The pattern of white squares indicates regions where the concentration of tropospheric CO2 is higher than the trend, while regions devoid of the squares are areas where the CO2 concentrations are lower than the trend. The trend was calculated by a least-squares line fit to a moving 8-day global average of CO2 concentration provided by the AIRS instrument on the Aqua satellite, and increases over the course of the animation (Sept. 2002-Sept. 2006) from 374 ppm to 383 ppm. The biosphere data is provided by the SeaWiFS instrument aboard the SeaStar satellite.During spring and summer months, the consumption of CO2 through plant respiration increases, reducing the concentration of CO2 (the white squares) over the more productive areas. In the animation, this is seen as a tendency for the CO2 concentration to drop below the trend over areas of deeper green. The cycle is especially apparent in the Northern Hemisphere. || ", "release_date": "2009-10-09T00:00:00-04:00", "update_date": "2024-06-23T22:01:41.276163-04:00", "main_image": { "id": 495917, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a003600/a003638/carbon_cycle_grid_big_trend.0001.jpg", "filename": "carbon_cycle_grid_big_trend.0001.jpg", "media_type": "Image", "alt_text": "CO2/biosphere correlation, no dates", "width": 1280, "height": 720, "pixels": 921600 }, "main_video": { "id": 495904, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a003600/a003638/CO2_biosphere_w_dates_720p.m2v", "filename": "CO2_biosphere_w_dates_720p.m2v", "media_type": "Movie", "alt_text": "CO2/biosphere correlation, with datesThis video is also available on our YouTube channel.", "width": 1280, "height": 720, "pixels": 921600 }, "main_credits": { "Visualizations by": [ { "name": "Trent L.

For plants, it's the opposite. Tiny pores on leaves absorb carbon dioxide and release oxygen as part of a cellular process that converts sunlight and water into energy. Individually, plants take in small amounts of carbon dioxide from the air, but en masse the world's vegetation behaves like a giant lung that can change the composition of the atmosphere. The visualization below, which is based on data from the MODIS instrument and four years of carbon dioxide measurements from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite, reveals how carbon dioxide concentrations fluctuate due to vegetation cover on land. Here, flashing white squares represent carbon dioxide levels in the atmosphere. Notice a sharp reduction in squares as vegetation thrives during the Northern Hemisphere summer. Conversely, more squares are present in winter as vegetation losses lead to rising carbon dioxide levels across the globe. || ", "release_date": "2012-02-09T00:00:00-05:00", "update_date": "2023-05-03T13:53:16.242474-04:00", "main_image": { "id": 479100, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a010900/a010903/COVER_CO2_biosphere.0054.jpg", "filename": "COVER_CO2_biosphere.0054.jpg", "media_type": "Image", "alt_text": "Watch plants consume carbon dioxide and alter the chemistry of the atmosphere.", "width": 1024, "height": 576, "pixels": 589824 } } ], "sources": [], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
