Monitoring atmospheric ammonia with satellite and on-field gas sensor array measurement techniques

The purpose of this research is evaluating the potential of different gas sensor arrays for small scale, in-situ atmospheric ammonia detection, to counterbalance the shortcomings of satellite atmospheric ammonia detection. In order to achieve this, one drone-based and 20 ground-based ammonia gas sensor arrays will be developed, aiming for the highest sensitivity & selectivity possible, amongst other important sensor characteristics. It is important to note that atmospheric ammonia concentration can differ significantly as a function of regionality and time. As a result, different types of ammonia gas sensors will be tested in both controlled laboratory and in-situ environments, in order to develop the best suited gas sensor arrays with high sensitivity & selectivity for ammonia, besides ensuring atmospheric ammonia detection over a large range of concentrations.
