iLEAPS 2019 Flux and Chemistry of VOCs Workshop programme details

Updated: Apr 5, 2019

iLEAPS 2019 Flux and Chemistry of Volatile Organic Compounds - Technical Workshop


This workshop will bring together scientists at all levels to provide an informal platform to share results, approaches, and ideas in terms of the progress in rapid measurements of VOCs and comprehensive data analysis by the novel chemical ionization mass spectrometers.

The workshop will focus on:

Presentation of capabilities of new Time-of-Flight mass spectrometric advancements including PTR3, VOCUS.

Measurements of VOCs at broad temporal and spatial scales from variety of ecosystems, and in the lab.

Measurements of direct VOC fluxes by Eddy Covariance (selected compounds vs entire suite), including standardisation and best practice.

Automated approaches for embracing complexity – tools for peak fitting, compound identification, making sense of chemistry and fluxes, providing user forum to express challenges, and ways forward.

This workshop is being organised by iLEAPS and UKRI Centre for Ecology & Hydrology. The workshop is associated with and follows EGU Science Session “AS3.33/BG1.20 Volatile Organic Compounds in the Atmosphere: Sources, Sinks and Transformations”

Event Date:

Day 1. Friday, 12 April 8:15 – 3:45 pm

Day 2. Saturday, 13 April, 8:15 - 3:30 pm


Arcotel (near EGU venue), Wagramer Str. 83-85, 1220 Wien, Austria


How to apply: Application is only possible via the EventBrite portal at Spaces are limited.
