The Atmospheric Composition Group of the Earth Sciences Department (Barcelona Supercomputing Center – Centro Nacional de Supercomputación, Barcelona, Spain) offers 2 PhD positions in:

1.    Aerosol effects upon climate (Supervisor: Dr.Carlos Pérez García-Pando)
Research Project Description:
Atmospheric aerosols are a key component of the Earth System and their multiple effects upon climate remain nowadays poorly constrained. Mineral dust, the most abundant aerosol by mass, plays a major role in different aspects of weather, climate and atmospheric chemistry. It is unique among aerosol phenomena, as it is both an indicator of past climate variations and an integral contributor to climate change. Dust perturbs the energy and water cycles of the atmosphere by direct radiative forcing and by altering cloud evolution. Dust particles interact with other gas-phase and aerosol components, influencing their mass in the atmosphere. Dust also delivers iron and phosphorus to land and ocean ecosystems, increasing photosynthesis, while reducing the atmospheric concentration of carbon dioxide. These effects are highly dependent on the physical and chemical properties of dust particles, hence in their composition, which is either not accounted for or poorly constrained in Earth System models. 

This project focuses on two aspects: (1) constraining the regional variations of dust mineral composition in state-of-the-art models, considering up-to-date soil mineralogical databases and extending current theoretical frameworks, and (2) reducing uncertainties in dust radiative forcing and/or soluble iron deposition, both of which fundamentally depend on the dust mineral composition

2.    Allergological pollen modelling for air quality forecasts (Supervisor: Dr.Oriol Jorba Casellas)
Research Project Description:
Pollen allergy has a remarkable clinical impact all over Europe, and there is a body of evidence suggesting that the prevalence of respiratory allergic reactions induced by pollens in Europe has been on the increase in the past decades. The allergenic content of the atmosphere varies according to climate, geography and vegetation. Europe is a geographically complex continent with a widely diverse climate and a wide spectrum of vegetation. Consequently, pollen calendars differ from one area to another. In northern Europe, pollen from species of the family Betulaceae is a major cause of the disorder. In contrast, Mediterranean areas spectrum shows higher diversity of pollen types most of which that are rarely found in central and northern areas of the continent

In this context, the aim of this project is to develop an aerobiological module in the air quality forecasting system CALIOPE to better forecast aerobiological concentrations in the air in the European level, but with special emphasis on the Mediterranean areas and Spain.

Deadline for applications is 1st January 2018.
