Atmospheric methane retrieval and validation using FY-3F/ HIRAS-II observations

Key Points

• The validation process confirms accurate methane retrieval from remote sensing data, enhancing atmospheric assessments.
• Key evidence shows strong correlation in methane concentrations between FY-3F data and local measurements at three distinct sites.
• Observational analysis employs FY-3F/HIRAS-II to compare and validate methane retrieval methods over various atmospheric conditions.
• This study highlights the potential for improved environmental monitoring by using remote sensing data for methane tracking.
