The openair project

The openair project started in 2008 with 3-year funding from the Natural Environment Research Council (NERC). The principal aim is to make available innovative data analysis techniques for air pollution data – or more generally atmospheric composition data. openair is an R package that is openly and freely available to anyone. Some of the capabilities of openair include:

  • Importing air quality data from UK and European sites
  • Wind and pollution roses, bivariate polar plots and Conditional Probability Function (CPF) plots
  • Sophisticated conditioning plots
  • Bivariate polar plots, with recent enhancements (see publications), clustering
  • Back trajectory analysis
  • Model evaluation

The project welcomes contributions from other researchers from around the world. The development site is hosted on GitHub where all the code and additional infromation is available (including a comprehensive user manual).
