YBTS Project Abstracts and Outcomes
1. Air Masses of the Earth

Abstract: This activity introduces the student to the five basic air masses that affect weather in our hemisphere. Using real-time satellite imagery, the student will then locate the probable location of these air masses and predict current movements.

Outcomes: The student will be able to identify the five air masses that typically affect the weather in the Northern Hemisphere. The student will be able to identify the current location of these air masses using satellite imagery. The student will label a map of the Northern Hemisphere with the correct location of the air masses. The student will predict where these air masses are travelling or if they are stationary. The student will gain an introduction to fronts that relate to the boundary of air masses.

2.Atmospheric Absorption

Abstract: This activity discusses the atmospheric absorption spectrum. The student will determine the extent to which each channel is affected by atmospheric absorption and form a hypothesis about which channels are most likely to make accurate surface temperature measurements. The student will then test this hypothesis by taking temperature measurements in all the infrared channels and comparing them to ground truth data from ground stations and specialized sea surface temperature satellites. He/she will then quantify the deviation of the GOES surface temperature measurements from the ground truth data to confirm or negate the hypothesis.

Outcome: The student will learn about the absorption spectrum of various atmospheric constituents and use his or her knowledge about atmospheric absorption to form a hypothesis that answers the question, "Which GOES channels can be used to make surface temperature measurements?" The student will be able to cross reference ground truth data with satellite data to quantify the accuracy achieved by various satellite channels.

3. Climbing to New Heights

Abstract: This activity involves students in the process of indentifying cloud types and movement from a satellite image and gathering data through a 48-hour period. Lifting mechanisms that produce clouds will be investigated and the influence of topography on cloud development will be described. This activity should follow successful completion of the basic series of website activities.

Outcomes: The student will distinguish between the various cloud types, identify areas of cloud development in a satellite image, construct a loop of GOES images showing cloud formation and movement. Students will track cloud movements over the continental United States recording changes in altitute and temperature as influenced by topography.

4. Graphing Cloud Height vs. Temperature

Abstract: The student will create a data table of cloud height and temperature, using derived image channels and latitute/longitude coordinates to locate points, and create a graph of cloud height vs. temperature by plotting these points on an x-y axis. Once the graph has been created, the student must draw conclusions about the mathematical relationship between cloud height and temperature and its effect on the weather.

Outcomes: The student will be able to use the GVAR software to locate specific points and create a data table. The student will be able to plot a graph on an x-y axis. The student will determine if a graph represents a direct, inverse, or nonexistent relationship between two variables.

5. Cold Fronts - A Violent Meeting

Abstract: This activity will cover the development of cold fronts and link their movement to the overall movement of air masses on the Earth.

Outcomes: The student will understand the dynamic forces that create a cold front, and locate a cold front using satellite imagery. The student will be able to indicate a cold front on a weather map. The student will create a hypothesis and test this hypothesis using satellite interpretation.

6. The Coriolis Effect

Abstract: This activity will explore the causes of the Coriolis Effect and analyze how this effect determines wind movement and weather throughout the globe. Students will learn the science behind the Coriolis Effect by examining various websites and doing some hands-on demonstrations. Satellite images will then be used to analyze the global impact of this.

Outcomes: The student will be able to describe the mechanism that causes the Coriolis Effect. The student will be able to demonstrate the Coriolis Effect using at least two methods. The student will be able to predict high and low pressure from the air movement in satellite images.

7. The Diurnal Cycle

Abstract: This activity will introduce the diurnal cycle and its effects on the global processes that shape our earth. It begins with an introduction to the mechanisms that drive this heat cycle and continues by having students track this with real-time satellite images.

Outcomes: The student will develop a comprehensive understanding of the diurnal cycle, identify the diurnal cycle in film loops of infrared satellite images, and create a surface temperature chart of various regions of the globe a different times of day. Students will create a line graph of the temperature data.

8. Fire Detection with GOES Data

Abstract: This activity will allow the student to find fires that have been detected on the Internet and then find and track fires with real-time data. This activity also encompasses respones of different IR channels to sub-pixel heat sources, a fire product made by combining information from two channels, and colorizing data through the creation of a color palette.

Outcomes: The student will understand different applications of IR2 and IR4 channels, experience the effect of combining data from multiple channels of the electromagnetic spectrum use Internet data to verify fires detected with GOES data, and detect fire hot spots using GOES data. The student will be able to distinguish between different features of an image by creating a color palette, and to locate fires by detecting smoke plumes.

9. The Gulf Stream

Abstract: This activity allows students to study the Gulf Stream. In doing so, students can isolate the Gulf Stream with a color palette, track its activity over long periods of time, create loops of Gulf Stream movements, and relate to Gulf Stream activity to other environmental factors.

Outcomes: The student will be able to explain the nature of the Gulf Stream, explain the factors that cause this phenomenon, locate the Gulf Stream and isolate it with a color palette, and track the movement of the Gulf Stream by measuring changing distances from points on the Eastern coast of the U.S. The student will be able to create a loop to visualize changes in the Gulf Stream over time.

10. High Level Clouds - What's up?

Abstract: This activity will involve identifying clouds in the high level cloud group. It will cover the development of these clouds and the weather associated with the different clouds in this group.

Outcomes: Students will be able to identify clouds in the high cloud grouping by picture identification and satellite imagery identification. Students will classify clouds into separate groups and create a cloud library of these clouds. Students will predict what type of weather an area had, is having and is going to have based on the types of clouds that are present. Students will use a combination of visible and infrared imagery.

11. The Jet Stream

Abstract: This activity allows students to detect the jet stream in channel 3 and channel 4 imagery and monitor its changes over time. This activity also allows students to correlate the jet stream with other weather phenomena, such as air masses, clouds, and storms.

Outcome: The student will be able to identify the jet stream using satellite imagery. The student will be able to explain the global impact of the jet steam.

12. Intertropical Convergence Zone

Abstract: This activity will examine an area of the globe called the Intertropical Convergence Zone (ITCZ). The student will gain a general understanding of what causes this phenomenon and will chart the movement of this climatological zone with the passing of the seasons. The student will correlate convective activity at the ITCZ with other satellite data on the Internet and research the implications of this area on the global earth processes.

Outcomes: The student will be able to explain the development of the ITCZ and how it affects global weather, and locate the ITCZ using satellite images. The student will create a chart of the movement of the ITCZ over time.
