Do you want to learn how to take surface temperature observations? The students at the Toledo Public School Natural Science Technology Center (NSTC) show how it can be done in this short video.  https://www.facebook.com/globemissionearth/videos/2581539525466417/ December is the second month of Urban Heat Island Effect Research Campaign. Take as many observations in the month of December as you can. Take observations from two different sites such as asphalt, concrete, grass or shrubs. There was great participation since October. Surface temperature observations were ...

Thirty-one seniors armed with the GLOBE Observer mobile app hiked Kamanaumui Valley at the end of October. During the 3.3 mile trek, hikers made Land Cover and Mosquito Habitat observations, while passing verdant tropical vegetation, the ruins of a colonial manor, a biological restoration plot and ancient petroglyphs.  OLLI trekkers used the GLOBE Observer app to make observations The Osher Lifelong Learning Institute (OLLI), University of Hawaii at Manoa offers a wide range of educational activities and non-credit courses for people 50 years and older. GLOBE Observer ...

The GLOBE Fall Cloud Observation Challenge brought in more than 45,000 observations from citizen scientists in more than 17,000 locations in 93 countries on every continent — including Antarctica. This influx of cloud observations is super helpful to NASA scientists who work with geostationary satellites and the suite of satellite instruments known as the Clouds and the Earth's Energy Radiant System (CERES). By comparing geostationary and CERES observations from a particular area to data submitted by citizen scientists, scientists can differentiate between wispy cirrus clouds and ...

As the GIO announced a call for nominations for GLOBE working groups, where i happen to have served for the period 2016 - 2019, my seniors at the University asked members of faculty,  to demonstrate how we have contributed towards SDGs for the last 2 years? Suprisingly its the small things i have been doing in GLOBE which have given me mileage over my colleagues. Having been a member of GLOBE since 2006, and serving in different capapcities while being active in GLOBE campaigns and working groups, has made me contribute to SDGs [ 4, 5, 15, 17]. My personal research has enabled me ...

    Guest Scientist blog by Dr. Joseph Kerski, Esri Esri and the GLOBE program have been working together on initiatives and educator training for decades.  GLOBE was one of the first major education-focused citizen science programs, and it offers a wealth of data on soil chemistry, water quality, weather, and much more, as well as rigorously tested methods to have your students collect and contribute data, and a network of educators with which to collaborate. Using GLOBE Observer Mosquito Habitat Mapper data as an example,  we look at what I consider to ...

We are kicking off the Urban Heat Island Effect campaign today with a heat wave in the eastern United States. Many record temperatures were broken today with highs reaching 32 to 35 C. 53 sites around the world entered data already today, October 1, 2019. You can see that most of the observations were in places of the world where it has been pretty warm. The coolest observation came from Alaska. My students, Shefa and Ahmad, took surface temperature observations of a grassy field in front of my building at the University of Toledo and then of the parking lot behind the building. ...

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 ...

Guest Scientist Blog by Kayla M. Thomas, McNair Scholar, Southern Nazarene University Oklahoma has experienced three major outbreaks of West Nile Virus (WNV) since its local introduction in 2002. State and local health agencies provide surveillance of mosquito-borne diseases although reduced resources and personnel limits its scope. With the addition of citizen scientists from the greater Oklahoma City, I was able to analyze ongoing mosquito observations by using NASA’s GLOBE Observer mobile app during the 2019 mosquito season. Citizen scientist participation studies have ...

Guest Scientist Blog by Kenan Arica, NASA JPL Summer Intern Mosquitoes are vectors for diseases such as malaria, dengue, Zika, Rift Valley fever, West Nile virus, chikungunya and other diseases. Unfortunately, climate change is expected to make the spread of mosquito-borne diseases worse. This summer, I did some exploratory research to see if we could combine the power of GLOBE citizen science data and social media to learn about where mosquitoes are found.     This summer I worked with the GLOBE Observer Mosquito Habitat Mapper (MHM) data. To ensure we get the ...

Guest Scientist Blog by Jacqueline Castellanos, NASA JPL Summer Intern My summer internship at NASA Jet Propulsion Laboratory exposed me to all parts of the scientific process. I went on a hike in search of mosquitoes, collected data, and I had the opportunity to teach teachers how to use the GLOBE Observer Mosquito Habitat Mapper. In my analysis, I learned how to work with data of varying quality and saw how environmental factors affect mosquito abundance. Most importantly, I learned that data given context and explored in meaningful ways can help us understand the problems we ...

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 ...
