NOAA intends to award a sole-source purchase order to HTE Technologies Inc. for replacement Atlas Copco compressors for the National Logistics Support Center’s Upper Air Program in Grandview, MO. The sole-source justification is based on the need for compatibility with existing mounting plates, as alternative compressors would require costly testing and cause delays. Failure to replace compressors promptly could force AROS units in Alaska to shut down, halting upper air observations and impacting weather forecasts and warnings. Interested firms may submit substantiating documentation to the Contract Specialist within 15 days of this notice for consideration of competitive procurement. No budget amount or submission deadline is specified.
