Breogán is improving land surface data assimilation at MetOffice.
Breogán is working in the Earth System Data Assimilation group improving SURF that is used to provide accurate temperature and soil moisture values for the global and limited area models of the Unified Model operational set-ups.
Breogán gained a BSc in Physics in 2002 at the University of Santiago de Compostela, followed by a MSc in Non-Linear Physics in 2004.
In 2002 he started to work in various topics related with operational numerical weather forecast at MeteoGalicia, with particular emphasis in ensemble forecasting.
From 2009 to 2010 he worked on the Data Assimilation Department at DWD on assimilating radiance data with the LETKF scheme, with a focus on the localisation.
In 2010 he returned to MeteoGalicia, where he was promoted to manager of Numerical Prediction soon after. There he was responsible for managing the developments related with atmospheric, waves and hydrodynamic operational forecasting, with a strong focus on high resolution modelling and end-user needs.
In 2015 he joined the MetOffice to work in the Earth System Data Assimilation group to work on SURF, focused on improving its application to regional modelling.
Also, in 2013, while working in MeteoGalicia, Breogán resumed his PhD studies, with two mayor lines of work. As part of this, he is evaluating the impact of spectral nudging on limited area models and its suitability as data assimilation technique. He is also studying the effect of the water table dynamics on seasonal climate.
