Meteorology: How Clouds Form

Professional Development Web Seminar: Meteorology--How Clouds Form

NES and NSTA are hosting a free 90-minute Web seminar on March 14, at 7:30 p.m. EDT. Learn about the relationships between air pressure, temperature, volume and cloud formation. Get an overview of the necessary conditions for cloud formation and then see how to make a cloud in a bottle. Information will be provided about an extension activity, the S'COOL Project, which involves student participation in authentic science.

This is the last time this seminar will be offered during the current school year.

April is the Cruelest Month - NASA Science One year after the historic tornado outbreak of April 27-28, 2011, researchers say they've learned a few things about deadly twisters. Today's story from Science@NASA presents some of the scientific findings that emerged from the swath of destruction.

The energy entering, reflected, absorbed, and emitted by the Earth system are the components of the Earth's radiation budget. Based on the physics principle of conservation of energy, this radiation budget represents the accounting of the balance between incoming radiation, which is almost entirely solar radiation, and outgoing radiation, which is partly reflected solar radiation and partly radiation emitted from the Earth system, including the atmosphere. A budget that's out of balance can cause the temperature of the atmosphere to increase or decrease and eventually affect our climate.

NASA's Aqua Satellite Sees Small New Tropical Storm Near Tonga

Tropical Storm 11P has formed in the South Pacific Ocean, and NASA's Aqua satellite captured an infrared image of its cloud temperatures, revealing power in the cyclone.

S'COOL: Why do we observe clouds?
Clouds are powerful agents of global change. They affect the overall temperature or energy balance of the Earth and play a large role in controlling the planet's long-term climate.

To understand the impact of clouds over time, satellites measure the planet's clouds and energy from space. Data from NASA's ERBE and CERES satellite instruments, for example, have made and continue to make significant contributions to the understanding of clouds. TERRA spacecraft

Making sure satellite instruments are accurate is very important. So, scientists also study clouds and the Earth's energy from instruments on aircraft and ground stations. This process is called validation. You can view a Webcast on the validation of the Aqua spacecraft (Quicktime; 14 MB).

Measurements from these experiments test the accuracy of satellite instruments. Cloud observations made by people, such as S'COOL participants, are also an important part of this ground truth exercise.

Amanda Blough’s fourth grade students joined the NASA S'COOL project and submitted several ground observations of the clouds. They will continue to do this throughout the year as an ongoing project. This activity was introduced right before they started the lesson on clouds. It was a great introduction to clouds and it got the students outside and learning how to make scientific observations that will be used by NASA scientists. This activity was nicely paired with the NASA Now video about the A-train as well as with the NPP Launch. The students were very aware of the many satellites that orbit the earth and their many functions.

The S’COOL observations are timed to contribute to the validation of the CERES satellite instruments, by collecting ground observer reports of cloud type, amount, etc. The S’COOL team would like your help with an Intensive Observation Campaign to contribute to the initial validation of this new CERES instrument. By participating in this campaign, you and your students have the opportunity to engage in real science that will help NASA. This campaign will take place during the month of December, which is expected to be the first month of operation of the instruments on NPP, following completion of the on-orbit instrument checkout.

Officials Hail NPP Satellite Launch

10.28.2011 - NASA and NOAA officials congratulated each other this morning following the successful launch of the NPP spacecraft aboard a Delta II rocket from Vandenberg Air Force Base, Calif. Ken Schwer, NPP Project Manager, led off a news conference this morning about three hours after liftoff. He will be part of the team who will get the spacecraft checked out during the next several weeks so it can begin its Earth observing mission.

"Now the future of NPP starts and we look forward to NPP touching the rest of the world," Schwer said.

The NPP spacecraft was launched on-time at 5:48 a.m. EDT
