Earth Observation is the process of studying our planet’s natural environment. Earth observation has been going on for a long time. Someone might have taken a look at the sky and said ‘look, it looks like the sun is shining!’ or, more likely, they would have observed plants and insects in their environment to help them grow food or make something. Today, we have a lot more technology to help us observe our planet. We can use satellites to take pictures of the Earth, or we can use weather balloons to measure air pressure, temperature, and other things. We can also use airplanes to take pictures of the Earth from high up in the sky.
All of these techniques have helped us learn a lot about our planet, and we are still learning more every day. One of the biggest benefits of Earth observation is that it can help us understand how our planet is changing. We can see what is happening on the ground, and we can also use this information to make predictions about what might happen in the future. Earth observation has many other benefits too. For example, it can help us find new sources of energy, and it can help us protect our environment.
What is Earth Observation?
Earth observation is the process of acquiring data about Earth from outer space. Earth observation systems are deployed on satellites, aircraft, and land instruments to acquire information about all aspects of the Earth’s environment. Applications of Earth observation data include weather forecasting, mapping and resource management, disaster management, land use planning, and climate change research.
The Earth observation system provides data that is essential for the understanding of global change, including climate, land use, environment and security. The Earth observation system builds understanding of global change by providing data that is essential for the understanding of the Earth’s environment, economy and society. Earth observation data is essential for understanding climate, mapping land uses, managing natural resources and monitoring environmental changes.
Why should people study the Earth?
People should study the Earth because it is our home and we need to take care of it. The Earth can be a teacher if we pay attention to what is happening on its surface. By understanding the climate, weather, and land use, we can make better decisions about how to use resources and protect the environment.
The Earth is also a resource. It contains oil, gas, coal, and other minerals that we need to survive. We can use these resources to power our vehicles and homes, but we must be careful not to damage the Earth’s environment. If we study the Earth, we can learn about our planet and how we can protect it for future generations.
What can people learn about the Earth from the data collected via Earth Observation?
There are many ways people can learn about the Earth from data collected
One of the biggest challenges facing Earth Observation is ensuring that the data collected is accurate and reliable. Additionally, there are ongoing efforts to improve the way data is processed and analyzed, so that it can be used more effectively to help understand the Earth.
Key areas of research / technologies for monitoring the Earth
Monitoring the Earth is a challenging task that requires a variety of techniques and technologies. Here are some key areas of research / technologies for monitoring the Earth:
Remote Sensing: Remote sensing is a technology that uses electromagnetic radiation to image or measure objects or locations outside of the observer’s visible range. Common remote sensing techniques include radar, optical imaging, and microwave imagery.
Earth observation satellites are one type of remote sensing tool that can provide images of the entire planet in high resolution. The Atmospheric Infrared Sounder (AIRS) on NASA’s Aqua satellite has been producing global maps of water vapor since 1997. The Advanced Very High Resolution Radiometer (AVHRR) on NASA’s Terra satellite produces images of land cover, ice sheets, clouds, fires, and other disturbances every day.
Global Navigation Satellite Systems (GNSS): A GPS system sends signals from satellites into Earth’s atmosphere to create a consistent position on a grid. GNSS receivers use these signals to determine your location down to within meters. Different types of GNSS receivers are used for navigation applications such as smartphones and marine vessels. There are also multiple civilian and military applications for GNSS including disaster relief and surveillance.
The two main GNSS systems in operation today are Global Positioning System (GPS) and GLONASS. European Union launched Galileo in 2011 as an advanced replacement for GPS which will be more accurate at low signal-to-noise ratios and work in all weather
