摘      要：Land surface temperature(LST)is a key parameter in land surface *** National Aeronautics and Space Administration(NASA)recently released new Moderate Resolution Imaging Spectroradiometer(MODIS)LST products(MOD21 and MYD21).Here,we conducted a detailed comparison between the MYD11 and MYD21 LST data in China s *** LSTs of MYD21 were approximately 1℃ higher than those of MYD11 averaged for China s Mainland,as MYD21 corrected the cold bias of *** proportions of the valid value of MYD21 were generally lower than those of MYD11 because the cloud removal method of MYD21 was stricter than that of ***,the outliers were less significant in MYD11 than in MYD21 because the outliers in MYD11 were removed using temporal constraints on *** outliers in MYD21A2 resulted in a difference of greater than 3℃ in average seasonal surface urban heat island intensity(SUHII)between MYD11A2 and ***,using MYD11 may underestimate the slope of long-term trends of ***21 LST data may have some uncertainties in urban *** study provided a reference for users for selecting LST products and for data producers to further improve MODIS LST products.
