14-Day Boxcar averaged Terra-CERES (Outgoing Longwave Radiation)
Conditions of Use:
Read the Fine Print
Rating

This animation displays one year of Outgoing Long-wave Radiation (OLR) Terra-CERES data (March 1, 2000 to May 25, 2001) with a 14-day boxcar average. Endpoints have the average re-weighted for the smaller amount of data. The data are 2.5 degree resolution.

The 1997-98 El Nino
Conditions of Use:
Read the Fine Print
Rating

El Nino, a periodic warming of the Eastern Pacific Ocean, is among Earths most powerful phenomena. Satellite, ship, and buoy observations show the 1997-98 event as the strongest on record. Visualizing how sea-surface height, sea-surface temperature, and sea-surface winds differ from normal conditions reveals the events magnitude.

The 2003 Antarctic Ozone Hole
Conditions of Use:
Read the Fine Print
Rating

TOMS provides dramatic visual evidence of the annual growth and decay of the Antarctic ozone hole. The ozone losses over Antarctica result from reactions with the products of man-made chlorine and bromine compounds. Because of the tilt of the Earths axis, continuous darkness falls at the South Pole from March 21 to September 21. The dark region in the middle of the July 1 total ozone picture is polar night, where TOMS cannot make measurements. Ozone losses are in blue. Beginning in August, returning sunlight reaches the edges of Antarctica providing chlorine and bromine compounds with energy to rapidly destroy ozone. By mid September, the ozone loss peaks, creating an ozone hole over Antarctic. For more information see www.gsfc.nasa.gov-topstory-2003-1208toms.html

The 2004 Antarctic Ozone Hole
Conditions of Use:
Read the Fine Print
Rating

A relatively warm Antarctic winter in 2004 kept the thinning of the protective ozone layer over Antarctica, known as the ozone hole, slightly smaller than in 2003. Each year the hole expands over Antarctica, sometimes reaching populated areas of South America and exposing them to ultraviolet rays normally absorbed by ozone. Scientists have new tools to study this annual phenomenon, and the human-produced compounds that contribute to ozone breakdown are decreasing. On September 22, 2004, ozone thinning over Antarctica reached its maximum extent for the year at 24.2 million square kilometers (9.4 million square miles). The largest maximum area on record was 29.2 million square kilometers, in 2000. On October 5, 2004, the ozone layer reached a low value of 99 Dobson Units.

20-Year Arctic Autumn Seasonal Surface Temperature Trend
Conditions of Use:
Read the Fine Print
Rating

Here the 20-year seasonal surface temperature trend for the autumn is shown over the Arctic region. This animation shows the warming and cooling regions in steps from the regions of least change to the areas of greatest change. Blue hues indicate cooling regions; red hues depict warming. Light regions indicate less change while darker regions indicate more. The temperature scale used ranges from -0.4 to +0.4 degrees Celsius in increments of .02 degrees. (See color bar below)
