Executive editor
This study presents a comprehensive and quantitative evaluation of the global radiometric uncertainty budget for the IASI satellite instruments, which are key components of long-term atmospheric monitoring. The work represents a timely and significant advance in ensuring the traceability and stability of satellite-based climate observations.
Short summary
This study establishes the global radiometric uncertainty budget of the Infrared Atmospheric Sounder Interferometer (IASI) instruments onboard Eumetsat first generation MetOp satellites. Major contributions to the budget arise from the correction of the analog non-linearity, the black body characterization, the scan mirror reflectivity and the background radiance instability. The estimated uncertainty remains relatively stable throughout the lifetime of the instruments.
