Precipitation ID Near the Ground (PING)


Develop radar technologies to detect precipitation
Report precipitation with your Android and iPhone

The National Severe Storms Laboratory needs YOUR help with a research project!

If you live in the area shown on the map, the Precipitation Identification Near the Ground project (PING) wants YOU to watch and report on precipitation type.

PING is looking for young, old, and in-between volunteers to make observations—teachers, classes and families too! We have collected tens of thousands of observations since 2006, already making PING successful because of your help.

PING volunteers can spend a little or a lot of time making observations. The basic idea is simple: the National Severe Storms Laboratory will collect radar data from NEXRAD radars in your area during storm events, and compare that data with YOUR observations.

Why? Because the radars cannot see close to the ground, we need YOU to tell us what is happening. Scientists will compare your report with what the radar has detected, and develop new radar technologies and techniques to determine what kind of precipitation—such as snow, soft hail, hard hail, or rain—is falling where.
