Project Description: 

Polarimetric Radar for Examining Streamflow and Soil Erosion Studies :: PRESSES

Principal Investigator :: Dr. Neil Fox
Where :: University of Missouri - Columbia, MO
When :: 8 - 29 September 2012
Facility :: Doppler On Wheels

The University of Missouri requested a three-week (8 Sept – 29 Sept 2012) on-campus deployment of one of the dual-polarimetric Doppler on Wheels (DOW) radars managed by the Center for Severe Weather Research (CSWR). We plan to use the DOW for the following education and outreach activities:

  1. Student-Directed Field Research
  2. Lecture and on-campus DOW demonstration for general education students
  3. Class Activities
  4. K-12 Outreach

With the advent of a national network of dual-polarization meteorological radars, 2012 is the perfect time to demonstrate the range of advantages offered by this upgrade. Primary amongst these is the application of meteorological technology to agricultural issues such as rainfall, runoff, and soil erosion. The activities during the visit of the DOW would center around how dual-polarization can improve weather forecasting, rainfall observation and flood forecasts.

There is particular drive at the University of Missouri toward interdisciplinary studies, In particular there is a specific program (Mizzou Advantage) that encourages the establishment of interdisciplinary teams of undergraduate students. One such team exists that is studying issues of stormwater management and this project would aim to build on that experience by extending that program to look at a comparison of stormwater and streamflow predictions from a variety of precipitation observing systems: rainguages, NWS reflectivity radar products, NWS dual-polarization radar products, and DOW observations. The hypothesis would be that local dual-polarization radar can improve the accuracy and spatial representation of the rainfall such that runoff and streamflow can be better quantified.

PRESSES Final Report

The idea of the PRESSES project was to collect precipitation observations over a sensitive urban catchment and relate rainfall retrievals from The DOW data and from surface based instrumentation. The precipitation observations are then to be used to model run-off into the creek, along with surface transport of sediment. Streamflow observations and measurements of sediment load were also collected. The overarching goal is to test whether the finescale radar observations available from the DOW, combined with drop-size distribution data from the dual-polarization capability, and detailed land cover information can improve estimates produced using other instruments.
