MODIS LST monthly daytime and nighttime low (0.05), median (0.50) and high (0.95) temperatures for year 2011 at 1-km
收藏资源简介:
Layers include: Land Surface Temperature daytime low (0.05), median (0.50) and high (0.95) temperatures for the year 2011. Derived using the data.table package and quantile function in R. For more info about the MODIS LST product see: https://lpdaac.usgs.gov/dataset_discovery/modis/modis_products_table/mod11a2_v006. Antarctica is not included.

File naming convention: clm = theme: climate, lst = variable: land surface temperature, mod11a2.daytime = determination method: MOD11A2 product, day time values, d = median value / sd = standard deviation / u.95 = aggregation/statistics method: 95% probability upper quantile, 1km = spatial resolution / block support: 1 km, s0..0cm = vertical reference: land surface, 2000..2020 = time reference: from 2000 to 2020, v1.1 = version number: 1.1,
本数据集包含以下图层:2011年日间地表温度(Land Surface Temperature, LST)的0.05分位数(低温阈值)、0.50分位数(中位温度)以及0.95分位数(高温阈值)。该数据集通过R语言的data.table包与quantile函数计算得到。有关MODIS LST产品的更多详细信息,请参阅:https://lpdaac.usgs.gov/dataset_discovery/modis/modis_products_table/mod11a2_v006。本数据集未包含南极洲区域。 若需访问并可视化地图,请使用OpenLandMap.org平台。若需使用云优化GeoTIFF(Cloud-Optimized-GeoTIFF, COG)下载并处理地图数据,请参阅<strong>本教程</strong>。 若您发现OpenLandMap地图存在漏洞、伪影或不一致之处,或有相关疑问,请通过以下渠道反馈: 代码相关技术问题与咨询:https://gitlab.com/openlandmap/global-layers/-/issues 一般性疑问与意见反馈:https://disqus.com/home/forums/landgis/ 所有内部文件均采用GDAL(地理空间数据抽象库)的"COMPRESS=DEFLATE"创建选项进行压缩。 文件命名规则说明如下: clm = 主题(theme):气候(climate); lst = 变量(variable):地表温度(Land Surface Temperature, LST); mod11a2.daytime = 确定方法:MOD11A2产品日间值; d = 中位值(median value)/ sd = 标准差(standard deviation)/ u.95 = 聚合/统计方法:95%概率上分位数; 1km = 空间分辨率/区块支撑范围:1 km; s0..0cm = 垂直参考基准:地表; 2000..2020 = 时间参考范围:2000年至2020年; v1.1 = 版本号:1.1。
