TSTool / Datastore Reference / SHEF


SHEF (Standard Hydrologic Exchange Format) is a data exchange format commonly used by the National Weather Service and other government agencies. The format is typically used in real-time operations to transfer data for many collection points and data types. However, the format is also used to exchange time series data.

Refer to the Standard Hydrologic Exchange Format, Version 1.3.1 (or later), Weather Service Hydrology Handbook No. 1., U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Weather Service.


  • The TSTool software currently supports writing time series to SHEF .A format files on a limited basis. This functionality has received limited testing and is not completely integrated into TSTool as commands.
  • This documentation will be expanded as additional SHEF support is added.
