Studying the Earth Using Satellites GRADE Author: J. Haase and D. Warren Lesson #: 3 ​ ​ 5 Unit Title: Hawaiʻi as an ESS Lab Time Frames: Two 50­Minute Periods ​ ​ Studying the Earth Using Satellites ABSTRACT This lesson introduces students to satellites and satellite applications for studying Earth system science. In the first part of the lesson the students will learn about the parts of a satellite, complete a worksheet and actively build a satellite as a collaborative jigsaw activity. In the second session of the lesson, students will learn about how scientists are currently using satellites to gather data on a range of Earth system science topics. Students will work with one data set collected from a satellite to analyze and consider using satellite data collection as part of Earth system science. Students will develop ideas and questions about how the satellite data can be used to study the four spheres in Hawai‘i and record these in their science notebook. PLANNING INSTRUCTION ASSESSMENT STANDARDS REFERENCES BACKGROUND INFORMATION FOR TEACHERS Satellite data comes in many forms and research topics designed as “missions”. NASA has an increasing number that are specific to the study of Earth System science. There are exciting possibilities to further study Hawaiʻi and the Pacific. Satellites contain instruments that collect raw data remotely through various sensors. The data is transmitted using radio waves to other satellites, and computers and scientists on Earth. This data must be analyzed and processed in context to be useful to scientists. For an example, view the following video which describes how the Global Precipitation Measurement project processes its satellite data: ● NASA Precipitation Education website: ​ http://pmm.nasa.gov/education/videos/data­downpour The dictionary definition of a satellite is “a body that orbits a larger body”. For this lesson we will be using satellite as a man made technology placed in orbit around the Earth or moon or another planet to collect ​ information. Students will be familiar with satellites and how we use satellites today for televisions, weather ​ forecasting, cell phones, GPS tracking (made of 20 satellites working together), navigation and monitoring of natural resources. Yet students may not know much about how satellites work or why they are useful to Earth system scientists. _______________________________________________________________________________________________________________________________ © Bishop Museum, 2015. 1 NASA Earth Observation System has placed many satellites into orbit with missions to study Earth and changes over time. Collecting valuable data on the Earth is like taking the “vital signs” to see what the current levels and indicators of health are in a patient. The Earth’s vital signs are useful in seeing and tracking changes over time and will help us work to find solutions and adjustments associated with climate change.

A keystone of constructing the first satellite collaboratively as a class is highlighting that engineers must work together, especially with demanding projects such a satellites. Later in this unit, students will be working in teams to design a research mission and will be building a team satellite to study a research question for their chosen Hawaiian species. In the second session of this lesson, students will be working with one data set collected from the The ​ Global Precipitation Measurement (GPM) mission. GPM is an international network of satellites that provide ​ the next­generation global observations of rain and snow. (Refer to the additional resources section of this lesson plan to investigate further on the GPM program.) There are many relevant connections for the Hawaiian Islands. Students at the University of Hawaiʻi Small Satellite Program have worked on satellite technology and made a launch in 2013. The following video and article gives a brief synopsis of the satellite technology being designed and applied right here in Hawaiʻi. This video may inspire elementary students and influence career pathways in Engineering. ● University of Hawaiʻi News website: ​ https://www.hawaii.edu/news/2013/11/20/satellite­built­by­uh­students­launched/ PLANNING Essential Questions ● What can data from NASA satellites tell us about Hawaiʻi and the Pacific Ocean? ● In what ways can Earth system scientists use satellite data to study and solve problems in Hawai‘i? Instructional Objectives Students will: ● Investigate the parts of a satellite through a collaborative class jigsaw activity ● Discover how NASA satellite data is collected and processed by watching two short videos ● Recognize how scientists are using satellite data on a range of Earth system science topics. ● Use precipitation data collected from satellites to compare rainfall in Hawaiʻi with other locations. ● Write their thoughts about the essential questions in their science notebooks.

