During the past couple of months, a number of new and refurbished boundary layer profilers have become available in North Carolina. Most recently, a 915MHz boundary layer profiler managed by the U.S. EPA in Research Triangle Park (site ID: RTPNC) has been added to the real time data stream and is available in MADIS and online via the links below. A map of the boundary layer profilers and a table of the sites is shown at the bottom of this post. The additional profilers have already proven helpful for near term forecasting at WFO Raleigh as well as forecasting for our aviation and fire weather partners.
The image below is the profiler display of wind speed and direction for the RTPNC location from this morning. The low level northeast flow is apparent in the lowest 2km with an enhancement of the wind speed overnight associated with the low level jet.
The availability of these observational tools is a multi-agency success story that required the assistance of several key partners, and in particular Nick Witcraft (NC DENR), Elliot Tardif (NC DENR), Bradley McLamb (NC DENR), George Bridgers (US EPA), Leon Benjamin (NOAA/ESRL), and countless others from ESRL and the HMT program.
