Strong First study of Sentinel-3 SLSTR active fire detection and FRP retrieval: Night-time algorithm enhancements and global intercomparison to MODIS and VIIRS AF products

Xu, W., Wooster, M.J., He., J. and Zhang, T. Remote Sensing of Environment

➢  New SLSTR active fire detection and fire radiative power (FRP) retrieval algorithm for Sentinel-3 satellite

➢  Basis for operational SLSTR FRP products from EUMETSAT and ESA, available e.g. through Sentinel Data Hub.

➢  Cluster based approach implemented to cope with SLSTR spatial mis-registation between certain channels.

➢  Strong FRP agreement is found between SLSTR and MODIS views of fire clusters on a per-fire basis.

➢  SLSTR offers a capability to detect smaller (lower FRP) fires than MODIS.

Global impact of landscape fire emissions on surface level PM2.5 concentrations, air quality exposure and population mortality

Roberts, G. and Wooster, M.J., Atmospheric Environment

➢  143 countries have an average population weighted (PW) PM2.5 exceeding the WHO recommended annual 10 μg m−3 guideline.

➢  Globally, 44 million people exposed to ‘unhealthy’ air quality on an annual basis.

➢ Landscape fire emitted PM2.5 results in 677,745 premature deaths annually.

➢ Children under 5 years comprise 39% of this total.

Strong impacts of smoke polluted air demonstrated on the flight behaviour of the painted lady butterfly (Vanessa cardui L.)

Liu, Y., Wooster, M.J., Grosvenor, M.J., Lim, K.S., Francis, R.A. Ecological Enyomology

➢ A strongly negative and highly significant
linear correlation between flight speed and
PM2.5 concentration was also observed.
➢ the longer the butterflies were exposed to
the elevated PM2.5 concentrations the more
obviously their flight behaviour declined.

Top-Down Estimation of Particulate Matter Emissions from Extreme Tropical Peatland Fires Using Geostationary Satellite Fire Radiative Power Observations

Fisher, D., Wooster, M.J., Xu, W., Thomas, G., Lestari, P. Sensors

➢ A TPM Ce estimate of 16.8 ± 1.6 g·MJ−1.
➢ A single one of these most radiant
fires is responsible for almost 10% of the overall particulate matter released during the 2015 fire event, highlighting the importance of this fire type to overall emission totals.
