Hello, GLOBE Family! You may be familiar with my dichotomous cloud key !  I am a meteorologist and educator who is interested in better understanding students ideas of weather and climate related topics. Would you help me launch an international research study to compare students' understanding around the WORLD and around different climate zones? How well can our students differentiate between WEATHER and CLIMATE and how well do they understand the complex ideas of CLIMATE CHANGE. Would you be willing to have your students take 20 minutes to complete ...

As you may know, the NASA Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) will launch on September 15, 2018 from the Vandenberg Air Force Base in California, USA. The ICESat-2 satellite will use an on-board laser altimeter system to measure the height of Earth. Measurements of ice sheets, sea ice, bodies of water, mountains are all part of what ICESat-2 will measure. For our collaboration with The GLOBE Program, we want to focus on one exciting variable that the ICESat-2 satellite will measure, TREE HEIGHT! GLOBE has several ways to measure tree height. You can find them ...

As spring begins here in the northern hemisphere, we often see seasonal changes in our precipitation patterns. As most of you know, heavy rains can result in the mass movement of land- known as "landslides".  These natural hazards occur all over the world, and often result in destruction of property and even death. Scientists at NASA's Goddard Space Flight Center are in the process of building an open worldwide database for landslide research- and we need you to help us out! Learn about the " Landslide Reporter " citizen science program in this blog .  Learn more about ...

The GLOBE Program is in a unique position to provide citizens worldwide with amazing benefits. One of the biggest benefits, I feel, it that of gaining a larger perspective. I work at Goddard Space Flight Center with the GPM (Global Precipitation Measurement) mission . This Earth-observing satellite is able to measure global precipitation and update these measurements every 30 minutes. You can see the latest data animation for the past week here . As NASA is a key sponsor of The GLOBE Program, many of us who work for NASA are able to share the unique perspectives that ...

Right now I am sitting in my home office, watching the trees bend as the wind howls. My automated weather station in my front yard has an anemometer that is simply going nuts, and the wind vane is wildly careening back and forth as the winds pushes in from all directions. We have had wind gusts that exceeded 40 mph and now my weather station is reporting sustained winds at 25 mph.  The power of nature simply astounds me and fills me with wonder and awe. Being able to make visible observations of the impact of the wind- by watching how fast the clouds are moving, seeing the ...

We have all been dismayed to see the extent of the damage done during the recent landslides that occurred after forest fires had destroyed much of the vegetation, and then intense rain caused a horrific landslide to occur in Montecito. You can read more here about how NASA's Operational Land Imager (OLI) on Landsat 8 was able to acquire natural color imagery of the affected region both before and after the landslide occurred, which enables us to observe the impact of this natural disaster on the environment. NASA's Global Precipitation Measurement mission (GPM) measured the ...

Satellites can detect and collect a lot of observations in very short amount of time. It is simple to think that anything that is white in an image is a cloud. Well, not always.  Look at these beautiful images taken by the GOES 16 satellite of the recent "Winter Weather Bomb" that left a blanket of snow from South Georgia to New England on January 4, 2018. Click here and watch a loop of images from the GOES 16 satellite for January 4, 2018. GOES 16 Image taken on January 4, 2018 at 171720Z GOES 16 Image taken on January 4, 2018 at 201720Z   ...

  It turns out that we are most likely entering another mild La Niña winter across the globe. This article, “ La Nina Makes a Quiet Return ”, describes how scientists are able to use data on sea surface temperatures from were made by altimeters on the  Jason-2  and  Jason-3  satellites, and show averaged  sea surface height  anomalies. Climatologists are predicting that this La Niña should last through the 2017-2018 winter period in the northern hemisphere, and then should change back to neutral conditions by late spring. Be sure to become a ...

Too much water can have devastating consequences when it falls too quickly on Earth's surface. On January 9th, the " Water in Our Environment " webinar will spotlight the experiences of our GLOBE community in Asia and the Pacific.  Earlier this week in the Philippines, tropical cyclone Kai-Tak wrecked havoc on this region as it caused extreme flooding and landslides . On December 4th and 5th, tropical cyclone Ockhi was the strongest cyclone to develop in the Arabian Sea since 2015, and it brought intense rainfall to the western part of India. A recent CNN report stated ...

Sometimes, actually most of the time, I forget to be grateful for the fact that I have easy access to clean freshwater. When Thanksgiving rolls around each year, I try to step back and consider the many things I have to be thankful for. Day after day I work with the amazing science team behind the Global Precipitation Measurement mission, and I never cease to be completely amazed at how technology has enabled us to monitor our home planet.  During our last ENSO Phase III webinar, we learned about water quality in Europe from several GLOBE scientists, teachers, and students ...

Many of us are so used to having clean freshwater that is easily accessible that we don't often stop to marvel at the fact that we are incredibly fortunate. The majority of our freshwater comes from our water cycle, and precipitation is unevenly distributed across the globe. You can learn more about the importance of clean freshwater resources in this "one-pager" entitled " Precious Freshness ".   During our ENSO Phase III Webinar #3, we will be focusing on water quality in Europe and Eurasia. We will host this webinar at 18:30 UCT, and hope we will have many of you from ...

One way to teach students about water quality and/or how scientists go about their work is to share articles with them. Here is a great article entitled " Study Maps Hidden Water Pollution in U.S. Coastal Areas ". This research shows a great example of the use of both NASA satellite data and ground-based data. In this study, the researchers used U.S. topographic data as well as NASA climate models to "identify key inland regions that contribute groundwater and contaminants to the coast. They examined rainfall, evaporation rates and the amount of known surface runoff to ...

It is pretty neat when you can get two for the price of one- as most teachers can attest to with regard to trying to get everything into their curriculum. Did you know that this year, the FIRST LEGO League's challenge is focused on water. And what could be better, as that water is also the theme of this year's ENSO Student Research Campaign !  The LEGO Challenge Project states: "People use water every day, but they don’t think much about how and why they use water. Whether it’s directly (drinking or washing) or indirectly (manufacturing the products they use or producing food ...
