The National Oceanic and Atmospheric Administration (NOAA) intends to issue a sole-source purchase order to WeatherBell Analytics LLC for 155 professional software licenses to be delivered electronically. The sole-source justification is that WeatherBell is identified as the only vendor capable of providing licenses with specific, required data visualizations from key meteorological prediction systems. Delivery is required as soon as possible. This is a presolicitation notice, not a request for competitive proposals, but firms believing they can meet the requirements may submit substantiating documentation to the point of contact.
