If you suffer from pollen allergies, you likely pay at least some attention to the pollen count reports during weather reports. But how do you count pollen? And who does it?

On today's episode of "Brian's Positively New Jersey,” Brian Donohue ascends to a rooftop at Kean University where one of a surprisingly small number of pollen-counting stations is monitored by students and researchers keeping tabs on what's making us sneeze.

Donohue also looks at how artificial intelligence may soon be making the job easier and bring a greater understanding of why there's been an explosion of pollen in recent years.