Display on the projector screen the image of multiple satellites orbiting Earth. Here is a link to this image: Image of Satellites of GPM: http://pmm.nasa.gov/image­gallery/gpm­constellation and ask ​ ​ the questions: ● What is a satellite? ● What do satellites do? ● What are the parts of a satellite? 2. Give the students time to discuss their answers in a Think­Pair­Share format. Class generated ideas of how satellites are used may include: weather monitoring, communication, migration tracking, navigation, military intelligence and climate monitoring. Class generated ideas of parts of a satellite will vary. Record student ideas on the board in a two column format. 3. Create a class definition of a satellite, write the definition on the board and have students write it into their science notebooks. _______________________________________________________________________________________________________________________________ © Bishop Museum, 2015. 4 Images courtesy of J. Haase. 5. The next activity is a whole class collaborative construction process where the students will build a model satellite in the front of the class in order to learn more about the parts of a satellite. These are basic satellite parts and will give students an idea of what they will need to include later in the unit when they build their own satellites with a team. 6. Before beginning you can have the students brainstorm what household and recycled items could be used to construct a model of a satellite. Remind students to think about how design elements need ​ to match the function of their work on the satellite. 7. Communicate to students that in order for a satellite to work effectively, several different subsystems must work together and many different engineers and technicians must

  • Cloudsat CALIPSO
    www.nasa.gov andSpaceAdministration National Aeronautics & CloudSat CALIPSO Clean air is important to everyone’s health and well-being. Clean air is vital to life on Earth. An average adult breathes more than 3000 gallons of air every day. In some places, the air we breathe is polluted. Human activities such as driving cars and trucks, burning coal and oil, and manufacturing chemicals release gases and small particles known as aerosols into the atmosphere. Natural processes such as for- est fires and wind-blown desert dust also produce large amounts of aerosols, but roughly half of the to- tal aerosols worldwide results from human activities. Aerosol particles are so small they can remain sus- pended in the air for days or weeks. Smaller aerosols can be breathed into the lungs. In high enough con- centrations, pollution aerosols can threaten human health. Aerosols can also impact our environment. Aerosols reflect sunlight back to space, cooling the Earth’s surface and some types of aerosols also absorb sunlight—heating the atmosphere. Because clouds form on aerosol particles, changes in aerosols can change clouds and even precipitation. These effects can change atmospheric circulation patterns, and, over time, even the Earth’s climate. The Air We Breathe The Air We We need better information, on a global scale from satellites, on where aerosols are produced and where they go. Aerosols can be carried through the atmosphere-traveling hundreds or thousands of miles from their sources. We need this satellite infor- mation to improve daily forecasts of air quality and long-term forecasts of climate change.

  • Cloudsat Overview
    CloudSat Overview CloudSat will provide, from space, the first global survey of cloud profiles and cloud physical properties, with seasonal and geographical variations, needed to evaluate the way clouds are parameterized in global models, thereby contributing to improved predictions of weather, climate and the cloud-climate feedback problem. CloudSat will measure the vertical structure of clouds and precipitation from space primarily through 94 GHz radar reflectivity measurements, but also by using a combination of observations from the EOS-PM Constellation of satellites (A-Train). CloudSat will fly in on-orbit formation with the Aqua and CALIPSO satellites, providing a unique, multi-satellite observing system particularly suited for studying the atmospheric processes of the hydrological cycle. 1. Science Objectives • Evaluate the representation of clouds in weather and climate prediction models. CloudSat will provide a global survey of the vertical structure of cloud systems: This vertical structure is fundamentally important for understanding how clouds affect both their local and large-scale atmospheric and radiative environments. • Evaluate the relationship between cloud liquid water and ice content and the radiative properties of clouds. CloudSat will estimate the profiles of cloud liquid water and ice water content. These are the quantities predicted by cloud-process and global-scale models alike and determine practically all important cloud properties, including precipitation and cloud optical properties. CloudSat will provide coincident profile information on the bulk cloud microphysical properties matched to cloud optical properties. Optical properties contrasted against cloud liquid water and ice contents provide a critical test of key parameterizations that enable calculation of flux profiles and radiative heating rates throughout the atmospheric column.

OCO will make the first global, space-based measurements of atmospheric CO2 with the precision, resolution, and coverage needed to characterize sources and sinks of this important green-house gas. These measurements will improve our ability to forecast CO2-induced climate change. OCO will fly in a 1:15 PM sun-synchronous orbit, sharingits groundtrack with the Earth ObservingSystem (EOS) Aqua platform. It will carry high-resolution spectrometers to measure reflected sunlight in the molecular oxygen (O2) A-band at 0.76 m and the CO2 . X bands at 1.61 and 2 06 m to retrieve the column-averaged CO2 dry air mole fraction, CO2 . A comprehensive validation X and correlative measurement program has been incorporated into this mission to ensure that CO2 can be retrieved with precisions of 0.3% (1 ppm) on regional scales. © 2004 Elsevier Ltd.
