The Stratospheric Aerosol Geoengineering Large Ensemble project (GLENS) is a 20-member ensemble of stratospheric sulfate aerosol geoengineering simulations between 2020-2099 and a 20-member ensemble of control simulations over a reference period between 2010-2030 using the NCAR Community Earth System Model with the Whole Atmosphere Community Climate Model as its atmospheric component. Control and other feedback simulations can be found under the parent dataset.
