Understanding the variability of the density of ocean water is critical to understanding changes in the ocean's circulation, particularly those parts of the circulation that pertain to climate. In the tropics, the sun warms the surface water and causes that water to expand. Because the surface water is now less dense than the cooler water below, the warmest waters remain near the surface. Near the poles, the energy input by the sun is not as strong, and the surface waters are not warmed to the...

Gas Purification Process - Most of the landfill gas purification process involves removing water. This animation shows four major steps to purifying the landfill gas for Goddard. First, placed throughout the landfill purification plant, filters sift out tiny trash particles and water. Second, a compressor squeezes out more water. Third, pipes cool gas drooling out even more water. Finally, the gas is reheated and transported to Goddard. Warm gas reduces moisture. Note: This animation shows four...

The Water Cycle - Water falling from summer storm clouds onto a field of wheat today will someday fall again somewhere else. This is the essence of the water cycle. The first step in the cycle is evaporation. Heated by sunlight, liquid water turns to vapor and enters the atmosphere. Another source of atmospheric water vapor is the respiratory process of plants. Vapor leaves plants through tiny pores called stomata. This process is called transpiration. As moist air ascends into the atmosphere...

The following animation helps to explain the dynamics of subglacial water exchange and what it looks like from space. Starting from an artist's concept of the Antarctic surface we move down to a cross section of the ice sheet with lakes hidden deep beneath. As pressure is exerted on one lake, the water in it is forced to an adjacent lake. This water movement results in elevation changes at the surface over both lakes, detectable by NASA satellites. The camera then moves to a 'top-down' view of...

In winter, moist air flows off the ocean and rises over the hills downwind of a coastal city, dropping its rain and snow mainly as it ascends the hills. As pollution from the city is pushed into the clouds by the hills downwind of the city, it interferes with droplet formation in the clouds as observed by NASA's satellites. The smaller cloud droplets convert more slowly into precipitation. Instead of precipitating, much of the water in the clouds evaporates, reducing the net rainfall downwind...

To some extent, geodesy is the study of the shape of the Earth. But it is also the study of how to find precise locations on the planet. As it relates to the study of sea level, geodesy becomes vital. The Earth is not a perfect shape and is constantly changing. Only through a very carefully constructed system of analysis can scientists achieve the necessary accuracy about the planet's shape (the so-called 'geoid') to make measurements of sea level from space. In this animation we look at how a...

Like clouds in other parts of the atmosphere, one element required for polar mesospheric clouds to form is tiny dust particles on which water vapor can accumulate and grow into ice crystals. Nearer to Earth's surface, clouds form from 'cloud condensation nuclei' that can be sea salt spray, desert dust, or other materials lofted from the surface. In the mesosphere it is thought that cosmic dust particles falling into the Earth's atmosphere might serve this same purpose, and the Cosmic Dust...

The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space.

Cities tend to be 1-10 degrees Fahrenheit warmer than surrounding areas. The added heat destabilizes and changes air circulation around cities. During the warmer months, the added heat creates wind circulations and rising air that produces new clouds enhances existing ones. Under the right conditions, these clouds evolve into rain-producers or storms. Scientists suspect that converging air due to city surfaces of varying heights, like buildings, also promotes rising air needed to produce clouds...

New studies show that the Sun's active regions -- areas of intense eruptions -- are formed from many small magnetic structures (white loops) that rise from deep within the interior, then pierce the surface to form sunspots (dark areas). These structures appear as giant arches when electrified gas (plasma) passes through their magnetic fields. Note: Magnetic field lines poke through the solar surface, producing sunspots and occasionally flares. Animator: Walt Feimer (HTSI).

Understanding the variability of the density of ocean water is critical to understanding changes in the ocean's circulation, particularly those parts of the circulation that pertain to climate. In the tropics, the sun warms the surface water and causes that water to expand. Because the surface water is now less dense than the cooler water below, the warmest waters remain near the surface. Near the poles, the energy input by the sun is not as strong, and the surface waters are not warmed to the...

Reigning on Earth's Climate - Only about 70% of the solar energy that reaches Earth is absorbed, while the other 30% is reflected back into space by atmosphere and aerosols, ocean/land and clouds. A closer view reveals a delicate balance between absorption and reflection as well as a release of energy by rocks, air and sea warming and emitting increasing amounts of thermal radiation (heat) in the form of long-wave infrared light. This radiation allows Earth to lose heat at the same rate it...

On Friday, August 1, 2008, a total eclipse of the Sun is visible from within a narrow corridor that traverses half the Earth. The path of the Moon's umbral shadow begins in Canada and extends across northern Greenland, the Artic, central Russia, Mongolia and China. A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes northeastern North America, most of Europe and Asia.

Methane is a simple compound made of carbon and hydroge. This gas comes from ordinary sources, like cattle herds and garbage dumps. On a planetary scale it also has a significant impact on climate. As it builds up in the atmosphere, it traps energy from the sun like a layer of insulation. Carbon dioxide does much the same thing-it causes global warming by trapping heat. But as experts struggle to curtail global climate change, a decrease of atmospheric methane might be easier to achieve than...

The Aeronomy of Ice in the Mesosphere (AIM) mission will provide the first detailed exploration of the Earth's unique and elusive noctilucent or night shining clouds that are found literally on the 'edge of space'. Located near the top of the Earth's mesosphere (the region just above the stratosphere), very little is known about how these polar mesospheric clouds form or why they vary. They are being seen at lower latitudes than ever before and have been growing brighter and more frequent,...

Carbon And The Ocean -- The Slow Cycle - The oceans are vast, and their processes as complex as their waters are deep.Phytoplankton absorbs carbon dioxide from the atmosphere and nutrient rich waters and grows in wide colonies called blooms. These blooms are highly dependent on surrounding environmental conditions. As phytoplankton grows, it forms the foundation for the food chain, thus passing carbon up to higher life forms.

Normal rainfall droplet creation involves water vapor condensing on particles in clouds. The droplets eventually coalesce together to form drops large enough to fall to Earth. However, as more and more pollution particles (aerosols) enter a rain cloud, the same amount of water becomes spread out. These smaller water droplets float with the air and are prevented from coalescing and growing large enough for a raindrop. Thus, the cloud yields less rainfall over the course of its liftime compared...

As part of the ocean conveyor belt, warm water from the tropical Atlantic moves poleward near the surface where it gives up some of its heat to the atmosphere. This process partially moderates the cold temperatures at higher latitudes. As the warm water gives up its heat it becomes more dense and sinks. This circulation loop is closed as the cooled water makes its way slowly back toward the tropics at lower depths in the ocean. If the poles warm, it is possible that melt water from glaciers and...
