Amazon Drought and Forest Production Decline

A drought that affected large areas of the Amazon rainforest in 2010 triggered the release of about 1.8 million tons of carbon dioxide. After combining a NASA carbon cycle simulation model and satellite data that reflects the “greenness” — or light interception capacity — of forest canopies, researchers found that net primary production in some forest areas decreased by an average of 7 percent compared with 2008 data.

This map shows the change in annual net primary production (NPP) across the Amazon rainforest between 2008 and 2010. The dark red zones illustrate regions where the decline was greatest. All measurements are shown in units of grams of carbon per square meter per year. (Environmental Research Letters)
