The SatCO2 platform and data are free of charge. The goal is to promote the distribution and multidisciplinary application of marine remote sensing data.
The SatCO2 database collects satellite data and products from different agencies, produces datasets with algorithms developed by SOED, transforms and unifies data formats, and uploads SOED-processed data products for online analysis applications. The SatCO2 platform does not provide bulk download of original datasets. Acknowledgments and citations are required, including the SatCO2 platform, associated algorithmic signer, and original data provider, when results produced by users using the SatCO2 platform are published. For more detailed and updated information, please refer to:
