</span></span></font></p>
<p>In the context of this session the expression “Geodetic Remote Sensing” comprises atmosphere (including e.g. troposphere and ionosphere) monitoring, space weather studies as well as GNSS reflectometry. In general the Earth's atmosphere can be structured
into various vertical layers depending on physical parameters such as temperature, water vapor or charge state. From the geodetic point of view the atmosphere is nowadays not only seen as a disturbing quantity which has to be corrected but also as a target
quantity, since almost all geodetic measurement techniques provide valuable information about the atmospheric state. A prominent example for these developments is the operational use of ground- and space-based GNSS measurements to improve global and regional
weather forecasts since 2006.<br>
<br>
One of the major tasks in ionosphere research activities concerns the determination of physically relevant parameters from space geodetic observations to monitor ionosphere phenomena, such as the equatorial anomaly, and to perform space weather studies. Space
weather and especially its impacts and risks are gaining more and more importance in politics and sciences, since our modern society is highly depending on space-borne techniques, e.g., for communication, navigation and positioning. Near real-time or even
real-time approaches are currently under development, e.g. to monitor and analyse the state of the ionosphere, to predict ionosphere target parameters, or to optimize ultra-fast tropospheric products using data from GNSS permanent networks. Coupling processes
between different atmospheric layers and inter-relations with climate change and natural hazards are further up-to-date topics. The backbone of all these studies and investigations is the integration of different geodetic observation techniques, consistent
models and appropriate approaches following the goals of the Global Geodetic Observing System (GGOS).<br>
<br>
Another important geodetic remote sensing technique is GNSS reflectometry (GNSS-R). After interacting with the neutral and ionized atmospheric layers, GNSS signals can be reflected off water, ice, and soil surface and exploited to derive geophysical properties
of these surfaces as altimetric height, surface roughness, soil moisture, snow height, humidity or vegetation index. Such products are not only relevant for the geodetic community but also for an interdisciplinary geophysical user community with regard to
important topics such as global sea-level monitoring, hydrological loading or drought/flooding observations.<br>
<br>
In this session, contributions on atmosphere modeling including post-processing and (near) real-time approaches as well as studies on the combination of ground- and space-based geodetic observation techniques (including terrestrial GNSS, satellite altimetry,
radio occultations, VLBI, DORIS) are welcome. Hereby we appreciate studies on the neutral and ionized atmosphere, including space weather related investigations, atmospheric coupling processes and climate change studies. We also welcome studies on GNSS reflectometry
and related geophysical applications. Presentations on the estimation and forecast of atmospheric parameters (including atmospheric data assimilation) and on the usage of numerical weather models to improve GNSS positioning are other examples which would be
appreciated.</p>
