REGs - Researcher Excellence Grants
The Researcher Excellence Grant REG is funded and contracted directly by EURAMET, however the REG-Researcher will report to the JRP-Consortium in terms of tasking and progress.
REG1: Centre of Ecology and Hydrology
Dr. Christine Braban is an environmental scientist who leads the Atmospheric Composition group at NERC. Dr. Braban is an experienced project manager and coordinates the UK Eutrophying and Acidifying Atmospheric Pollutants monitoring project for Defra. She has a background in laboratory and field measurements relevant to atmospheric chemistry including ammonia metrology, aerosol flow tube kinetics experiments and trace gas detection methodologies.
Dr. Braban was involved in both the field measurements and modelling components of the NitroEurope project and the Defra funded Agroforestry systems for ammonia abatement. She helped analyse data from the large ammonia measurement technique intercomparison undertaken in 2008 (Bobrutzski et al.) and has made or managed ammonia measurements at background, agricultural and remote locations.
REG2: University of Helsinki
Dr. Olavi Vaittinen has a background in fundamental molecular spectroscopy. He has specialised in trace gas analysis of indoor air and human breath by applying laser and mass spectrometric methods.
Dr. Vaittinen has developed sensitive instruments based on different spectroscopic techniques such as cavity ringdown spectroscopy (CRDS). By using CRDS, he investigated adsorption/desorption phenomena of ammonia on different surface materials while operating as a REG in the EMRP project Metrology for chemical pollutants in air (MACPoll). In the framework of MetNH3, he will expand those studies and complement the investigations performed in WP1, in particular by studying the effect of water on the adsorption process of ammonia.
The research leading to these results has received funding from the European Union on the basis of Decision No 912/2009/EC. Last update: 10/04/2018
