Microbarograph - ESRL Hi-Res Microbarograph, Wasco Airport - Raw Data

**Overview**

High-precision barometers (Paroscientific 6000-16B-IS) are combined with Nishiyama-Bedard Quad Disk pressure probes, measuring pressure (mb) at the surface, nominally 2 m above ground level. Data are sampled at 20 Hz for potential studies of turbulence. The sensors' high accuracy makes them useful for determining horizontal pressure gradients and their relation to wind ramp events, as well as the temporal variability of pressure associated with mountain wakes and waves.
 
**Note different ASCII file formats for Goldendale (z04) and Walla Walla (z09) sites.**
