** We apologize for multiple posting **
Dear Colleagues,
The next General Assembly of the European Geosciences Union will be held in Vienna, Austria, 3-8 May 2020.

We would like to draw your attention to session G5.2/AS5  Atmospheric and Environmental Monitoring with Space-Geodetic Techniques.
The description of the session is given below and it can also be found at https://meetingorganizer.copernicus.org/EGU2020/session/35338



We encourage you to participate in it by submitting abstracts.



Notice that the DEADLINE FOR ABSTRACT SUBMISSION IS 15 JANUARY 2020, 13:00



Do not hesitate to contact us directly if you have any questions.



We are looking forward to welcoming you in Vienna!



On behalf of the convenors of session G5.2, Rosa Pacione



Co-conveners: Gert Mulder, Maximilian Semmling, Norman Teferle, Henrik Vedel


Geodesy contributes to Atmospheric Science by providing some of the Essential Climate Variables of the Global Climate Observing System. Water vapor is under-sampled in the current meteorological and climate observing systems. Obtaining and exploiting more high-quality humidity observations is essential to weather forecasting and climate monitoring. The production, exploitation and evaluation of operational GNSS-Meteorology for weather forecasting is well established in Europe due to 20+ years of cooperation between the geodetic community and the national met services. Advancements in NWP models to improve forecasting of extreme precipitation require GNSS troposphere products with a higher resolution in space and shorter delivery times than are currently in use. Homogeneously reprocessed GNSS data have high potential for monitoring water vapor climatic trends and variability. With shortening orbit repeat periods, SAR measurements are a new source of information to improve NWP models. Using NWP data within real-time processing of GNSS observations can initialize PPP algorithms, shortening convergence times and improving positioning. GNSS signals can be used for L-band remote sensing when Earth-surface reflected signals are considered. GNSS-reflectometry contributes to environmental monitoring with estimates of soil moisture, snow depth, ocean wind speed, sea ice concentration and has the potential to be used to retrieve near-surface water vapor.
We welcome, but not limit, contributions on:

*Estimates of the neutral atmosphere using ground-based and space-based geodetic data, use of those estimates in weather forecasting and climate monitoring
*Multi-GNSS and multi-instruments approaches to retrieve and inter-compare tropospheric parameters
*Real-Time and reprocessed tropospheric products for now-casting, forecasting and climate
*Assimilation of GNSS tropospheric products in NWP and in climate reanalysis
*Production of SAR-based tropospheric parameters and use of them in NWP
*Methods for homogenization of long-term GNSS tropospheric products
*Studies of the delay properties of the GNSS signals for propagation experiments
*Usage of NWP data in GNSS data processing
*Techniques on retrieval of soil moisture from GNSS observations and of ground-atmosphere boundary interactions
*Estimates and methods using GNSS reflectometry for the detection and characterization of sea ice
*Usage of satellite gravity observations for studying the atmospheric water cycle.
