We used to, the company is no longer active. It was really neat data. It was open source code, but it's now a few years out of date, and would maybe be a good idea to rewrite, modernize and bring a big barometer network back online.

On the individual scale, the sensor data was noisy, but in a dense environment with lots of sensors, the noise is identifiable and filterable to get solid pressure trends (actual pressure values is considerably harder).
