ChinaHighTEMavg: Daily Seamless 1 km Average Air Temperature Dataset for China (2003–Present)
ChinaHighTEM is part of a series of long-term, seamless, high-resolution, and high-quality datasets of air pollutants for China (i.e., ChinaHighAirPollutants, CHAP). It is generated from big data sources (e.g., ground-based measurements, satellite remote sensing products, atmospheric reanalysis,
ChinaHighTEM is part of a series of long-term, seamless, high-resolution, and high-quality datasets of air pollutants for China (i.e., ChinaHighAirPollutants, CHAP). It is generated from big data sources (e.g., ground-based measurements, satellite remote sensing products, atmospheric reanalysis, and model simulations) using artificial intelligence, taking into account the spatiotemporal heterogeneity of air pollution.
Here is the big data-derived seamless (spatial coverage = 100%) daily 1 km (i.e., D1K) average air temperature (TEMavg) dataset for China from 2003 to the present. This dataset exhibits high quality, with a cross-validation coefficient of determination (CV-R2) of 0.99 and a root-mean-square error (RMSE) of 1.18 ℃ on a daily basis.
