度。每个ZIP格式的数据压缩包均包含数据文件与一份详尽的免责声明及附加信息。
