Evaluation of LMRFC Multi-Sensor Precipitation Estimates Using Independent Rain Gauge Network

This report presents the ongoing evaluation of the Lower Mississippi River Forecast Center's Multi-Sensor Precipitation Estimates (MPE) utilizing a dense network of rain gauges established by the University of Louisiana (UL)-Lafayette. With gauges installed both before and after September 2006, the study analyzes rainfall data and discharge metrics from various gauge stations in New Orleans. The results indicate good overall monthly statistics with steady improvements each year. Future work includes enhancing caution in using multisensor data and exploring vertical profiles of Level II data.
