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 ...

  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 ...

Currently, Science education has transitioned away from textbooks to more hands on learning. This is an amazing opportunity for teachers to move away from the normal lecturing and explaining in class to reshaping the process of learning. I think that the GLOBE Program is a fantastic organization and empowered program that promises to give an essential change in education.  One example is teaching and learning from directs activities in the field. An excellent activity is to share data from school to school through collaboration.  Students can share what  they are ...

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 ...

What are the impacts of extreme events, like Hurricane Harvey, on the water quality? This article from the Smithsonian magazine describes multiple ways in which public health officials are responding to several threats facing residents of Houston and surrounding locations. These threats include the impact of mold, the potential of an increase in vector-borne diseases such as Zika and West Nile virus, and the problems of contaminants left behind in the public water supply.  Have you experienced severe flooding in your region that resulted in problems with water quality?  ...

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 ...

From the start, the measurement of daily maximum and minimum air temperature within one hour of local solar noon has been a key GLOBE protocol. The low cost approach was to use a U-tube thermometer housed in a wooden instrument shelter facing away from the equator. The U-shaped tube contained mercury with pins on either side of the mercury. As the air temperature warmed the pin on one side would move while the other pin stayed in place; when the air cooled, the pin on the other side would be pushed up. The pins were held in place by magnetized strips behind the thermometer tube so that ...

In my previous blog post, I showed the results of my surface temperature experiment. It was a great way to highlight some of the practical ways to use science, and it was yet another way for me to talk about my puppy. My experiment and accompanying blog was straightforward enough. I identified a problem, I designed an experiment, collected data, and presented the results. This is how science is done, right?! With years of experiment experience behind me, this should have been a very fast and easy task, but I had one problem that I forgot to account for, my Attention Deficit Disorder. ...

As Earth science has a single uncontrolled object of study, the first rule is to take today’s data today. While ice and sediment cores and fossils can reveal past conditions, the observations that can be made right now cannot be replaced by ones taken later. This goes well with the Native American adage, “You can’t step in the same river twice.” The environment is constantly changing and doing so on a wide range of time and space scales. In a recent video post, Neil deGrasse Tyson said, “One of the great things about science is that it is an entire exercise finding what is true. You ...

Just when you think that perhaps the weather systems are settling down- our amazing scientific instruments are able to detect a potential change! I never cease to be amazed at what we are able to learn about Earth's systems- both from the ground and from space!  This article from the New York Times just came across my newsfeed- " It's Like it Never Left: Another El Nino May be on the Way ". In the article, it states that " Among the potential effects are wetter conditions across the southern United States, including Southern California; a drier Midwest; and drought in ...
