Radiosonde Replacement System (RRS)


RRS

The Upper Air Radiosonde Replacement System (RRS) is an effort of the National Weather Service to replace its current network of obsolete radiosonde observing systems using older telemetry equipment with a modern system providing improved data availability and accuracy, which operates within a reduced frequency spectrum, and is more efficient to operate and maintain.

For System Test (ST) any new RRS test software is installed on the RRS Test Systems SP2 at the National Weather Service Headquarters (WSH), Silver Spring, MD, and ST1 at the Sterling Research and Development Center (SR&DC), Sterling, VA.

The SP0 RRS consists of a RRS Workstation Subsystem (RWS) utilizing an External Data Pump (XDP) upper air simulator replaying real upper air soundings. The ST1 RRS is fully configured for use in launching live upper air soundings.

After a successful ST, the test software is ready for Operational Acceptance Test (OAT). A limited number of operational RRS' are selected (usually one from each US continental (region) based upon specific test objectives to validate the test software for all remaining RRS sites.
