Measurement stations in the Boston area including two urban sites: Boston University (BU) and Copley Square (COP), and three boundary sites: Harvard Forest (HF), Canaan (CA), and Martha's Vineyard (MVY). Blue shading represents 2014 average afternoon CO2 emissions. See the dataset user guide for more details.

Body

A new dataset from the North American Carbon Program provides atmospheric measurements of CO2 and model estimates of urban emissions at sites near Boston, Massachusetts, USA.
