MODIS/Aqua Land Surface Temperature/Emissivity 5-Min L2 Swath 1km NRT

The MODIS/Aqua Land Surface Temperature/Emissivity 5-Min L2 Swath 1km Near Real Time (NRT), short name MYD11_L2, incorporate 1 km pixels, which are produced daily at 5-minute increments using the generalized split-window algorithm. This algorithm is optimally used to separate ranges of atmospheric column water vapor and lower boundary air surface temperatures into tractable sub-ranges. The surface emissivities in bands 31 and 32 are estimated from land cover types. The data inputs include the MODIS L1B calibrated and geolocated radiances, geolocation, cloud mask, atmospheric profiles, land and snow cover. The MYD11_L2 data set comprises swath data obtained in 5-minute sensor collection periods, and includes the following Science Data Set (SDS) layers:- LST- Quality control assessment- Error estimates- Bands 31 and 32 emissivities- Zenith angle of the pixel view- Observation time- Geographic coordinates for every five scan lines and samples.Produced daily, MYD11_L2 is an unprojected level-2 product, which provides the input for the level-3 products.

MODIS/Aqua陆地表面温度/发射率5分钟L2扫描带1公里近实时（NRT）数据集，简称MYD11_L2，融合了1公里像素，这些像素以每日5分钟的增量使用广义分窗算法生成。该算法被优化用于将大气柱水汽和下边界空气表面温度的范围划分为可处理的子范围。波段31和32的表面发射率是根据土地覆盖类型估算的。数据输入包括MODIS L1B校准和地理定位辐射亮度、地理定位、云掩膜、大气剖面、陆地和积雪覆盖。MYD11_L2数据集包含在5分钟传感器采集期间获取的扫描带数据，并包括以下科学数据集（SDS）层：地表温度质量控制评估、误差估计、波段31和32发射率、像素视场天顶角、观测时间以及每五条扫描线和样本的地理坐标。每日生成的MYD11_L2是一种未投影的二级产品，为三级产品提供输入。
