NOAA’s Earth System Research Laboratory (ESRL) pursues a broad and comprehensive understanding of atmosphere and climate in the earth system. They collect data about greenhouses gases like carbon dioxide (CO2) and methane, aerosols, and ozone from around the world, all the time—that you can see and analyze. Many of their atmospheric samples are processed in INSTAAR labs.
The Interactive Atmospheric Data Visualization (IADV) website is a data exploration tool for the trace gases measured by NOAA ESRL.
Carbon Tracker calculates carbon dioxide (CO2) uptake and release at the earth's surface over time. It shows the ultimate record of the combined human and natural influence on greenhouse gas levels.
Teachers: ERSL's Educational Resources include student activities (grades 4-12) on meteorology, climatology, maps of land and sea, emissions, the carbon cycle, hurricanes, epidemiology, and space science; and educational graphics on global climate change and the greenhouse effect.
