Movie   ID   Title
NASA has monitored changes in Antarctic ozone levels since 1979. In September 2002, the Antarctic ozone hole split into two parts.   3264   Smithsonian Exhibit: Antarctic Ozone Sequence 1979 through 2004
NASA has been recording ozone values since 1979. This animation shows high concentration of ozone in red. It shows low concentration of ozone, also known as the ozone hole, in purple. Notice that the Ozone Hole did not develop until the mid 1980s.   3137   Antarctic Ozone Sequence 1996 through 2004, Data Dropouts Removed
The TOMS instrument on the Earth Probe spacecraft has recorded daily ozone values from July 25, 1996. Areas of red show the highest concentration of ozone measured in dobson units, DU. Areas of purple indicate the lowest concentration, commonly known as the ozone hole. The top plot shows the amount of ozone concentration measured in DU. The bottom plot shows the spatial area in Millions of Kilometers, MKm, of the ozone hole.   3136   Antarctic Ozone Sequence 1996 through 2004
This animation shows a flat map version of the southern polar vortex at 550 degrees Kelvin during part of 2004.   3098   Polar Vortex (WMS)
Fires seen from space on October 7, 2004   3075   Biomass Burning over South America
This image is of Nitrogen Dioxide, NO2, on October 16, 2004.   3074   Nitrogen Dioxide concentration over China from September 24, 2004, to November 7, 2004
This image shows Nitrogen Dioxide (NO2) from October 8, 2004 on top of the Earth at Night image. Nitrogen Dioxide concentration is clearly evident over the San Diego, Los Angeles, Phoenix, Denver, Houston, Dallas, Chicago, Detroit, Cleveland, Toronto, Birmingham, Washington DC, Philadelphia, and New York. Clouds that obscure the satellite's ability to measure NO2, cover several other urban areas like Kansas City, St. Louis, and Atlanta.   3073   NO2 concentration over the United States from September 24, 2004, through November 7, 2004
September 28, 2004 : Areas of red represent high levels (50+ DU) and areas of blue represent low areas (20 DU).   3071   AURA/OMI Tropospheric Ozone On a Flat Map
October 12, 2004   3070   AURA/OMI Tropospheric Ozone over Indonesia
October 12, 2004   3069   AURA/OMI Tropospheric Ozone over South America and Africa
October 12, 2004   3068   AURA/OMI Tropospheric Ozone over South America
In 2004, the maximum ozone hole occurred on September 22, 2004.   3067   Aura/OMI Ozone Hole from September 12, 2004 to November 15, 2004 with Polar Vortex Demarced
In 2004, the maximum ozone hole occurred on September 22, 2004.   3066   Aura/OMI Ozone Hole from September 12, 2004 to November 15,2004
