资源简介:
Substrate temperature (deg C) at depths of 0, 2.5, 5, 10, 15, 20, 30, 50 and 100 cm under ground assuming a sand substrate and 50% shade from vegetation. Each netCDF file contains 24 layers of global extent, one for each hour of the day (starting at 0:00 hrs) for a given month of the year, at ~15km resolution.
Fileset Description:
The microclim dataset provides microclimate estimates of conditions above and below ground for each hour of the day for the middle day of each month based on a long-term average climatology. Details of this dataset are presented in [Kearney et al. 2014].
The dataset comprises a set of NetCDF files with one file per variable per month, each file comprising 24 layers (one for each hour of the day from 0:00 hrs to 23:00 hrs, so layer 13 is 12:00 midday) for the globe (852 rows, 2159 columns, latitudinal extents -58.57 to 83.43 degrees, longitudinal extents -180.00 to 180.00 degrees). For the naming convention, mon is month of the year (1 to 12, where 1 = Jan, 12 = Dec), shd is shade level in % (0, 25, 50, 75, 90, 100), and sub is substrate (soil, rock, sand).
To facilitate downloading the data, the NetCDF files are grouped into compressed (zipped) files, one per variable per shade and substrate type, each comprising all monthly values and, for the substrate temperatures, all depths. Note that not all variables are shade or substrate specific, specifically zenith angle, wind speeds, solar radiation, and 120 cm air temperature and relative humidity.
本数据集针对沙质基质且植被遮挡50%光照的场景,提供地下0、2.5、5、10、15、20、30、50及100厘米深度处的基质温度(摄氏度)数据。每个netCDF(网络通用数据格式)文件包含全球范围的24层数据,对应某一年份指定月份的每日每一小时(从0:00起),空间分辨率约为15千米。
文件集说明:
microclim数据集基于长期平均气候学数据,提供每月中旬每日每小时的地上及地下微气候状况估算结果。该数据集的详细信息参见[Kearney等人,2014]。
该数据集由一系列netCDF文件组成,每月对应每个变量各一个文件;每个文件包含全球范围的24层数据(对应每日0:00至23:00的每一小时,因此第13层对应正午12:00),数据维度为852行、2159列,纬度范围为-58.57°至83.43°,经度范围为-180.00°至180.00°。
文件命名规则如下:mon代表年度月份(取值1至12,其中1对应1月,12对应12月);shd代表光照遮挡百分比(取值0、25、50、75、90、100);sub代表基质类型(soil、rock、sand分别对应土壤、岩石、沙质基质)。
为便于数据下载,netCDF文件按变量、遮挡类型及基质类型分组打包为压缩(ZIP)文件,每组包含对应所有月份的数据;对于基质温度数据集,还包含所有深度层级的数据。需注意,并非所有变量都与遮挡程度或基质类型相关,具体包括天顶角、风速、太阳辐射,以及120厘米高度的气温和相对湿度。
