The 14th Asian Aerosol Conference (AAC) 2025 is taking place this week in Mumbai, India, bringing together the international community to discuss the role of aerosols in air quality and climate action. GRASP Earth is participating in the event to address the requirement for accurate remote-sensing inversion algorithms. As satellite missions progress, ground-based measurements remain necessary for characterizing aerosol types in climate and air-quality research.

Richard Kleidman, GRASP Earth fellow and AirPhoton CMO, has presented the following studies utilizing the GRASP algorithm during the conference:

  • Optical and microphysical properties of fire smoke aerosol from in-situ polar nephelometry using GRASP.
  • Retrieving aerosol and surface products via a multi-pixel approach: An analysis of PACE polarimeter HARP2 observations utilizing GRASP.
  • Advancing combined satellite and in-situ measurements for air quality applications.

The AAC 2025 underscores the growing emphasis on multi-instrument synergies – particularly the need to combine lidar, in-situ, and satellite datasets in a coherent retrieval framework. This perspective aligns with ongoing GRASP activities aimed at improving comparability and interpretability of aerosol products across measurement systems.
