GlobalHighPM2.5 (2022)

Here is the first big data-derived gapless (spatial coverage = 100%) daily, monthy, and annual 1 km (i.e., D1K, M1K, and Y1K) global PM2.5 dataset over land for the year 2022. This dataset yields a high quality with a cross-validation coefficient of determination (CV-R2) of 0.91 and an root-mean-square error (RMSE) of 9.20 µg m-3 on the daily basis.
