Dynamic Masking for Chlorophyll-a Reconstruction in the Bohai and Yellow Sea: Dataset Generation and Trend Analysis

chlor_a_pred: Gap-free chlorophyll-a concentration dataset reconstructed using the method proposed in our paper, g/cm³. During the journal submission process, in response to the reviewers' requests, a series of adjustments were made to the model training/reconstruction process. The current version 2.0 corresponds to the dataset generated and analyzed using the method described in our paper (DOI: 10.1088/2515-7620/ae5766). Version 1.0 previously included "chlor_a": the chlorophyll-a concentration product derived from raw Himawari-8 satellite composites, and "chlor_a_filtered": a proxy target generated by applying bilateral filtering to "chlor_a". These have been removed from the current version and can be obtained from previous versions or through official Himawari-8 satellite channels.
