Global Summer Land Surface Temperature (LST) Grids, 2013

The Global Summer Land Surface Temperature (LST) Grids, 2013, represent daytime maximum temperature and nighttime minimum temperature in degree Celsius at a spatial resolution of 30 arc-seconds (~1km) during summer months of the northern and southern hemisphere for the year 2013. The grids are produced using Aqua Level-3 Moderate Resolution Imaging Spectroradiometer (MODIS) Version 5 global daytime and nighttime LST 8-day composite data (MYD11A2). For most regions, the LST grids provide the daytime maximum (1:30 p.m. overpass) and nighttime minimum (1:30 a.m. overpass) LST values for each grid cell from a 40-day time-span during July-August (Julian days 185-224) 2013 in the northern hemisphere and January-February (Julian days 001-040) 2013 in the southern hemisphere. LST grid cells with missing values resulting from high cloud cover in tropical regions were filled with daytime maximum and nighttime minimum LST values from April-May 2013 in the northern hemisphere and December 2013-January 2014 in the southern hemisphere, where available. Some data gaps remain in areas where data were insufficient (e.g., Central Africa).

全球夏季地表温度（LST）网格数据集，2013年版本，呈现了北半球和南半球夏季期间白天最高温度和夜间最低温度，单位为摄氏度，空间分辨率为30弧秒（约1公里）。该数据集基于Aqua卫星第三级中分辨率成像光谱仪（MODIS）版本5的全天候和夜间LST 8日合成数据（MYD11A2）生成。对于大多数地区，LST网格提供了从7月至8月（儒略日185-224）的40天时间跨度内，每个网格单元在下午1:30（过境时间）的白天最高温度和晚上1:30（过境时间）的夜间最低温度值。北半球为2013年4月至5月，南半球为2013年12月至2014年1月，在可用的情况下，对因热带地区高云覆盖导致的缺失值进行了填充，以白天最高温度和夜间最低温度值进行补充。在一些数据不足的地区（例如，中非），仍存在一些数据空白。
