However, factors like cloud contamination have led to invalid values in the LST product, which has restricted the application of the LST dataset. Therefore, the reconstruction of LST products is challenging, and it is attracting widespread attention. This study compared the performance of different algorithms (XGBoost, GBDT, RF, POLY, MLR) and different training sets (using only good-quality pixels or using both good-quality and other-quality pixels) in the estimation of missing pixels in the LST data, obtaining a seamless daily 1 km LST dataset of MODIS Terra-day, Aqua-day, Terra-night, and Aqua-night data for Zhejiang Province and its surrounding areas from 2000 to 2022. The results demonstrated that the performance of machine-learning models is significantly better than that of linear models, and among the five models, XGBoost performed the best, with an RMSE of less than 1 \u00b0C. The Wilcoxon test between the reconstructed LST and the true LST values revealed that including both good-quality and other-quality pixels for reconstruction resulted in a 33% increase in the number of days with non-significant differences compared with using only good-quality pixels. Moreover, the reconstructed nighttime LST has a lower RMSE compared with the reconstructed daytime LST, and the RMSE of the reconstructed LST on the Terra satellite is lower than the RMSE of the reconstructed LST on the Aqua satellite. The RMSEs for the reconstructed LSTs are 0.50 \u00b0C, 0.61 \u00b0C, 0.36 \u00b0C, and 0.39 \u00b0C, corresponding to Terra-day, Aqua-day, Terra-night, and Aqua-night for images with coverage reaching 70%, 0.65 \u00b0C, 0.83 \u00b0C, 0.49 \u00b0C, respectively, and 0.52 \u00b0C for images with coverage less than 70%. The accuracy of the reconstructed LSTs using our proposed framework outperforms the existing reconstruction methods. The 1 km daily seamless LST products can be applied in various fields, such as air temperature estimation, climate change, urban heat island, and crop temperature stress monitoring.<\/jats:p>","DOI":"10.3390\/rs15204982","type":"journal-article","created":{"date-parts":[[2023,10,17]],"date-time":"2023-10-17T08:10:19Z","timestamp":1697530219000},"page":"4982","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A New Framework for the Reconstruction of Daily 1 km Land Surface Temperatures from 2000 to 2022"],"prefix":"10.3390","volume":"15","author":[{"given":"Yuanjun","family":"Xiao","sequence":"first","affiliation":[{"name":"Institute of Applied Remote Sensing and Information Technology, Zhejiang University, Hangzhou 310058, China"},{"name":"Key Laboratory of Agricultural Remote Sensing and Information Systems, Hangzhou 310058, China"}]},{"given":"Shengcheng","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Applied Remote Sensing and Information Technology, Zhejiang University, Hangzhou 310058, China"},{"name":"Key Laboratory of Agricultural Remote Sensing and Information Systems, Hangzhou 310058, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4627-6021","authenticated-orcid":false,"given":"Jingfeng","family":"Huang","sequence":"additional","affiliation":[{"name":"Institute of Applied Remote Sensing and Information Technology, Zhejiang University, Hangzhou 310058, China"},{"name":"Key Laboratory of Agricultural Remote Sensing and Information Systems, Hangzhou 310058, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0226-8492","authenticated-orcid":false,"given":"Ran","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Automation, Hangzhou Dianzi University, Xiasha Higher Education Zone, Hangzhou 310018, China"}]},{"given":"Chang","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Applied Remote Sensing and Information Technology, Zhejiang University, Hangzhou 310058, China"},{"name":"Key Laboratory of Agricultural Remote Sensing and Information Systems, Hangzhou 310058, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"344","DOI":"10.1016\/S0034-4257(01)00284-X","article-title":"Forward and Inverse Modeling of Land Surface Energy Balance Using Surface Temperature Measurements","volume":"79","author":"Friedl","year":"2002","journal-title":"Remote Sens.
