The Standard Hydrometeorological Exchange Format (SHEF) is a documented set of rules for coding data to be shared between visual and computer systems.

Depending on which "SHEF" you are researching, the following essay outlines examine their respective purposes and impact. Option 1: The SHEF Manual in Hydrometeorology

The manual allows disparate software systems to communicate. By following the "SHEF code," local weather offices can transmit raw data that is automatically parsed by central modeling computers, reducing human error in manual data entry.

At its core, the SHEF manual provides a uniform language for recording river stages, precipitation levels, and reservoir data. This standardization is critical for the National Oceanic and Atmospheric Administration (NOAA) to maintain real-time hydrologic forecasting.
