§ You will be welcomed in a INRAE research unit and supervised by a small team of ICOS lead scientists from France (INRAE), Italy and Belgium among others. The research project aim at evidencing the putative impacts of the Spring 2020 pollution reduction on the CO2, H2O and energy exchanges from terrestrial ecosystems. Collaborating with ICOS scientists, you will undertake a 2-dimensional analysis of half hourly values of atmospheric flux data: (1) between stations exposed to different levels of pollution and (2) a time series analysis along a 5 –year long time series from 2015 to 2020. Ancillary data will be obtained from Copernicus and MODIS projects as well as complementary in situ networks (ICP-Forest, Fluxnet) and data sources (WMO, EMEP). The flux data requested are already collected by the ICOS Ecosystem Thematic Centre and the project is mainly dedicated to data analysis per se.
§ You will be in charge of:
– From the ensemble of data already collected, control the quality and relevance of the data sets
– Gather additional data concerning the Ozone and Nitrogen deposition, diffuse / direct light ratio and spectral data from Copernicus and Modis projects.
– Using statistical and IA methods, test different hypothesis regarding the impacts of the COVID lockdown and ecosystem-atmosphere flux through synchronic and diachronic comparisons.
– Assumption to be analysed concerns the effects of a putative modification in the light regime, NOx, NHx and Ox depositions on ecosystem atmosphere exchanges of radiation, sensible and latent heat and carbon dioxide.
– Publishing and communicating your results in international scientific journals and e.g. at Geophysical Unions Assemblies (AGU, EGU).
