1km surface ozone data set in China, 2018-2020

1. Time coverage: 2018-2020; Space coverage: China (excluding the South China Sea); Time resolution: days; Spatial resolution: 1 km; 2. The first step is to predict the 1-kilometer full-coverage MDA 8 concentration data based on the RF model, the second step is to carry out Kriging interpolation based on the residuals of the real site data and the predicted data, and the third step is to overlay the first two steps to obtain the high-precision spatial-temporal resolution MDA 8 dataset in China (CHROD: China High-Resolution O3 Dataset); 3. The kriging interpolation is not used in 0181222-20181226 and 20190824 (due to the lack of station MDA 8 concentration data in the sample data), and the results of RF model simulation are used to replace the final MDA 8 concentration.；4. The data format of CHROD is TIFF, and the NC format will be uploaded later, and the relevant NC to TIFF scripts will also be uploaded (including MATLAB and Python)
