Sentences with phrase «tropospheric aerosols»
Tropospheric aerosols are tiny particles suspended in the Earth's atmosphere. They include things like dust, pollution, smoke, and even natural substances like sea salt and pollen. These aerosols can come from both natural and human activities and have various effects on the climate and weather, such as reflecting or absorbing sunlight, influencing cloud formation, and affecting air quality.

It would seem that before pollution laws really take effect, assuming constant economic growth, both the rate CO2 output and cumulative CO2 grow exponentially — but so do is the rate of reflective tropospheric aerosol emission — and the effects roughly cancel one - another.
Human - made tropospheric aerosols, which arise largely from fossil fuel use, cause a substantial negative forcing.
Hence, the mechanism appears to show why both twenty - first century and time - invariant CO2 forcing lead to similar values of φ in climate models despite the presence of transient ocean heat uptake, whereas twentieth century forcing — which has a significant spatially confined anthropogenic tropospheric aerosol component that breaches the first condition — leads to modelled values of φ that vary widely amongst models and in time.
This early success led to the ambitious Global Atmospheric Measurements Experiment on Tropospheric Aerosols and Gases (GAMETAG) project in 1977 — 1978.

Easter specializes in modeling tropospheric aerosols and trace gases and their interactions with clouds and precipitation.
Tropospheric aerosols play a crucial role in climate and can cause a climate forcing directly by absorbing and reflecting sunlight, thereby cooling or heating the atmosphere, and indirectly by modifying cloud properties.
