Based on long-term remote sensing products, this paper constructs evaluation indicators for surface high temperatures and analyzes the distribution characteristics of surface high temperatures in Hunan Province over the past 20 years, aiming to provide technical references for agricultural production, disaster prevention and mitigation. Firstly, the daily surface high temperature dataset are calculated using long-term data regression of MYD11A1, MYD13A1 and MYD09GA from 2002 to 2021. The percentage method, percentile method and trend ratio method are used to construct remote sensing evaluation indicators for surface high temperatures, then the spatial and temporal distribution characteristic. . .
