Before I climb back into the mud pit, I want to share this installment of "Appreciating our Global Heat and Moisture Distribution Engine.  This time I feature four short videos produced by NASA Goddard that do a wonderful job of visualizing various facets of our planet's geophysical reality.  Using state of the art computer graphics based on actual satellite observations they visualize how these varied components seamlessly integrate with each other to create the wonderful planet that we were born into… and the climate system we depend on for everything.

The first one is "Dynamic Earth" a 4.5 minute tour starting with our sun and finishing in our oceans, fascinating presentation, (as are all of these YouTube videos).  Then, "The Ocean: A Driving Force for Weather and Climate" is a 6 minutes long grand tour of the oceans.  Following that, the 3 minute "Aquarius: One Year Observing the Salty Seas - Ocean Salinity & Climate" presents the culmination of Aquarius Satellites first full year of data collection.  Finishing with an excellent 6 minute review of "Earth's Water Cycle."

These visualizations are packed with satellite data and do a wonderfully job rendered our planet as a whole, set again the frigid void of space.  This place we call home is special, nothing else like it in the universe, it's worth getting to know and love and protect.

The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable. This animation helps to convey the importance of Earth's oceanic processes as one component of Earth's interrelated systems.

This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites to measure physical oceanography parameters such as ocean currents, ocean winds, sea surface height and sea surface temperature. These measurements, in combination with atmospheric measurements such as surface air temperature, precipitation and clouds can help scientists understand the ocean's impact on weather and climate and what this means for life here on Earth. NASA satellites and their unique view from space are helping to unveil the vast... and largely unexplored.... OCEAN.

Aquarius: One Year Observing the Salty Seas - Ocean Salinity & ClimateFrom NASA: This video provides a global tour of sea surface salinity using measurements taken by NASA's Aquarius instrument aboard the Aquarius/SAC-D spacecraft, from December 2011 through December 2012. Red represents areas of high salinity, while blue represents areas of low salinity. Aquarius is a focused effort to measure sea surface salinity and will provide the global view of salinity variability needed for climate studies. The mission is a collaboration between NASA and the Space Agency of Argentina (Comisión Nacional de Actividades Espaciales).

Water is the fundamental ingredient for life on Earth. Looking at our Earth from space, with its vast and deep ocean, it appears as though there is an abundance of water for our use. However, only a small portion of Earth's water is accessible for our needs. How much fresh water exists and where it is stored affects us all. This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites as well as cartoons to describe Earth's water cycle and the continuous movement of water on, above and below the surface of the Earth.

Sensors on a suite of NASA satellites observe and measure water on land, in the ocean and in the atmosphere. These measurements are important to understanding the availability and distribution of Earth's water -- vital to life and vulnerable to the impacts of climate change on a growing world population.

Aquarius Studies Ocean and Wind Flows Animation

Aquarius is a focused satellite mission to measure global Sea Surface Salinity. During its nominal three-year mission, Aquarius will map the salinity at the ocean surface to improve our understanding of Earth's water cycle and ocean circulation. ... It will monitor changes in the water cycle due to rainfall, evaporation, ice melting, and river runoff. ... Ocean circulation is driven in large part by changes in water density, which is determined by temperature and salinity. Cold, high-salinity water masses sink and trigger the ocean's "themalhaline circulation" - the surface and deep currents that distribute solar energy to regulate Earth's climate. ...

This composite movie clip contains 10 seconds of surface flows colored by sea surface temperature, followed by 6 seconds of wind currents, followed by 12 seconds of ocean surface currents and 40 seconds of large-scale ocean overturning circulation.

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe.

Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.

The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.  ...
