Microbarograph - ESRL Hi-Res Microbarograph, Goldendale - Reviewed 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.**

概述

高精度气压计（Paroscientific 6000-16B-IS型）与西山中林-贝达尔四盘气压探测器相结合，测量地表上方约2米处的气压（毫巴）。数据以20赫兹的采样率进行采集，以便进行湍流研究的潜在应用。传感器的超高精度使其适用于确定水平气压梯度和其与风阶事件的关联，以及与山脉尾流和波浪相关的气压的时变特性。
