    Citizen Science, Imagery

    Classifying the sky’s color is one way to indicate the level of aerosol loading in the atmosphere. Citizen scientist can help in this effort by recording the color consistently so it can be used for analysis. Create a tool that lets people record the color of the sky using consistent and qualitative standards at a specific location. The tool can compare results to the nearest data from Aeronet (AErosol RObotic NETwork) or similar sources, which could be used to improve the accuracy of these networks.


    Sky color is a way to provide a qualitative indication of aerosol loading in the atmosphere. It is an accessible way for students and others to observe the environment, but the observations could benefit from a more quantitative way to record the information. People can gather sky color data in a consistent manner (there is at least one sky color and visibility protocol) and compare it to the level of aerosols from air quality monitors.

    Solution Ideas

    Here are some ways for you to frame this solution:

    Develop a method to use a smartphone camera to quantitatively assess sky color using sky color protocols; pull in the nearest Aeronet (or similar) data; present the sky color and Aeronet information together for further analysis; and allow users to compare the data from a single location in different times and locations.

    Sample Resources

  • The following projects are solving this challenge:

    • Social Sky Color

      Create a simple HTML5 app to take the pictures, geo tag them and submit to the server with extra information. On the server side receive the files with data, categorize them, store them. Also allow website visitors to browse them by time and location. We will have - PhoneGap based mobile ap... Visit Project

    • SkyCorpus

      SkyCorpus - it's an uniform database about the blue sky. The database contains the colour of the sky and clouds, the amount of clouds, brightness of the sky, and the actual data obtained from AERONET. Of course, all images are stored. These are not all the possible features, we can easily add ne... Visit Project

    • My Sky

      # My sky (Challenge My Sky Color) ## Overview The goal of this project is to involve as much people as possible for regulary making and uploading geotagged photos of the sky. Complete solution for collecting photos of the sky can be devided into the following parts 1. Mobile appl... Visit Project

    • SkyMetric

      The picture click of the sky from the app will give a clear observation of aerosol loading but the crowd-sourcing the data also help improve the service better. Proposed Solution: 1. Develop a method to use a smartphone camera to quantitatively assess sky color using sky color protocols; pull... Visit Project

    • AOT-calculation

      We have developed the method of measuring AOT by using smartphone. This method requares pair of photos and information about time and position. It may be used to create an application for environment monitoring. This method isn't demanding any tuning. And it isn't hard to using by consumer. Visit Project

    • Skynet

      Skynet is a crowdsourcing platform whose operations are almost exclusively performed by smartphone-toting humans, in service of its goal of furthering our understanding of air quality, aerosol loading, and our measurement of said. # The Concept Sky color is an indicator of air quality; spec...

    • SkySnapper

      Snap the skies clean with SkySnapper! ================================ The Problem -------------- The World Health Organisation estimates that [7 million deaths per year are linked to air pollution](, one in every eight deaths ... Visit Project

    • Sky Environment

      This is a crowdsourcing application. It can take picture of the sky and tell the sky color and the color and gps info gets uploaded to the server. Sky-Environment app will show the latest 10 sky color uploaded on the server with GPS location, date and time. Visit Project
