Europe Aerosols Campaign

NEW! Aerosols Campaign was recently awarded by a GLOBE Star, congratulations!

Aerosols are tiny particles in our atmosphere and have an important impact on environment, they influence air quality and are link to climate change. Join GLOBE in understanding aerosols!

Join Chloe in tracking aerosols!

Learn about the aerosols from scientists, see how to use a sunphotometer and how your measurements are connected to satellites!








Aerosol Campaign for schools 2015/2016

Two intensive observation periods are planned:

Autumn 2015: October 12th to November 8th

NEW! Spring 2016: March 7th to May 27th

How to join...?

  1. Become a GLOBE school;

  2. Use the GLOBE Aerosol Protocol, Field Guide and Data Sheet as well as other learning materials;

  3. Get a sun photometer;

  4. Start investigation: make your observations on clear-sky days;

  5. Don't forget to upload data to the GLOBE website, not later than June 6th 2016;

  6. Analyze your observations and connect and exchange with other schools on your findings;

...and if you can´t measure AOT with a sunphotometer, you can still:


  • Try out simple experiments in your classroom on how solar radiation interacts with atmosphere and with aerosols, how clouds are formed


  • Click a picture or shoot a video on aerosols and upload it on your school profile on Tell us how you joined Chloe in learning more about aerosols!



What happens with the data?

All the student measurements you add to the website can be visualized and downloaded through GLOBE Vizualization Tool. Need help doing so? Read how to here.

  • Find an aerosol scientist in your country and ask her/him to assist you with analyzing the data.
  • See the results from the spring and fall campaigns in 2013.
  • Aerosols campaign in France - results spring 2014.


Validation of satellite data by using ground data collected by students

Satellite instruments such as the OMI intstrument on the Aura satellite, MODIS on the Terra and Aqua satellites, or instruments on board of the CALIPSO satellite, are used to monitor and investigate aerosols in the atmosphere. Satellite data always need validation ('check') with observations from the ground. This is called ground truthing. It is done with the help of professional instruments at special measurement sites, but GLOBE students can be very useful for this too.

In the past the help of GLOBE students has helped scientists at the KNMI write a scientific paper in the Journal of Geophysical Research. In this paper we showed that GLOBE sun photometer observations can be of help improving MODIS satellite observations of aerosols (in terms of the aerosol optical depth, AOD) over the Dutch and Belgium coast-line.
