Description

This dataset accompanies the journal article entitled "The ozone radiative forcing of nitrogen oxide emissions from aviation can be estimated using a probabilistic approach.", currently under review, and contains:

1) The post-processed version of the original dataset that is available here [1]: https://data.4tu.nl/private_datasets/cLnjZscxOJDZnBSajrE0XxooMxJspT40byq4FVnq26A. 

The original dataset has been generated from several simulations performed with the ECHAM/MESSy Atmospheric Chemistry model (EMAC). The short-term impact on atmospheric ozone (O3) from aircraft nitrogen oxide (NOx) emissions is estimated for five regions (North America, Eurasia, South America, Africa and Australasia), three pressure altitudes (200, 250 and 300 hPa) and two seasons (July 1, 2014 representing the Northern summer and January 1, 2014 representing Northern winter) using three calculation methods: Eulerian tagging, Lagrangian tagging and perturbation. Each region has 28 points at which 0.5 Gg of NO are introduced in the form of a 15-min pulse emission. 

In our manuscript, we use the Lagrangian tagging dataset. We compute the global annual mean radiative forcing of O3 from NOx for each and every emission point, and plot them in Figure 1 (b). The mass curves of NOx and O3 for two emission points are also plotted using the original data in Figure 1 (c). 

2) Meteorological data, fllight path data from EUROCONTROL,  great circle data which are plotted in Figure 5 (b) of the manuscript. 

Please consult the README file for specific details regarding the data.
