Sulfate geoengineering has been proposed as an affordable and climate-effective mean to temporarily offset the warming produced by the increase of well mixed greenhouse gases (WMGHG). The direct radiative effects of sulfur injection in the tropical lower stratosphere can be summarized as increasing shortwave scattering and increasing longwave absorption. Indirect radiative effects are related to induced changes in the ozone distribution, stratospheric water vapor abundance, formation and size of upper tropospheric cirrus ice particles and lifetime of longlived species. A review of these effects will be presented in this seminar, focusing mainly on results from the ULAQ-CCM model, together with some ideas on how to continue the research in the next years.
