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.
