WorldClim 2.1 Atmosphere Variables (1km): bimonthly solar radiation, wind speed, and vapor pressure - global and continental
收藏资源简介:
This dataset provides bimonthly composites of atmospheric variables from WorldClim 2.1 at 0.5 arc-minute (~1 km) spatial resolution, including solar radiation (srad), wind speed (wind), and water vapor pressure (vapr). Monthly WorldClim rasters were aggregated into bimonthly means to reduce redundancy and improve computational efficiency in ecological and environmental analyses.Available as global or continental layers. GeoTIFF (.tif) rasters contain six bimonthly layers. Variables included: srad: Mean solar radiation (kJ m⁻² day⁻¹) wind: Mean wind speed (m s⁻¹) vapr: Mean water vapor pressure (kPa) Data source: WorldClim v2.1 global climate database (Fick & Hijmans, 2017)Temporal aggregation: Bimonthly averages from monthly layers (Jan–Feb, Mar–Apr, …, Nov–Dec)Spatial resolution: 0.5 arc-minute (~1 km)Coordinate reference system: WGS84 (EPSG:4326) Citation:Fick, S.E. & Hijmans, R.J.

本数据集提供源自WorldClim 2.1的大气变量双月合成数据,空间分辨率为0.5弧分(约1公里),涵盖太阳辐射(solar radiation,缩写srad)、风速(wind speed,缩写wind)与水汽压(water vapor pressure,缩写vapr)。为降低数据冗余、提升生态与环境分析的计算效率,本数据集将原始月度WorldClim栅格数据聚合为双月平均值。该数据集可提供全球或大洲范围的图层。 数据采用GeoTIFF(.tif)栅格格式存储,每个文件包含6个双月图层。 包含的变量: srad:日均太阳辐射均值(kJ m⁻² day⁻¹) wind:平均风速(m s⁻¹) vapr:平均水汽压(kPa) 数据来源:WorldClim v2.1全球气候数据库(Fick & Hijmans,2017) 时间聚合方式:由月度图层聚合为双月平均值(1-2月、3-4月……11-12月) 空间分辨率:0.5弧分(约1公里) 坐标参考系统:WGS84(EPSG:4326) 引用格式:Fick, S.E. & Hijmans, R.J.
