Argumentation is an important practice whereas the scientist develops explanations using evidence and reasoning to explain observed phenomena.

The volume of data in a single file or file system can be described by a unit called a byte. However, data volumes can become very large when dealing with Earth satellite data. Below is a table to explain data volume units (Credit:  Roy Williams, Center for Advanced Computing Research at the California Institute of Technology).

Background information on sea level.

Hurricanes are the most powerful weather event on Earth. NASA’s expertise in space and scientific exploration contributes to essential services provided to the American people by other federal agencies, such as hurricane weather forecasting.

Background information on deforestation.

Let us introduce you to Katrina Laygo and Melissa Oguamanam from NASA’s Goddard Space Flight Center. Melissa and Katrina are the Center Leads for the DEVELOP Program’s Goddard location. NASA’s DEVELOP Program is a student-led research internship that focuses on using NASA Earth observations to address community concerns and public policy issues.

Earth is a system of systems.

Check out this interview, taken from the NASA Earth Science Week video, where Janel is interviewed about her experiences with the weather, as a child and now as a weather forecaster.

Every day, scientists at NASA work on creating better hurricanes on a computer screen. At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, a team of scientists spends its days incorporating millions of atmospheric observations. Sophisticated graphic tools and lines of computer code to create computer models simulating the weather and climate conditions responsible for hurricanes.
