Plantation forestry harvesting near Tokoroa , New Zealand
Published June 16, 2002
Forests are being harvested near Tokoroa, New Zealand, which has been described as the hub of New Zealand’s forestry industry. The large tan areas are cleared forests. The land use pattern that looks like tan beads on a string are clearings used to stock timber before it is sent to pulp and paper mills about 4 kilometers south of Tokoroa. The light green areas around the town are dairy farms.

Egmont National Park, New Zealand
Published June 2, 2002
The lush forests of Egmont National Park, on New Zealand‘s North Island, contrast with the pasturelands outside the circular park boundaries. The unique shape of the park results from its first protection in 1881, which specified that a forest reserve would extend in a 9.6-kilometer radius from the summit of Mt. Taranaki (named Mt. Egmont by Captain Cook). The park covers about 33,500 hectares and Mt. Egmont stands 2518 meters tall. The volcano began forming 70,000 years ago, and last erupted in 1755. A series of montane habitats occur in procession up the flanks of the volcano—from rainforest, to shrubs, to alpine, and finally snow cover.

Thunderstorms over Brazil
Published May 15, 2002
This photograph, acquired in February 1984 by an astronaut aboard the space shuttle, shows a series of mature thunderstorms located near the Paraná River in southern Brazil. With abundant warm temperatures and moisture-laden air in this part of Brazil, large thunderstorms are commonplace. A NASA-funded researcher has discovered that tiny airborne particles of pollution may modify developing thunderclouds by increasing the quantity and reducing the size of the ice crystals within them. These modifications may affect the clouds’ impact on the Earth’s “radiation budget,” or the amount of radiation that enters and leaves our planet.

Aswan High Dam in 6-meter Resolution from the International Space Station
Published May 6, 2002
Astronaut photography of the Earth from the International Space Station has achieved resolutions close to those available from commercial remote sensing satellites—with many photographs having spatial resolutions of less than six meters. Astronauts take the photographs by hand and physically compensate for the motion of the spacecraft relative to the Earth while the images are being acquired.
Mount Everest from the International Space Station
Published April 28, 2002
This detailed image of Everest, the highest (29,035 feet, 8850 meters) mountain in the world, shows early morning light on the eastern Kangshung Face. The mountains appear to jump out of the picture because the image was taken with low sunlight using an electronic still camera equipped with an 800 mm lens.

Coastal Fog, South Peruvian Coast at Pisco
Published April 21, 2002
Coastal fog commonly drapes the Peruvian coast. This image captures complex interactions between land, sea, and atmosphere along the southern Peruvian coast. When Shuttle astronauts took the image in March 2002, the layers of coastal fog and stratus were being progressively scoured away by brisk south to southeast winds.
Rio de Janeiro
Published April 14, 2002
A dengue fever outbreak has plagued Rio de Janeiro since January 2002. Dengue fever is a mosquito-borne disease. The elimination of standing water, which is a breeding ground for the mosquitoes, is a primary defense against mosquito-borne diseases like dengue. Removing such water remains a difficult problem in many urban regions.
