Activities

APARC activities are organised under three themes and address societally-relevant scientific questions related to the atmosphere and its role in climate change.

APARC activities

  • Atmospheric Composition and the Asian Monsoon (ACAM)
  • Assessing predictability (SNAP)
  • CCM initiative (CCMI)
  • Composition Trends And Variability in the Upper Troposphere and Lower Stratosphere (OCTV-UTLS)
  • Dynamical variability (DynVar)
  • Fine-scale Processes (FISAPS)
  • Gravity waves
  • Hunga Tonga-Hunga Ha’apai stratospheric impacts (HTHH)
  • Attribution of Dynamically-driven extremes (LEADER)
  • Ozone Trends (LOTUS)
  • Quasi-biennial oscillation (QBOi)
  • Reanalysis intercomparison (A-RIP)
  • Solar influence (SOLARIS-HEPPA)
  • Stratospheric sulfur (SSiRC)
  • Temperature changes (ATC)
  • Towards Unified Error Reporting (TUNER)
  • Very Short-Lived Substances (VSLS-MIP1)
  • Previous activities
