Complex, highly mobile projects such as VORTEX2, ROTATE, and TWIRL, or projects with special needs (e.g. MASCRAD) may require a mobile operations/coordination center, data management office, and repair facility, or a remote staff headquarters vehicle. The MORC (Mobile Operations and Repair Center) is a long sprinter van with multiple scientist/engineer work stations, a wall of monitors, a computer rack, and two generators. A 10 m pneumatic mast houses weather instruments and a high-powered VHF radio for communications with mobile or remote fleets.
