IUP Work Packages (WP)

IUP will focus on the retrieval of aerosol particle size information and extinction profiles from satellite limb-scatter observations. It will also perform an assessment of all observational data together with UG and exploit the synergies between observations and modelling.

» WP 1: Analysis of satellite limb observations for characterizing the variability in stratospheric aerosol extinction and particle size distribution

Aerosol particle size distribution from SCIAMACHY limb measurements

Aerosol extinction coefficient profile retrieval from OMPS-LP measurements and feasibility study with respect to the aerosol particle size information

Using SAGE III/ISS limb-scatter measurements to characterize the stratospheric aerosols

» WP 2: Measurement data assessment

Measurement data analysis.

» WP 3: Estimate the dependence of optical properties and radiative forcing of volcanic aerosols on the approaches to construct datasets to assess uncertainties

Comparison of observed and modelled aerosol extinction, optical depth and aerosol size distribution.

» WP 4: Improve the understanding of effects of volcanic eruptions on stratospheric water vapour

Assessment of satellite H2O observations

Research highlights

Angstrom exponent on mode radius dependency
Dependence of the Ångström exponent (α750/1530) on mode radius, Rmod, and absolute distribution width, w (panel (a)). In panel (b) α750/1530 as a function of median radius, rmed, and σ is presented. Plot is based on the SCIAMACHY limb data in the tropics (20ºN - 20ºS).
omps_kel_calb_lat_t
Evolution of the aerosol extinction coefficient at 869 nm at different altitudes during Kelut eruptions, based on the 10-day averaged IUP V1.0.9 OMPS-LP product.
