Participation FAQ's NASA GLOBE Cloud
Answer: First, choose how you wish to participate. If you are an educator, you should join GLOBE and become a Certified GLOBE Trained educator. You can find a workshop near you about clouds or do the eTraining on Clouds.
If you are a science enthusiast that wants to submit your observations, we recommend using the GLOBE Observer app. Training tutorials are available to help you use the app and collect cloud observations. Learn more about how to submit observations.
NOTE: You must be a in a country that is a GLOBE member to participate in the ways described above. If you notice you are not in a GLOBE country, you can still submit your observations to NASA using the S’COOL Roving Cloud Report.
Answer: The GLOBE program calls protocols the steps designed by scientists for students and the general public to collect environmental observations that can later be used by researchers in their investigations. The cloud protocol provides the steps used to determine type, cover, and opacity of clouds including contrail.
Answer: Training is available for educators and for science enthusiasts to understand the steps selected for the collection of data. For GLOBE educators, the training allows you to submit cloud observations with some added observations of the atmosphere. It also allows you to have student accounts. For enthusiasts, the training allows you to alter your profile on GLOBE Observer and gives you more confidence in your measurements. See question 1, ‘How can I participate and submit cloud observations?’ to learn more about the different training available.
Answer: Observations +/- 15 minutes of a satellite overpass allow for optimal comparison with satellite data. If you miss a satellite overpass time, you are still able to submit your observations. Find out the satellite overpass times for your area. Additional suggestions for observations frequency include daily within one hour of solar noon and in support of the ozone and aerosol measurements, both enhancing comparison ability with complimentary protocol data. If you cannot make daily observations it is okay, but daily observations with the satellite directly over your area are optimal.
Answer: A team at NASA Langley Research Center in Hampton, VA receives and compares your observations with data from satellites. The results are sent back to you in a personalized email from NASA with your satellite match table. Learn how to read and interpret your satellite match table as well as ways you can compare your data to satellite observations. The data is also archived and made available through GLOBE.
Answer: Answer coming soon.
Answer: Answer coming soon.
Answer: Answer coming soon.
Answer: The team at NASA Langley Research Center in Hampton, VA compares your observations with satellite data over your area at about +/- 15 minutes from your observation time. A satellite overpass is the time when a satellite is right over your area. Find out when a satellite used for the comparison will be over your area.
Answer: Yes!! All data that you take is valuable for The GLOBE Program and the NASA Partnership.
Answer: The team at NASA Langley Research Center in Hampton, VA compares your observations with satellite data over your area at about +/- 15 minutes from your observation time. The team then sends a personalized email to you for each satellite match. Learn how to read the satellite match table.
Answer: If you would like to stop receiving satellite match emails
Answer: Find tips and tricks on how to read and interpret your satellite match table. We encourage you to look and compare your observations to satellite data. Here are some suggestions on how to interpret the observations and tips on how to read the satellite images and use the information.
Answer: The team at NASA Langley Research Center has put together some tips and tricks for you to learn how to read the satellite images you receive in your satellite match table.
Answer: Satellites orbiting and studying the Earth give NASA and scientists around a big picture of what is going on and the role of clouds in Earth’s changing climate. Satellites only see the tops of clouds, where you can see the bottom of clouds. By putting these two vantage points together, we get a much more complete picture of clouds in the atmosphere.
Answer: Clouds affect the overall temperature or energy balance of the Earth and play a large role in controlling the planet’s long-term climate. Accurate data on clouds is necessary to understand the impact over time. Satellites orbiting and studying the Earth give NASA and scientists around the world information on what is happening over a vast area, a big picture of what is going on. This video on how clouds cool and warm our atmosphere expands on how the Energy Budget effects our planet.
The Earth's energy budget, also known as radiation budget, describes the various kinds and amounts of energy that enter and leave the Earth system. It includes both radiative components (light and heat), that can be measured by NASA CERES instrument for example, and other components like conduction, convection, and evaporation which also transport heat from Earth's surface. On average, and over the long term, there is a balance at the top of the atmosphere. The amount of energy coming in (from the Sun) is the same as the amount going out (from reflection of sunlight and from emission of heat). This energy balance determines the climate of the Earth. Our understanding of these flows will continue to evolve as scientists obtain longer and longer records using new and better instruments. .
