Comparing Rain-Gauge Data with Radar-Derived Precipitation Estimates

Christopher J. Woltemade and Diane Stanitsky-Martin

This resource received an Accept or Accept with minor revisions rating from a Panel Peer Review process

These materials were reviewed using face-to-face NSF-style review panel of geoscience and geoscience education experts to review groups of resources addressing a single theme. Panelists wrote reviews that addressed the criteria:

  1. scientific accuracy and currency
  2. usability and
  3. pedagogical effectiveness
Reviewers rated the resources:
  1. Accept
  2. Accept with minor revisions
  3. Accept with major revisions, or
  4. Reject.
They also singled out those resources they considered particularly exemplary, which are given a gold star rating.

Following the panel meetings, the conveners wrote summaries of the panel discussion for each resource; these were transmitted to the creator, along with anonymous versions of the reviews. Relatively few resources were accepted as is. In most cases, the majority of the resources were either designated as 1) Reject or 2) Accept with major revisions. Resources were most often rejected for their lack of completeness to be used in a classroom or they contained scientific inaccuracies.

Summary

Student teams collect rain-gauge data and compared it with radar-derived (NEXRAD) precipitation estimates. They use GIS to look for discrepancies between the two datasets and explain them by looking for sources of error in the method. The project culminates in a presentation by the students. The project has since expanded to include units dealing with local hydrology.

Learning Goals

Knowledge

Skills

Context for Use

This is a semester-long project, based on multiple observations.

Teaching Materials

A detailed lesson plan for Comparisons of NEXRAD radar and precipitation gauge values (more info) is provided by the authors.

This project cost the authors $500 to cover:

The institution presumably had other funding for the GIS lab and software.

Teaching Notes and Tips

This activity will require a great deal of training for the students, and will require a lot of time and attention on the instructor's part, so may not be suitable for a large class, especially if there are no teaching assistants available.

Assessment

This project was first run with only four students, so they could be closely supervised by the graduate student on whose project they were working. A presentation similar to those given at professional conferences was deemed appropriate.

References and Resources

This project was designed as part of the Burd Run Interdisciplinary Watershed Research Laboratory (more info)
