Processed dataset for: Variability of chlorophyll-a concentration in Sangihe-Talaud Islands waters, North Sulawesi

This dataset contains the processed data used in the study entitled "Variability of chlorophyll-a concentration in Sangihe-Talaud Islands waters, North Sulawesi." The dataset includes monthly climatological chlorophyll-a concentration, sea surface temperature (SST), and wind speed derived from MODIS-Aqua Level-3 Standard Mapped Image products and ERA5 reanalysis data for the period 2003–2020. These processed data support the analyses and figures presented in the associated manuscript.
