Satellite observations and modelling of hydrogen cyanide in the Earth’s atmosphere

Share this
Hydrogen cyanide (HCN) is one of the most abundant cyanides present in the global atmosphere, and is a tracer of biomass burning, especially for peatland wildfires. In this work we present observations of HCN during the 2015 Indonesian peatland fires from the IASI (Infrared Atmospheric Sounding Interferometer) satellite instrument. We also investigate HCN variability using an updated version of the TOMCAT three-dimensional (3-D) chemical transport model (CTM), which is evaluated using HCN profiles measured by the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) and FTIR ground-based instruments in the NDACC (Network for the Detection of Atmospheric Composition Change) network. Here, we compare model simulations with the IASI measurements over Indonesia. View source
