Hemispherically-Symmetric Strategies for Stratospheric Aerosol Injection

Four hemispherically-symmetric injection strategies designed to maintain the same global mean surface temperature, plus a more complex strategy. The data supports research comparing how injection location affects climate responses, such as aerosol optical depth and temperature gradients. Yan Zhang from Cornell University produced this data.

Use Cases

• Compare injection efficiency across different latitudes based on the described injection strategies.
• Model spatial distributions of aerosol optical depth (AOD) resulting from different SAI strategies.
• Analyze impacts on equator-to-pole temperature gradients based on high-latitude versus equatorial injection.
• Evaluate the effectiveness of different strategies in restoring Arctic sea ice, as mentioned in the description.

Strengths

• Compares five distinct SAI strategies, including four hemispherically-symmetric ones and a more complex gradient-maintaining strategy.
• Quantifies specific efficiency differences, such as the EQ case requiring 59% more injection than the 30N+30S case for the same cooling target.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
