The calibrated hourly NEXRAD data provides the most accurate available historical rainfall data for the Edwards Aquifer region. The EAA compiles the rain gauge data into hourly totals for archiving and uses these data to calibrate the NEXRAD radar rainfall data over the Edwards Aquifer region. Thus, the main utility to the EAA of the rain gauge network is as a source of “ground truth” for calibrating NEXRAD radar rainfall data. However, the NEXRAD data need to be calibrated based on ground observations from the rain gauges. Next-Generation Radar (NEXRAD) rainfall data from the National Weather Service provides rainfall estimates that are continuous over the entire region.

Additionally, rain gauges can be susceptible to occasional clogging or other malfunctions and fail to record some rain events. Individual rain gauges are not always reliable indicators of true rainfall over a large area because precipitation can vary significantly, even over short distances. These rainfall data are made available to the TexMesonet for inclusion in the statewide earth observation network. The EAA rain gauge network collects rainfall totals every five minutes from over 70 gauges throughout the region.
