Remote sensing to measure carbon dioxide

Carbon dioxide (CO₂) is the most important greenhouse gas that is increasing in concentration because of human activities.

Climate modelers use satellite data to study CO₂ global distribution and transport and to improve their models.

The map shows patterns of high CO₂ (in red) especially in the Northern hemispher. And indeed, release of CO₂ from fossil fuel burning is higher in the Northern hemispher than in the Southern hemispher.

Question: Can satellites measure global change ?
