Hi,
The ESA Living Planet Symposium will take place on 23-27 May in Bonn,
Germany. There are at least two sessions related to ARTS. Please see below.

*A1.10 Cloud and Precipitation Optical Properties and Microphysics*
Open Session
Description:
Remote sensing of clouds and retrieval of their ice and liquid water
content requires a good knowledge of cloud microphysics and
corresponding optical properties. With new space-borne sensors and
synergistic retrieval approaches using cloud observations at very
different wavelengths comes the need for improved knowledge of cloud
microphysics and the related optical properties of ice and liquid
particles, including precipitation, at wavelengths reaching from the UV
over the visible and infrared into the microwave. Within the retrieval
process of cloud properties from remote sensing data, a forward model
must use suitable (bulk) microphysical assumptions and scattering
assumptions at each wavelength. For multi-wavelength retrievals these
assumptions must be consistent in order to allow correct convergence of
the minimization procedure. A key additional challenge for retrievals is
how to interpret observations of atmospheric profiles containing more
than one cloud/precipitation type. Examples include mixed-phase layer
clouds, and deep precipitating clouds containing snow, melting ice and
rain. Progress in this area could require the synergy of different
instruments, and/or improved prior constraints and insights based on
field campaigns. This session addresses cloud (bulk) microphysics and
optical properties over the UV to MW spectrum, their application and
required inputs from in-situ and laboratory observations.
Convenors: Tobias Wehr (ESA), Anthony Baran (Met Office), Patrick
Eriksson (Chalmers University), Tiziano Maestri (University of Bologna),

*A1.09 EarthCARE: Preparing for the Scientific Mission Exploitation to
Quantify the Impact of Clouds and Aerosols on Radiation*
Open Session
Description:
The EarthCARE mission, prepared in cooperation with JAXA for launch in
2023, will provide unprecedented high-quality data set of global aerosol
profiles, profiles of ice water and liquid water clouds, cloud particle
vertical velocities and precipitation information together with
broad-band radiation measurements and derived atmospheric heating
profiles. These data will allow a broad range of scientific research of
quantifying the role clouds and aerosols in radiation and atmospheric
heating and cooling, cloud processes and cloud-aerosol interaction. The
near-real time availability will enable the exploitation of the data for
numerical weather prediction. This session will present the preparation
of research which EarthCARE will bring to the next level, which is
presently being performed with, for example, A-Train data, ground- and
airborne systems and models.
Convenors: Tobias Wehr (ESA), Anthony J. Illingworth (University of
Reading), Ulla Wandinger (TROPOS), Nicolas Clerbaux (RMIB), Jürgen
Fischer (Free University of Berlin), Dave Donovan (KNMI)
