Aside from questions concerning their ethical values and conduct, many have been accredited for giving back to the community in several ways. Just before the Joplin tornado, Storm Chaser Jeff Piotrowski provided advanced warning to Officer Brewer of Joplin local law enforcement, prompting them to activate the emergency sirens. Though lives were lost, many who survived accredited their survival to the siren. After a storm has passed storm chasers are often the first to arrive on the scene to help assist in the aftermath. An unexpected and yet increasingly more common result of storm chasers is the data they provide to storm research from their videos, social video posts and documentation of storms they encounter. After the El Reno tornado in 2013 portals were created for chasers to submit their information to help in the research of the deadly storm.
