Antarctica Greenhouse Gas Emissions: Source-Level Monthly Data Since 2021

Climate TRACE provides greenhouse gas and air pollutant emission estimates for Antarctica, featuring annual country-level data since 2015 and monthly source-level data since 2021. The inventory tracks emissions across various sub-sectors and gases, derived from a global database of over 2.7 million sources.

Use Cases

• Analyzing temporal trends in Antarctic emissions using the monthly source-level data
• Comparing greenhouse gas contributions across different sub-sectors
• Validating climate models against specific gas types and confidence scores

Strengths

• Includes monthly source-level data since 2021
• Provides confidence scores for estimates
• Categorized by sub-sector and gas type

Limitations

• Source-level data starts in 2021
• Relies on modeled estimates rather than direct measurement
• Incomplete ownership fields
