The 3MI polarimeter provides multi-spectral, multi-polarization imaging for global climate monitoring and atmospheric research. Featuring an extended spectral range and enhanced spatial resolution, it achieves superior performance over previous climate sensors. Rigorous polarization sensitivity analysis ensures that the instrument meets strict accuracy requirements for long-term observational consistency.
