This App Uses The Power Of You To Report The Weather

If you love to talk about the weather — or want to help collect information about it — a new smartphone app may be for you.

The National Oceanic and Atmospheric Administration and the University of Oklahoma are giving regular folks an opportunity to fiddle with weather reporting. Using crowdsourcing, the mobile Precipitation Identification Near the Ground app collects geographic, winter precipitation data from users. The mPING app also links to a map showing weather reports sent in by locals.

The data collected by the app will help weather officials program radar to determine exactly what's falling near you. For example, is it hail or mixed rain?

The free app is currently available for the iOS and Android operating systems.

Users anonymously update reports by selecting a variation of winter weather between "none" and "graupel/snow grains,"* their GPS location is noted, and information is sent in to NOAA. (It can also be done through NOAA's website, but an extra step of figuring out your longitude and latitude has to be completed.)

"The purpose of PING is to give us ground observations of precipitation types that are not well observed from automatic systems," Kim Elmore, a science researcher working on the project, told All Things Considered. He says the gathered information will be used to build algorithms for newly upgraded radars.

The data can also help officials and the public prepare for severe weather, he says.

"If we can better marshal our resources for dealing with it, then it may not cost quite so much and people may not be in quite such jeopardy," Elmore says. Throwing salt, buying sand, fixing wires and removing fallen trees can be constant expenses, he adds.

mPING is just the latest weather app to use crowdsourcing. Others include Weddar, which asks users to add a colorful description of the weather; and Metwit, a hyperlocal app that lets you pin photos to your weather reporting.

The app had a "soft launch" in December, but it has already become popular.

Elmore estimates about 20,000 people have downloaded the app and nearly 60,000 reports have been submitted. The project itself has been around since 2006, using different methods like cold-calling to verify falling precipitation.

Much of its popularity may come from the high level of interest in weather and science, Elmore says. The "real hook" is the data readily available for people to view on their phones.

So this app may not break the ice for your weather forecasting career, but it may someday help your local weatherman have an accurate picture of what's going on outside your window.

* In case you're wondering, NOAA's National Severe Storms Laboratory says graupel (aka soft hail or snow pellets) are "soft small pellets of ice created when supercooled water droplets coat a snowflake."
