This work shows that information on boundary-layer cloud condensation nuclei could reduce hashtag#aerosol forcing uncertainty by about one third.

What’s next?

  • We need to derive this information accurately from satellites, which is now feasible for 🛰️ SPEXone/PACE and EarthCare. This is also an ongoing work at SRON.
  • Improving modeled anthropogenic aerosol perturbation (e.g., via PPE and data assimilation) is also crucial, as it contributes the second-largest uncertainty in observation-based forcing.
