Students Deploy Rain Gauge Network

Achievement date: 
2014
Outcome/accomplishment: 

As part of NSF’s Research Experiences for Undergraduates (REU) program, students at the NSF-funded Engineering Research Center (ERC) for Collaborative Adaptive Sensing of the Atmosphere (CASA), headquartered at the University of Massachusetts–Amherst, led a project at CASA partner institution the University of Puerto Rico at Mayaguez (UPRM) to deployd a network of twenty rain gauges in the local area.

Impact/benefits: 

CASA’s network in Puerto Rico is composed of NEXRAD, TropiNet Doppler, and Off-the-Grid (OTG) radars. In support of CASA’s initiative to create a network of networks, these types of radars contribute different types of information that are aggregated together to provide accurate and detailed weather measurements.

 

Explanation/Background: 

Weather radars can provide useful information about the distribution of rainfall over an area, but can be erroneous in estimating the amount of rainfall. The gauges installed by the REU students supplement the existing network and are meant to validate the data recorded by other radars. Information collected by the gauges will allow the team to calibrate their other radars and improve their forecasting algorithms. The gauges were installed in pairs at ten different locations around Mayaguez and western Puerto Rico.
