| Title |
Global Sea Surface Temperature from June, 2002 to September, 2003 (WMS) |
| Abstract |
The temperature of the surface of the world's oceans provides a clear indication of the state of the Earth's climate and weather. The AMSR-E instrument on the Aqua satellite measures the temperature of the top 1 millimeter of the ocean every day, even through the clouds. In this visualization sequence covering the period from June, 2002, to September, 2003, the most obvious effects are the north-south movement of warm regions across the equator due to the seasonal movement of the sun and the seasonal advance and retreat of the sea ice near the North and South poles. It is also possible to see the Gulf Stream, the warm river of water that parallels the east coast of the United States before heading towards northern Europe, in this data. Around January 1, 2003, a cooler than normal region of the ocean appears just to the west of Peru as part of a La Nina and flows westward, driven by the trade winds. The waves that appear on the edges of this cooler area are called tropical instability waves and can also be seen in the equatorial Atlantic Ocean about the same time. |

X-Ray Images of the North Po

| Title |
X-Ray Images of the North Polar Region (WMS) |
| Abstract |
Here are X-rays images (shown on the same brightness scale) of the north polar region obtained by Chandra HRC-I on different days, showing large variability in soft (0.1-10.0 keV) X-ray emissions from Earth s aurora. Note that the images are not snap shots, but are approximately 20-min scans of the northern auroral region in the HRC-I field-of-view. The brightness scale in Rayleighs (R) assumes an average effective area of 40 cm2. The day-night terminator at an altitude of 0 km is displayed with lighting. The day-night terminator at an altitude of 100 km is shown by the blue line. |
