资源简介:

Overview: Daily maps for global daylight length, calculated for the year 2022. Processing steps: For each day within the year 2022, the photoperiod (sunshine hours on flat terrain) are calculated using the SOLPOS algorithm developed by the National Renewable Energy Laboratory (NREL), USA. Resultant values have been converted from hours to minutes. File naming scheme (DDD = day within year) (min is abbreviation for minute): daylight_min_2022_DDD.tif Projection + EPSG code: Latitude-Longitude/WGS84 (EPSG: 4326) Spatial extent: north: 90 south: -90 west: -180 east: 180 Spatial resolution: 30 arc seconds (approx. 1000 m) Temporal resolution: Daily Pixel values: unit: minutes Software used: GDAL 3.2.2 and GRASS GIS 8.2.0 Processed by: mundialis GmbH & Co. KG, Germany (https://www.mundialis.de/) Reference: National Renewable Energy Laboratory (NREL): SOLPOS 2.0 sun position algorithm (https://www.nrel.gov/grid/solar-resource/solpos.html)

概述: 本数据集包含2022年全球日照时长逐日地图集。 处理流程: 针对2022年的每一天,采用美国国家可再生能源实验室(National Renewable Energy Laboratory, NREL)开发的SOLPOS算法计算当日光周期(平坦地形下的日照小时数),并将计算结果从小时转换为分钟。 文件命名规则(DDD代表年内第几日,min为分钟的缩写):daylight_min_2022_DDD.tif 投影坐标系及EPSG代码:经纬度/WGS84(EPSG: 4326) 空间范围: 北:90° 南:-90° 西:-180° 东:180° 空间分辨率:30角秒(约1000米) 时间分辨率:逐日 像素值:单位为分钟 所用软件:GDAL 3.2.2与GRASS GIS 8.2.0 制作方:德国mundialis GmbH & Co.
