The 60 km RUC was a 3-hourly analysis/forecast data analysis system. ARM routinely obtained the analysis and 0-hour RUC results every 3 hours. The analysis product was ingested as the primary source, and the 0-hour product used as a backup. However, when the analysis was not available, the 0-hour forecast was invariably missing as well. In this instance, the 3-hour or 6-hour forecast from a previous analysis was used. This information is documented in the data file header.

The following data streams were produced:
