Hi everybody



Sivaprasad Gogineni, Professor and Director of Center for Remote Sensing of
Ice Sheets (CReSIS), University of Kansas, will on the 2nd of November,
give a presentation titled:



*Ultrawideband (UWB) Radars for Remote Sensing of Ice, Snow and  Soil
Moisture*



The presentation will be given in the meeting room, 3d floor (room 32),
from 14:00 to 14:45.



Everybody is welcome. Below is a short abstract describing the content of
the talk.



Best regards,

Eyjólfur



Ultra-wideband (UWB) radars, operating over the frequency range from about
100 MHz to 94 GHz and integrated into small and medium Unmanned Aerial
Systems (UAS), can support scientific and operational research on ice, snow
and soil moisture.   Two major climate-change impacts are related to
sea-level rise and fresh-water resources.  UWB radars in the frequency
ranges of 150-600 MHz and 2-18 GHz integrated into small- and medium-scale
UAS can provide much needed data to improve ice-sheet models for generating
more accurate sea-level rise projections over the century. We need accurate
information on bed topography, basal conditions, and snow accumulation of
large ice sheets in Greenland and Antarctica to improve ice-sheet models.
We also need information on snow water equivalent (SWE) and soil moisture
to manage water resources in the future. Soil moisture is a key variable in
scientific research and operational applications, including the forecasting
of floods and agriculture.  Also, soil moisture controls evaporation of the
land surface and is an input variable in predictions of summer rainfall
over continents.  UWB radars can also provide valuable information ice
sheets as well as on  soil moisture and SWE.

In this talk, I will discuss the need for remote sensing of Ice, snow, and
soil moisture, and present preliminary results from UWB measurements on
these targets. I will also discuss advances required to develop medium and
small UAS integrated with UWB radars to support science and operational
applications.
