It needs better tweaking so it can report fog and haze more often. It's hazy here all the time during the summer, but I've only seen haze being reported here once since HiRAD was put into play, and that was in August 2007. Fog and haze is reported a lot more often with the reporting stations.
We also had smoke around here last spring when wildfires were burning in the Pine Barrens, but no HiRAD locations were reporting smoke, even locales located near or within the pine barrens like Fort Dix, Browns Mills, and Lakewood.
