The State Climate Office of North Carolina is one of the most active in the US. Dr. Ryan Boyles is the State Climatologist and he has a staff of over twenty people working in some capacity in the office, including a number of graduate and undergraduate students from North Carolina State University. The office supports the ECOnet, a mesonet of stations across North Carolina, and the CRONOS database system, which I discussed a few weeks ago in this blog. Their Twitter handle is @NCSCO.
The website provides access to a number of interesting data sets, including a hurricane database and a heat index climatology for cities across the Southeast.
If you are interested in hearing more from Dr. Boyles on what it means to be a climatologist, you can listen to his CoCoRaHS webinar from their archive at https://www.cocorahs.org/Content.aspx?page=wxtalk27.
