MOD11A2 1KM地表温度/反射率8天合成产品

"MODIS Terra星1KM地表温度/发射率8天合成L3产品（MOD11A2）是由每日1KM地表温度/发射率产品（MOD11A1）合成的，存储的是8天中晴好天气下的地表温度/发射率的平均值，投影为正弦曲线投影。
MOD11A2有白天和夜间数据、质量评估、观测时间、观测角、晴好白天和夜晚的天数以及不同地表覆盖类型在波段31-32的地表发射估计。"

The MODIS Terra satellite 1-kilometer 8-day composite Level 3 (L3) Land Surface Temperature/Emissivity product (MOD11A2) is synthesized from the daily 1-kilometer Land Surface Temperature/Emissivity product (MOD11A1). It stores the average values of land surface temperature and emissivity under clear-sky conditions over an 8-day period, with a sinusoidal projection. MOD11A2 includes daytime and nighttime datasets, quality assessment information, observation times, viewing angles, the number of clear-sky daytime and nighttime observation days, as well as land surface emissivity estimates for different land cover types in bands 31 and 32.
