            "description": "NASA has been monitoring the status of the ozone layer through satellite observations since the 1970s, beginning with the TOMS sensors on the Nimbus satellites. The latest-generation ozone-monitoring technology, the Ozone Monitoring Instrument (OMI), is flying onboard NASA's Aura satellite. The ozone hole is not technically a 'hole' where no ozone is present, but is actually a region of exceptionally depleted ozone in the stratosphere over the Antarctic.  The ozone hole begins to grow in August and reaches its largest area in depth in the middle of September to early October period. In the early years (before 1984) the hole was small because chlorine and bromine levels over Antarctica were low. Year-to-year variations in area and depth are caused by year-to-year variations in temperature. Colder conditions result in a larger area and lower ozone values in the center of the hole.  This animation shows total ozone in the Antarctic region along with the maximum ozone depth and size since the earliest measurements of Earth Probe instrument on the TOMS satellite.  This animation was created for an exhibit at the Smithsonium Museum. Data dropouts have been removed for the following times:  1998/12/14-31, 2002/08/03-11, 2003/11/28-2003/12/02.  The minimum ozone recorded is 82.0 du  on September 26, 2003.  The maximum area of 29 million square kilometers (11.4 million square miles) occurred on September 9, 2000. || ",

            "description": "Biomass burning is the burning of living and dead vegetation. It includes the human-initiated burning of vegetation for land clearing and land-use change as well as natural, lightning-induced fires. Scientists estimate that humans are responsible for about 90% of biomass burning with only a small percentage of natural fires contributing to the total amount of vegetation burned. Burning vegetation releases large amounts of particulates (solid carbon combustion particles) and gases, including greenhouse gases that help warm the Earth. Studies suggest that biomass burning has increased on a global scale over the last 100 years, and computer calculations indicate that a hotter Earth resulting from global warming will lead to more frequent and larger fires. Biomass burning particulates impact climate and can also affect human health when they are inhaled, causing respiratory problems. Here are three images of South America on October 7, 2004. The first image shows clouds and fires on that day. The second image is clouds and nitrous dioxide (NO2) concentrations in the stratosphere. The last image overlays the fires on the NO2 data. || ",
