NASA is requesting your help to determine “What’s up in your Sky”. The GLOBE Clouds team wants to study differences in clouds and aerosols. The data collected during this fall challenge will be compared to results from the 2018 Spring Clouds Challenge. Help by submitting clouds, dust, haze or smoke observations (limit of 10 per day) to GLOBE using any of...
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 stratus...

The NASA GLOBE Clouds team is looking for members of the GLOBE International STEM Network (GISN) or any researcher that would be interested in publishing research (as lead or co-author) using the GLOBE Clouds data.
We are looking for researchers that are interested in:
Cryosphere that would be willing to use cloud observations over the Arctic/Antarctica.
Satellite validation studies with collocated observations, particularly those collected during GLOBE Clouds Data Challenge (March 15-April 15, 2018).
Natural hazards to explore possibilities of using the...
The 2019 GLOBE International Virtual Science Symposium important dates and rubrics are now available! The GLOBE Clouds team at NASA Langley Research Center would love to see you use cloud observations in your research!
Do you need some ideas? Here are a few. Also, don't forget about the blog on how to come up with a good research question.
K-2nd grade:
- What is the cloud type observed the most during Fall/Spring/Summer (choose one or a different period of time)?
- Which cloud type, nimbostratus or cumulonimbus, produces the most rain at our school? (choose a...
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 student at...
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...
Today we will get a closer at look at the values displayed on our Calitoo screen.
When you first turn on your Calitoo, you will get a screen like the following: note the serial number of your instrument will be displayed.
After the initial screen, your instrument will display basic information as shown on the following picture (Source: http://www.calitoo.fr/uploads/documents/en/usermanual_2016_en.pdf)
TIP: The temperature displayed by your Calitoo is actually the temperature inside the instrument.
When you...
The NASA GLOBE Clouds team recently presented a webinar the details of how your cloud observations are matched to satellite data. The webinar, recording found below, also focuses on the importance and quality of the observations, ways that the data can be used by scientists, and current work being done by the team at NASA Langley Research Center in Hampton, VA. The webinar also highlights newly processed data from the temperature and cloud observations reported for the Great North American Solar Eclipse on August 21, 2017.

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 is...
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 they...
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 incorrect about asphalt...
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 projects. Of...
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 have...
In most scientific research an important test is whether the results of an experiment can be repeated, typically repeated by another lab and research group. A result that cannot be confirmed in this way is generally viewed as invalid. This is a great test for controlled experiments where virtually identical experimental conditions may be achieved.
In Earth science research involving observations of the natural world, experimental conditions cannot be reproduced. For environmental research the standard must switch for repeatable to intercomparable – capable of being compared. Research...
Most trees obtain water through their massive root systems, but did you know that some trees can absorb water through their leaves as well? This ability is called foliar uptake. Scientists recently discovered that trees in cloud forests use foliar uptake to obtain water. A cloud forest is a forest that has persistent or seasonally persistent fog or low-level cloud cover. Cloud forests are usually in the tropics or subtropics, have evergreen trees (trees that don’t lose their leaves) and tend to have a lot of mosses and vegetation in the understory of the trees.
Cloud Forest located...

GLOBE’s Earth as a System investigation area cultivates students’ awareness of an intricate web of global connections. Similar to real world scientists, students explore life science concepts, learning that “organisms can only survive where their needs are met.” The Earth as a System investigation area encourages students to observe patterns and connections, such as through phenology. Phenology is the study of how living organisms respond to seasonal changes in their environment. Only through observing and measuring can we notice if changes are occurring and how they occur.
