The atmosphere is a mixture of gases including nitrogen, oxygen, carbon dioxide and other trace gases. Additionally, the atmosphere contains small, suspended liquid and particle matter called aerosols. Aerosols come from various sources, both natural and anthropogenic (man-made). Aerosols are important to study and monitor because they have direct and indirect effects on regional weather and global ... Full description.

One of the strongest observed ENSO events of the century began to unfold in 1997. Fortunately, an extensive network of satellite and ocean buoy instruments was prepared to monitor and record the historical event. In this lesson, students will collect data from the MY NASA DATA Live Access Server to understand how scientists detect the onset of El Nino conditions and the reversal to La Nina conditions ... Full description.

Students will examine data in several formats in order to determine the presence or absence of seasonal variability in tropospheric nitrogen dioxide (NO2) concentrations. The dataset used in this lesson is monthly averages of NO2 as measured from NASA's EOS Aura spacecraft. Full description.

There are several factors that influence the climate or prevailing weather conditions for any given location on Earth. The most important factor is the latitude of the location because that affects the amount of solar radiation received throughout the year. Other factors include its distance from a body of water (its moisture source), elevation and local topography. In this 6 to 10 day unit plan, ... Full description.

Students will make predictions by linking current scientific satellite data to concerns about global climate change. Using maps of sea surface temperature (SST) and ocean surface winds, students will learn how differential heating of Earth results in circulation patterns in the atmosphere and oceans that globally distribute the heat. Students will learn the relationship between the rotation of Earth ... Full description.

Scientists have recently been reporting that the average temperature of the Earth has been rising, usually referred to as 'global warming'. What is the evidence for this change? One piece of evidence could come from patterns of snow (on land) and ice (either sea ice floating on the oceans or glaciers on land) on the Earth - if the snow and ice are disappearing, it would indicate rising average temperatures. ... Full description.

Back in the days of Christopher Columbus, voyages made across bodies of water were dependent upon winds and currents to drive the sailing ships. Thus good navigation routes were often determined by prevailing weather conditions such as the Trade Winds, and then discovered by explorers. In this lesson, students will explore the wind climatology for the Atlantic Ocean basin (as determined by satellite ... Full description.

Students often hear that winters were colder or had more snow in the past. This activity will help them to determine if this is a true or accurate statement for their location. Students will access historic weather information from NOAA and NASA internet resources. They will determine changes in average temperatures, precipitation and cloud cover over time from data and relate global changes to local ... Full description.

El Nino and La Nina are important temperature fluctuations in surface waters of the tropical Pacific Ocean. In this lesson, students will create maps and line graphs of data to compare the effects of El Nino and La Nina at two different longitudinal locations, but at the same latitude, using sea surface temperature and precipitation from real satellite data. Full description.

In this lesson, students will play the role of a senior science advisor for the Louisiana Environmental Agency. Due to the recent damaging and deadly hurricanes during 2005 (i.e., Hurricane Katrina) through 2008, they, along with their team of climatologists, meteorologists, and environmental impact experts, have been tasked to study the danger of future tropical storms. Specifically, they will investigate ... Full description.
