TOMS Ozone at the South Pole: September Averages from 1979 through 2000

TOMS Ozone at the South Pole: September Averages from 1979 through 2000

The year 2000s Antarctic ozone hole is the largest ever observed. Scientists continue to investigate the phenomenon, and are somewhat surprised by its scale. Using data from NASAs Total Ozone Mapping Spectrometer (TOMS) instrument onboard the Earth Probe satellite, researchers can evaluate and compare current conditions over the south pole to readings taken by other instruments in years past. Continued monitoring of polar ozone levels helps researchers gain a better understanding of how the planets climate may be changing. The following animation shows how ozone loss at the south pole has grown since the mid-80s. Early readings over Antarctica indicate little or no ozone depletion beyond naturally predicted levels. But as the 80s and 90s progress, a clear change in atmospheric chemistry takes place at the bottom of the world. The hole starts small in the late 80s and spreads as subsequent winter cycles break apart ozone molecules. (less)

Looking at transportation and the environment, students learn that some human-made creations, such as vehicles, can harm the environment. They also learn about alternative fuels and vehicles designed by engineers to minimize pollution. The associated hands-on activity gives students a chance to design their own eco-friendly vehicle.

Trends in Snow Cover and Temperature in Alaska

Trends in Snow Cover and Temperature in Alaska

This lesson is designed to help students gain knowledge in using the ... (more)

This lesson is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify and download a microset of data, and then to use the data to compare NASA satellite data observations with surface measurements of snow cover and temperature. Students will obtain snow cover and surface temperature data for a locale in Alaska, plot the data, and then investigate seasonal trends in snow cover, and the relationship between snow cover and surface temperature at that locale. The lesson provides detailed procedure, related links and sample graphs, follow-up questions and extensions, and Teacher Notes. (less)

This lesson is designed to help students gain knowledge in using the ... (more)

This lesson is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify and download a microset of data, then to use the data to investigate tropospheric ozone for several US cities. Using the LAS, student-groups will create line-plots of tropospheric ozone for a particular date and city. From that information they will investigate possible trends in ozone and compare their findings to information found on the EPA Air Quality Index website. The lesson provides detailed procedure, related links and sample graphs, follow-up questions and extensions, and Teacher Notes. (less)

Over the past several decades, the levels of ozone in the atmosphere have received a lot of media and government attention. Major focus has centered on the hole or area of depletion of the ozone layer over the Arctic and Antarctic poles in winter months, which has been found to be due to human emissions of chlorofluorocarbons. This lesson uses SAGE III satellite data and ozonesonde data captured over Thule, Greenland on October 26, 2002. Of major importance is how well the satellite compares to the ozonesonde data. The graph, accessed via the links section, shows how SAGE III corresponds to the ozonesonde data. For this lesson, only data from the stratosphere (above 20 km) are used. The lesson provides an example case study of a validation of NASA satellite data with atmospheric sounding observations of atmospheric ozone levels using either graphing calculators or Microsoft Excel.
