Overview

New MAIAC algorithm retrieves aerosol optical depth and layer height in various conditions, highlighting accuracy improvements.

Key Points

  • The MAIAC algorithm simultaneously retrieves aerosol optical depth and layer height, enhancing data sensitivity.
  • A validation study shows global AOD accuracy with correlation coefficient R ∼ 0.71-0.73 and RMSE ∼ 0.4.
  • The aerosol layer height retrieval demonstrates global RMSE ∼ 1.1 km, with a significant percentage within expected error margins.
  • This version 3 MAIAC EPIC algorithm supports Earth system modeling and air quality applications over the 2015–2025 period.
