Alptal - 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.

本数据集提供覆盖欧洲全境所有长期生态研究（Long Term Ecological Research, LTER）站点位置的气候情景时序数据，其数据基础为EURO-CORDEX区域气候模式（Regional Climate Model, RCM）的集合模拟结果。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、经动力降尺度的第五次耦合模式比较计划（Coupled Model Intercomparison Project Phase 5, CMIP5）全球气候模式（Global Climate Model, GCM）结果构成，涉及的典型浓度路径（Representative Concentration Pathways, RCPs）包括RCP2.6（6组）、RCP4.5（14组）与RCP8.5（14组）。数据集涵盖以下未经过偏差校正的变量：近地表气温（tas）[单位：摄氏度，degC]、日最低近地表气温（tasmin）[单位：摄氏度，degC]、日最低近地表气温（tasmax）[单位：摄氏度，degC]、降水总量（pr）[单位：毫米·日⁻¹，mm day⁻¹]、海平面气压（psl）[单位：帕斯卡，Pa]、近地表比湿（huss）[单位：千克·千克⁻¹，kg kg⁻¹]、地表向下短波辐射（rsds）[单位：瓦·米⁻²，W m⁻²]，以及近地表风速（sfcWind）[单位：米·秒⁻¹，m s⁻¹]。上述数据以txt与网络通用数据格式（netCDF）存储，时间分辨率涵盖日尺度、月尺度与年尺度。每个ZIP压缩数据包均包含数据文件与一份详尽的免责声明及补充信息。
