It includes a quick start guide for educators and first-hand stories (blogs) for learners of all ages by NASA visualizers, scientists and educators. We hope that your understanding and use of NASA's visualizations will only increase as your appreciation grows for the beauty of the science they portray, and the communicative power they hold. Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.It all began with my fourth grade teacher, Mrs. Benner. Back then my school had a weather station and one day she had asked me to collect wind speed and temperature data. I soon found myself in charge of the morning weather forecast and soon this was my favorite part of the day. Little did I know that in the years that would follow, I’d pursue my passion for clouds and meteorology to become a research scientist at NASA. Working at NASA is every bit as cool as it sounds! Everyday is different and I always find myself working with new scientific tools to uncover mysteries about our planet Earth. Lately I’ve been studying the cryosphere, or the world’s frozen places, where I’m using scientific visualizations to understand the impacts of climate change in the Arctic. In particular I’m focusing on melting sea ice to understand how it affects Arctic cloud formation.Arctic clouds are made up of tiny liquid droplets and ice particles that form from condensation and then freezing of water vapor. Water vapor is a necessary ingredient for Arctic cloud formation, and evaporation from the Arctic Ocean can serve as an important source of water vapor. But when sea ice sits on the Arctic Ocean it acts as a lid that prevents evaporation and may limit Arctic cloud formation. Over the past decade the amount of Arctic sea ice has declined dramatically and we think this trend may be influencing Arctic cloud formation.I created a visualization showing the hypothesized response of clouds to melting in sea ice (below). The difference between the left panel, \"Current Conditions,\" and the right panel, \"Future Conditions,\" is that less sea ice in the future leads to more evaporation, and more evaporation leads to more water vapor and increased cloudiness. This hypothesis is where I base my research, using state-of-the-art NASA satellite instruments including CALIPSO and CloudSAT. || ", "hits": 35 }, { "id": 4307, "url": "https://svs.gsfc.nasa.gov/4307/", "result_type": "Visualization", "release_date": "2015-07-21T13:00:00-04:00", "title": "Impact of Snow Darkening on Boreal Spring Climate", "description": "Figure 1b: This image shows how the reduced albedo of the snow from dust, black carbon and organic carbon (the \"snow darkening effect\") alters difference in snow water equivalent through increased springtime melt.

But until recently, scientists rarely considered the effect of all three major types of light-absorbing aerosols together in climate models.In a new study, NASA scientists used a climate model to examine the impact of this snow-darkening phenomenon on Northern Hemisphere snowpacks, including how it affects snow amount and heating on the ground in spring.The study looked at three types of light-absorbing aerosols – dust, black carbon and organic carbon. Black carbon and organic carbon are produced from the burning of fossil fuels, like coal and oil, as well as biofuels and biomass, such as forests.With their snow darkening effect added to NASA’s GEOS-5 climate model, scientists analyzed results from 2002 to 2011, and compared them to model runs done without the aerosols on snow. They found that the aerosols indeed played a role in absorbing more of the sun’s energy. Over broad places in the Northern Hemisphere, the darkened snow caused some surface temperatures to be up to 10 degrees Fahrenheit warmer than it would be if the snow were pristine. As a result, warmer, snow-darkened areas had less snow in spring than they would have had under pristine snow conditions.According to the study, dust’s snow darkening effect significantly contributed to surface warming in Central Asia and the western Himalayas. Black carbon’s snow darkening effect had a larger impact primarily in Europe, the eastern Himalayas and East Asia. It had a smaller impact in North America. Organic carbon’s snow darkening effect was relatively lower but present in regions such as southeastern Siberia, northeastern East Asia and western Canada.“As we add more of these aerosols to the mix, we are potentially increasing our overall impact on Earth’s climate,” said research scientist Teppei Yasunari at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.Research: Impact of snow darkening via dust, black carbon, and organic carbon on boreal spring climate in the Earth systemJournal: Geophysical Research: Atmospheres, June 15, 2015.Link to paper: http://onlinelibrary.wiley.com/doi/10.1002/2014JD022977/fullHere is the YouTube video. || ", "hits": 59 }, { "id": 4310, "url": "https://svs.gsfc.nasa.gov/4310/", "result_type": "Visualization", "release_date": "2015-05-01T00:00:00-04:00", "title": "Moon Phases Loop", "description": "A looping animation showing a complete cycle of average lunar phases. || moon.0060_print.jpg (1024x576) [57.1 KB] || moon.0060_searchweb.png (320x180) [33.1 KB] || moon.0060_thm.png (80x40) [3.1 KB] || moon_720p30.mp4 (1280x720) [1.5 MB] || moon_1080p30.mp4 (1920x1080) [3.4 MB] || 1920x1080_16x9_30p (1920x1080) [16.0 KB] || moon_720p30.webm (1280x720) [873.0 KB] || moon_2160p30.mp4 (3840x2160) [11.6 MB] || moon_360p30.mp4 (640x360) [401.5 KB] || 5760x3240_16x9_30p (5760x3240) [16.0 KB] || moon_1080p30_4310.pptx [3.9 MB] || moon_1080p30_4310.key [6.3 MB] || ", "hits": 830 }, { "id": 4253, "url": "https://svs.gsfc.nasa.gov/4253/", "result_type": "Visualization", "release_date": "2015-02-04T09:00:00-05:00", "title": "Moon Phase and Libration, from the Other Side", "description": "This narrated video introduces two views of the Moon's far side.

The Earth's tilted axis allows sunlight to fall everywhere on its surface, even at the poles, for at least part of the year. But the Moon's tilt relative to the Sun is only 1.6°, not enough to get sunlight into some deep craters near the lunar north and south poles. PSRs are therefore some of the coldest, darkest places in the solar system.Because of that, PSRs are expected to be excellent traps for volatiles, chemicals that would normally vaporize and escape into space, and this includes water. Lunar Reconnaissance Orbiter (LRO) includes several instruments designed to peer into the PSR darkness and measure temperature, reflectivity, and neutron absorption, all of which are clues to what chemicals might be hiding there.

However, the terrain across the Sahara Desert and Arabian Peninsula is actually quite varied. Darker surface features (like rocks and plant canopies) absorb more light than lighter surfaces (like sand) and therefore get hotter in the afternoon. Over the course of a day, these heating differences can set up atmospheric motions that influence global clouds and rain. || ", "hits": 81 }, { "id": 2214, "url": "https://svs.gsfc.nasa.gov/2214/", "result_type": "Visualization", "release_date": "2001-08-13T12:00:00-04:00", "title": "The Impact of Aerosols on Atmospheric Warming - Version 1", "description": "Bright and dark aerosols, combined with solar heating, create different effects in heating the atmosphere and heating the surface of the Earth.
