/ftp_mirror/atmosphere/lightning/media/thumbnail_small.jpg Annual Lightning Flash Rate Map dataset.php? Id=6 Annual Lightning Flash Rate Map Description Before scientists had satellites to detect and measure lightning frequency, it was thought that there were globally 100 lightning flashes per second, an estimate that dates back to 1925.

Natural History. Emerging Trends. The International Association of Hydrogeologists - IAH / AIH. Scripps Institution of Oceanography, UC San Diego. Resource Collections - BioEd Online. Air, Atmosphere and Living Systems Resources The Air unit lets students creatively explore air and the atmosphere, air quality and related issues such as allergens in the places we live, study and work. All About Food Resources The Food unit allows students to have fun learning about food sources, healthy eating, food safety, food groups and overall nutrition. Experiments in Space Resources Join in real space research conducted on the International Space Station with investigations that enable students to compare organisms (ants, butterflies, plants, spiders) in their classrooms to similar plants or animals grown in space.

This could occur if global warming is sufficient to cause large scale melting of arctic sea ice and the Greenland ice sheet. Such a change in the current may be gradual (over centuries) or very rapid (over a few years). Either would cause planet wide changes in climate. This effect may be part of what starts and stops the ice ages. Ecology and Society.

Northwest African Dust Storm A massive dust storm erupted off the northwestern coast of Africa over this past weekend and seemd to be at its maximum intensity on Sunday, 2 March 2003 as seen in this SeaWiFS true color image.

Phytoplankton Bloom in the Barents Sea A break in the clouds over the Barents Sea on August 1, 2007 revealed a large, dense phytoplankton bloom to the orbiting MODIS aboard the Terra satellite.

Video: Earth from Space. Eyes on the Earth. Earth. Earth Earth is a complex, dynamic system we do not yet fully understand.


The Earth system, like the human body, comprises diverse components that interact in complex ways. We need to understand the Earth's atmosphere, lithosphere, hydrosphere, cryosphere, and biosphere as a single connected system. Our planet is changing on all spatial and temporal scales. The purpose of NASA's Earth science program is to develop a scientific understanding of Earth's system and its response to natural or human-induced changes, and to improve prediction of climate, weather, and natural hazards.
