Background concentrations in Norway: Towards automated annual updates. NILU OR

Schneider, P.

A semi-automated technique was developed for performing annual updates of the dataset on background concentrations in Norway which was produced in previous years. The code is written in the Matlab programming language and large parts of the code base are included in the Appendix of this report.

The spatial component of the system was updated to include data from 2009 through 2011. Acquiring and preparing the input data for the spatial component still requires a relatively small amount of manual effort, however the majority of the remaining process has been automated to the largest extent possible, such that only the derivation of the emivariograms for the residual kriging step requires very brief interaction by an expert user.

The temporal component has been updated to version 8 of the European air quality database (AirBase), now including several additional years up to and including 2013. Entirely new anomaly matrices have been calculated from the updated data for all background stations in Norway.

Assuming that the availability and the format of the required input data remains unchanged, future annual updates of the system can be carried out within a very short time frame on the order of around 1-2 days.

Measurement of volcanic ash in Norwegian air space. WP 1.1 Evaluation of infrastructure for measurement of volcanic ash from ground air. NILU OR

Durant, A.; Tørseth, K.; Kristiansen, N.I.

Measurement techniques used for characterization of volcanic ash clouds have been evaluated specifically with regard to applicability and limitations. This report summarizes how future infrastructure investments in Norway will be able to provide additional information about volcanic ash clouds that can be used to inform operational aviation authorities. Three main recommendations are given.
