Project

SAPIENTIAM

Goal: The Paris Agreement has set out a global framework to limit the possibility of dangerous climate change. To this end, it is committed to holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels. The EU-funded SAPIENTIAM project will identify new mechanisms that will help describe the pre-industrial atmospheric status and its change as a consequence of emissions caused by human activities related to industrialisation. Specifically, it will carry out a laboratory experiment to simulate a pre-industrial-like environment’s atmosphere, adding to it the biogenic emissions, followed by anthropogenic emissions such as nitrogen oxides (NOx).

February 2021. Short (2 hours) NO injection (5 ppb) in chamber. After about one hour we initiated to measure a significant increase in ONs measurements.

January 2021. Organic nitrates measurements by TD-LIF in pristine like environment (low NOx regime).
 
Eleonora Aruffo
added an update
December 2020. TD-LIF setting has been changed to measure the gas and particle partitioning and the speciation of the organic nitrates. The inlet has been splitted: 1) Bypass line for gas+particle measurements; 2) charcoal denuder line to remove the gas phase and measure the particle phase of organic nitrates.

September 2020. The TD-LIF instrument, developed at Prof. Piero Di Carlo's laboratory of Atmospheric Physics and Chemistry, has been successfully installed in the Prof. Martin's laboratory and integrated in the Harvard Environment Chamber setup.

HEC experiments varying the NOx concentration in chamber. Master Chemical Mechanism on a Mathematica-based model has been ran to estimated the RO2 fates as function of different NO injection in chamber.
Harvard Environment Chamber (HEC) setting to simulate a pristine like environment.
