Submit your photographs to GLOBE or GLOBE Observer, especially as we get ready to start the Fall Cloud Challenge: What's Up in Your Sky  (Oct 15 - Nov 15, 2019)! People around the world have been noticing purple skies at dawn and at dusk, calling it the Raikoke Sunsets  (see photographs submitted ). The purple color is because of  sulfurous gas...

NASA está solicitando tu ayuda para determinar “¿Qué ves en tu cielo?” El equipo NASA GLOBE nube quiere estudiar diferencias en nubes y aerosoles. La data colectada durante este reto del otoño en el hemisferio norte o primavera en el hemisferio sur  será comparada con los resultados obtenidos durante el reto de primavera del 2018. Puedes ayudar sometiendo observaciones de nubes, polvo atmosférico, calina, o humo (límite 10 por día) a GLOBE usando cualquiera de las opciones de entrada de datos, incluyendo la aplicación móvil GLOBE Observer. Los participantes GLOBE...

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 vez...

Audience : Everyone! (Students and teachers all grade levels, informal educators, and the general public) Dates : October 15, 2019 - November 15, 2019 Observations : Clouds and aerosols (dust storms, haze, smoke). Limit 10 per day. 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...

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...

  ¿Vives en un área que tiene tormentas de polvo atmosférico? Nos gustaría que fotografíes el evento y envíes tus fotos usando el app GLOBE Observer. ¿Ya has estado enviando datos sobre tormentas de polvo atmosférico? ¡MUCHAS GRACIAS! Ahora queremos que todos sepan que pueden enviar datos sobre estas tormentas con GLOBE Observer usando los siguientes pasos.   Conoce a los científicos Daniel Tong es un pronosticador de polvo atmosférico con el Programa Nacional de Capacidades de Pronóstico de Calidad del Aire de la NOAA y el Equipo de Ciencias...

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...

  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...

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.      See how your data...
