Land surface temperature (LST) is an important parameter that reflects the surface conditions and has significant implications for research in hydrology, ecology, environment, and biogeochemistry. Surface temperature is a sensitive indicator of climate change and an important prerequisite for mastering the laws of climate change. It is also a direct input parameter for many models and has wide applications in many fields, such as meteorology, climate, environmental ecology, hydrology, etc.\n
This data is sourced from NASA's official website, and the dataset contains MOD11A2 as the data product. Using MODIS surface temperature MOD11A2 data from 2000 to present as the data source, the data resolution is 1KM, the time resolution is 8 day, and the data format is hdf.
