Welcome to the 5th APOLO Workshop

Advancement of POLarimetric Observations: instruments, calibration, and improved aerosol and cloud retrievals

SCOPE

The primary topic was remote sensing with light polarization, including, but not limited to:

  • Advances in the theory of polarimetric remote sensing
  • Scattering of light by terrestrial aerosols, clouds, oceans, and land surfaces
  • Polarimetric applications in astrophysics and planetary science
  • Improvement of polarimetric instrumentation quality and information content
  • Development of advanced retrieval algorithms and data processing
  • Upcoming and current satellite missions and field campaigns
  • Long-term calibration and validation
  • Climate modelling, elaborated in situ and ground-based validation observations
  • Models, In situ and Remote sensing of Aerosols (MIRA) Collaborations
  • Polarimetric Missions :
    • Passive: SPEXone, HARP-2, 3MI , HARP-2, CO2M, MAIA, DPC, etc.
    • Active: EarthCARE, Dragon-6, etc.

SCIENTIFIC PUBLICATIONS

The APOLO conferences aim to promote international collaboration and informal, but deep, scientific cooperation on polarimetric observations.

Collections of articles from APOLO-2017APOLO-2019, APOLO-2022 and APOLO-2024 have been published in the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT). We intend to continue this tradition for APOLO-2026.
