NOAA intends to award a sole-source purchase order to InterMet Systems for specific Train Regulators to be delivered to the National Logistic Support Center in Grandview, MO. The justification is that InterMet Systems is the only qualified source capable of providing a compatible part essential for collecting critical upper-air weather data. Firms believing they can meet the requirements may submit substantiating documentation in writing within 15 days of the notice's publication for potential consideration. The services are to support the National Weather Service's Upper Air Program.
