This is a simpe Javascript program that allows users to calculate the reflection of solar radiation from various surface conditions on Earth. Full description.

Using the European Space Agency's Infrared Space Observatory, Spanish and Italian astronomers have for the first time measured the total amount of water in cold regions of the Milky Way. The findings and implications of this research are discussed here, with emphasis on the fact that water is abundant in these cold regions and exists mostly in the form of ice. Images and videos are included. Full description.

This computer-based lesson provides information on ocean currents, circulation and atmospheric influences. Several sections cover "drift" studies, including the famous Nike Tennis Shoe study. Each segment provides relevant information and gives students questions to answer. Incorrect responses result in more information. This unit is part of an on-line course in general oceanography offered at San ... Full description.

This site was designed to provide explanations of some basic cloud forms and access to detailed pictures of representative examples of each type. Full description.

The purpose of this lesson is to let students analyze atmospheric radiosonde data from a balloon launched at NASA Langley Research Center by teachers attending a workshop. Other resources are included to assist in interpreting the observations. Students are asked to explain in paragraph format their interpretation of the atmospheric conditions depicted by the data and the graph produced using the ... Full description.

Scientists have studied the physical properties of clouds and have developed instruments onboard satellites to characterize the types of clouds they see below. Some satellites have instruments that allow them to measure rainfall as well. For this lesson, students will hypothesize what types of clouds they believe will create the most precipitation (rainfall) over Nashville, TN. Students use the Live ... Full description.

This description of the El Nino pattern in the eastern Pacific is from NASA's Earth Science Enterprise. In addition to text and diagrams, it provides three weather related activities for lab or classroom. Full description.

In this lesson, students will examine a historical Category 5 hurricane, Hurricane Rita, that crossed the Gulf of Mexico during September 18-24, 2005. First, they will use the MY NASA DATA Live Access Server to obtain sea surface temperature (SST) data maps of the Gulf of Mexico. Then, they will construct a time series of SST data (line plot) for a location within the path of the hurricane where a ... Full description.

Solar cells have varying amounts of effectiveness depending on factors such as latitude and cloud coverage. For example, locations with more cloud coverage will produce less solar energy. By comparing the monthly averages of surface downward radiation in various locations around the United States, students can analyze areas that would be more or less beneficial to having solar panels per month. This ... Full description.

In this lesson students will build on knowledge gained in the Hurricane Research lesson and the Hurricane Frequency and Intensity Lesson. Specifically, they will discuss the interaction (pathway) between a specific 'sphere' and the 'event' (hurricane). Working in groups, students will be assigned a specific sphere to look at more closely in relation to hurricanes. When all groups are finished, each ... Full description.
