Terra Spacecraft Open for Business
After a picture-perfect launch into space last December, NASA's premier Earth Observing System Satellite, Terra, has completed on-orbit checkout and verification and is "open for business."
Terra, an international mission and part of NASA's Earth Sciences Enterprise, is opening a new window to the Earth and is providing daily information on the health of the planet. First images from the five instruments aboard Terra are being presented during a press briefing today at NASA Headquarters, Washington, DC.

Arctic Ozone Levels Significantly Low
During the preceding winter Arctic ozone levels reached their lowest point in eight years at an altitude of nearly 60,000 feet. Concentrations dropped more than 50 percent from their average. But measurements taken during the largest international campaign ever mustered to study the Arctic stratosphere are yielding better insights into the processes that control polar ozone. Called SOLVE (Stratospheric Ozone Loss and Validation Experiment), it included researchers from Europe, Russia, Canada, and the United States working together to develop better tools for predicting the state of polar ozone levels. These predictive tools will become more and more important in light of expected chlorine level declines due to the Montreal Protocol and what will likely be increasing levels of greenhouse gases in the coming decades.

Central America from Space
Expansive stretches of Guatemala's Olintepueque and La Esperanza regions have been blackened by wildfires sparked by ongoing hot and dry weather. The image below was captured by SeaWiFS on March 30. Click on pic below for larger image.
This is the March 29th SeaWiFS view of the smoke coming from Central America. In this oblique westward-looking view, Honduras and Nicaragua are in the foreground and El Salvador, Guatemala, Belize, and Mexico are in the background. Click on pic for larger image.

Terra First Light Images
This image (left) of the Mississippi Delta was acquired on February 24, 2000 and is one of the first scenes acquired by the Moderate resolution Imaging Spectroradiometer (MODIS) on the EOS-Terra Spacecraft. The scene was made by combining three of the visible bands of the MODIS Land Surface Reflectance product.
This image is color composite covering the Rift Valley, in land area of Ethiopia. The color difference of this image reflects the distribution of different rocks with the different amount of silicon dioxide. It is inferred that the area with whitish color is covered with basalt, and the area with pinkish color with andesite in center. This is the first image in history for spaceborne TIR multi-band image enabling to distinguish between rocks with same compositions.

Saharan Dust Plume as Big as Spain
A massive sandstorm blowing off the northwest African desert has blanketed hundreds of thousands of square miles of the eastern Atlantic Ocean with a dense cloud of Saharan sand. Click on the TOMS satellite image above for a movie of the dust storm.
The
SeaWiFS image appears to the left.
A broader perspective above shows the size of Saturday's (Feb. 26) Saharan dust plume. Images 2 and 3 provided by the SeaWiFS Project, NASA/Goddard Space Flight Center, and ORBIMAGE

San Cristobal Blows Its Top
On Feb. 23 a long plume is seen extending from San Cristobal, Nicaragua some 100 km over the Pacific Ocean. This is the strongest ash eruption at San Cristobal since the present low level activity began in 1997.

Denmark Taken by Storm
Storms packing winds of 90 mph hit Denmark last weekend (Jan. 29-30), causing widespread flooding and damage. The aftermath of that storm is evident in this image taken by SeaWiFS which shows marked murkiness around the country caused by the storm stirring up the waters.

New Zealand is Stunning!
SeaWiFS captured this photograph of the north island of New Zealand last March. The uninhabited 2 x 2.4 km White Island (just barely visible to the right of the middle of the north island) is the emergent summit of a 16 x 18 km submarine volcano. The white smoke plume emanating from it is barely visible. Intermittent steam and ash eruptions have occurred throughout the short historical period, but its activity also forms a prominent part of Maori legends.

After Dennis and Floyd Blew Through
These two images show the effects that Hurricanes Dennis and Floyd had on North Carolina's estuaries. The picture on top shows the North Carolina coast before either of the two hurricanes came through (April 1999). The image on the bottom shows the estuaries after the hurricanes. There is a marked increase in the muddiness around the shore and in the estuaries due to hurricanes.

Tasmania in Clear View
There looks to be some sort of aerosol over Bass Strait in this relatively clear SeaWiFS view of Tasmania. The phytoplankton coloring the waters south and west of the island highlight the turbulent nature of this part of the ocean.

Haze Over China
This view of Eastern Asia was taken on January 2, 2000 showing the thick layer of haze over southern People's Republic of China, including the cities of Chengdu, Congqing, Wuhan, and the archaeologically important city of Xi'an. Researchers are unclear as to the source of the haze, but it is thick enough to obscure most of the natural colors reflected from the ground beneath.
For more about SeaWiFS
On January 2, 2000, the thick layer of haze over China was also detected by the Total Ozone Mapping Spectrometer (TOMS) instrument onboard the Earth Probe Satellite. While best known for mapping total column ozone on a daily basis, TOMS can also detect and track aerosols located in the troposphere.
The haze is denoted by the TOMS aerosol index. For a given scene, the aerosol index is proportional to the amount of light absorbed before it reaches the ground. Light blue (0.2) indicates smaller amounts of aerosol and dark red (1.6) indicates a greater amount of aerosol (dust or smoke). For reflectivity (grayscale), the lighter tones means that more light is reflected back to space by the clouds. Click on pic to enlarge image for detail.
