Polar clouds and sulfate aerosols
- Univ. of Colorado, Boulder, CO (United States)
This short article updates work on polar stratospheric clouds (PSCs) with a new picture of PSC formation emerging. Low-temperature liquid sulfuric acid aerosols can absorb significant quantities of HNO3. As temperatures cool, the ternary solutions absorb more HNO3 and H2O. Recent work has indicated that these liquid PSCs may actually activate chlorine more efficiency than frozen NAT particles. 8 refs., 1 fig.
