MYDDIS Aqua星MYD11A2 1KM 地表温度/发射率8天合成产品

"MODIS Aqua星1KM地表温度/发射率8天合成L3产品（MYD11A2）是由每日1KM地表温度/发射率产品（MYD11A1）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。 MYD11A2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 8-day composite Level 3 product (MYD11A2) of 1-kilometer Land Surface Temperature and Emissivity from the MODIS Aqua satellite is generated by compositing the daily 1-kilometer Land Surface Temperature and Emissivity product (MYD11A1). It stores the average values of Land Surface Temperature and Emissivity from clear-sky observations over an 8-day period, and is projected using the Sinusoidal projection. MYD11A2 includes daytime and nighttime datasets, quality assessment information, observation times, observation angles, the number of valid clear-sky daytime and nighttime observation days, as well as surface emissivity estimates for different land cover types in bands 31 and 32.
