Multi-temporal Monthly 5.5-km LST data, latitude, longitude, and DEM data

LST monthly data for SW USA. Around local solar time 01:30 (night), and 13:30 (day) LST data are acquired from the MODIS instrument on board the Aqua polar orbiting satellite. The LST accuracy is better than 1K (0.5 K in most cases) under real clear-sky conditions. Data from real clear-sky conditions within a calendar month are averaged to yield the MYD11C2 product. The data set provide a continuous (monthly averaged LST) sampling of the earth’s surface with a spatial resolution of 3 minutes (0.05 degrees, corresponding to 5.6 km approximately at the equator) referenced to a geographic latitude/longitude grid, with WGS 84 being the horizontal datum.

美国西南部的月度地表温度（Land Surface Temperature, LST）数据集。该数据集的地表温度数据由搭载于极轨卫星Aqua上的中分辨率成像光谱仪（Moderate-resolution Imaging Spectroradiometer, MODIS）获取，对应当地太阳时01:30（夜间）与13:30（日间）两个观测时刻。在纯晴空条件下，地表温度反演精度优于1开尔文，多数场景下可控制在0.5开尔文以内。将单个日历月内所有纯晴空条件下的观测数据进行平均处理，即可得到MYD11C2产品。本数据集以世界大地测量系统1984（World Geodetic System 1984, WGS 84）为水平基准面，基于地理经纬度网格构建，可对地球表面进行连续的月度平均地表温度采样，空间分辨率为3弧分（0.05度，在赤道处约对应5.6千米）。
