Donal Murtagh has been professor in Global Environmental Measurements and Modelling since November 2000 when the position was created as part of Chalmers Environmental Initiative. Donal's research interests lie in how the earth's atmosphere function as a whole and how radiative, chemical and dynamical process interact to create the various phenomena that we observe. The tools that Donal uses are often satellite based since there is a need for a global view if we are to understand how the processes work together. The Odin satellite was launched in February 2001 and continues to deliver data. Donal has been involved in the project from the beginning as the Odin Aeronomy Mission Scientist with responsibility for the atmospheric observation programme.
