A seamless 1 km resolution global daytime (1:30 PM) land surface temperature dataset in 2024

This seamless LST dataset was generated from products of the National Aeronautics and Space Administration (NASA) Earth Observing System Terra and Aqua satellites (MOD11A1 and MYD11A1). The products are the Moderate-resolution Imaging Spectroradiometer (MODIS) 1 km resolution daily LST product Version 6.The original data include missing pixels due to factors such as cloud and shadow. We proposed a novel algorithm by using the spatiotemporal information of the original land surface temperature data to fill the missing pixels.

本无缝地表温度（Land Surface Temperature, LST）数据集源自美国国家航空航天局（National Aeronautics and Space Administration, NASA）地球观测系统（Earth Observing System）Terra与Aqua卫星的相关产品（MOD11A1、MYD11A1）。上述产品为中分辨率成像光谱仪（Moderate-resolution Imaging Spectroradiometer, MODIS）1公里分辨率每日地表温度产品第6版。原始数据存在因云、阴影等因素引发的像素缺失问题。本研究提出一种全新算法，利用原始地表温度数据的时空信息对缺失像素进行填补。
