With Hurricane Isaias hitting before tonight's Alabama-Georgia game, Alabama's SubAir system will be tested. Alabama installed the system beneath its football field as part of a multi-million-dollar renovation project. Fourteen wireless underground sensors monitor conditions like moisture, temperature, and oxygen. The system then pulls moisture out through a drainage system when the field gets too wet. The company that installed the system says it can do an hour's worth of drainage in about three minutes. The system also has built-in temperature controls with an underground heating system, allowing Alabama to heat up the field when it gets cold. This is the same system used at Augusta National, and it paid off when Alabama received half an inch of rain before its 2023 home opener. The SubAir system automatically kicked on, and in just 17 minutes, the moisture level dropped from 25% to 16% — the exact level Alabama likes to play all its football games at. Pretty cool!
