Daily Mission Update / Student Blog Entry

Over the next 6 weeks, scientists from around the country are taking part in a large field project coined: Plains Elevated Convection at Night, or PECAN for short. PECAN, which began on 1 June, is a multi-agency project (NSF, NOAA, NASA, DOE) funded by the National Science Foundation. The campaign is intended to study four meteorological phenomena related nocturnal convection: Mescoscale Convective Systems (MCS), Low-Level Jet (LLJ), Convective Initiation (CI), and Undular Bores. The project includes both mobile and fixed PECANáIntegrated Sounding Arrays (PISAs), dozens of in-situ instruments, mobile radars, mobile mesonet vehicles, balloon-launching vehicles and many others. The majority of the equipment and mobile weather instruments are stationed in Hays, KS.

On Saturday, May 30, PECAN sponsored an open house, located at Fort Hays Regional Airport. The majority of the equipment that will be in use over the next 6 weeks was on display for the public to see. The photos below, captured by meteorologists at the National Weather Service in Dodge City (@NWSDodgeCity) show some of the sights through the course of the day.

Since 1 June, there have been four PECAN missions, one of which being a "shakedown" mission to test communications and logistics. The other missions included: LLJ (3 June), MCS (4 June), and Bore (5 June).
