Tú puedes reportar el cielo como 100% cubierto u obscurecido usando el protocolo de nubes en GLOBE y en la aplicación GLOBE Observer. ¿Cuál es la diferencia? Este blog tiene consejos para ayudarte. Todas las fotografías en este blog fueron colectadas por observadores como tú. ¡Gracias! Al principio encontré la diferencia entre cubierto y obscurecido algo confuso, pero cuando entendí el significado de ambas, pude mejorar mis observaciones. Empecemos con definir ambos términos:   Cubierto – Noventa por ciento o más del cielo está cubierto por nubes. En esta situación ...

In the GLOBE Clouds protocol and GLOBE Observer app, you can report if your sky is “overcast” or “obscured”. But what’s the difference? Below are some tips to help! All the photographs featured were collected by observers just like you - Thank you! I found “obscured” and “overcast” very confusing at first, but when I understood what they meant, things made much more sense. Let’s start by defining them: Overcast – The sky is completely covered by clouds (cloud cover greater than 90%). This means that you will see little or no blue sky. When it’s overcast, you are looking at ...

In GLOBE, there are two major perspectives on the global environment – the spheres and the Earth system. The Teacher’s Guide and the new sphere pages build on the approach that examines Earth as the atmosphere, hydrosphere, biosphere, and pedosphere. The study of Earth System Science focuses on the cycles that connect the spheres – the Energy, Water, and Biogeochemical. The Honor Roll provides recognition of those who report in depth in one area or another. There are three honor rolls recognizing Atmosphere measurement reporting; one for Hydrosphere;, and two each for Biosphere and ...

I just updated HoloGLOBE to v1.0.2. For those of you new to this app, HoloGLOBE brings NASA and NOAA visualizations of the Earth to the palm of your hand through augmented reality (AR). You can read more about the app here: http://www.palmyracove.org/InstituteforEarthObservations/HoloGLOBE.aspx In this latest release, I have added play/pause functionality to the MyNASAData module. The MyNASAData is essentially an augmented reality version of GLOBE's Earth System Poster. In addition the new ICESat-2 module has been added. The ICESat-2 module was built by Emme Wiederhold, a ...

Eight-grade students from Our Lady of Mount Carmel School have been very active during our GLOBE 2017-18 U.S. Air Quality Student Research Campaign. In fact, they recently submitted their team projects to the GLOBE 2018 International Virtual Science Symposium. All students have done remarkable work and one of the most important skills they have developed is collaboration. Among these students, one of them stood out for becoming a Calitoo expert user and for helping not only the members of her own team, but also the members of all other teams, with her accurate AOT measurements. This ...

Spring is starting to spring in some parts of the Northern Hemisphere but not quite yet in others. The March observations period for the Urban Heat Island/Surface Temperature Student Research Campaign has started. Please take surface temperature observations in March to help out with the campaign. If you can, please take observations from two sites so you can compare the temperatures for them. One approach is to take observations from a grassy area and an asphalt area to compare. Just a quick look at surface temperature data on the GLOBE visualization page shows the cold weather that ...

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. ...

These are the results from my surface temperature experiment that I discussed in my previous blog post (same title, part 1). Results and Conclusion : Figure 2: Graph of average surface temperatures of the three surfaces over three days including air temperature data lines. My results show that my hypothesis was half right (remember, it’s ok if your data results do not match your hypothesis!). During the day, asphalt was the hottest, concrete was in the middle, and grass was the coolest. The surface temperatures of all three dropped at night, however, I was ...

In case you missed it, last month, was all about the 2017 International Virtual Science Symposium . There were over 140 entries from all 6 GLOBE regions. Students submitted reports about their research on all of the “spheres” (hydrosphere, atmosphere, biosphere, pedosphere, and earth as a system) and they were reviewed by a panel of scientists, teachers, and science enthusiasts to be rewarded with stars and badges. I had the wonderful privilege of being able to read through and review several projects. I was blown away with the thought and hard work that went into these ...

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 ...
