Spatial Pressure Perturbation Analyses utilizing Earthscope's USArray Network
Time series at each reporting site are band-pass filtered and assessed for significant perturbation events to provide case examples of significant phenomena. Gridded pressure analyses from the Rapid Refresh (RAP) are also filtered to create perturbation background fields. Observations are combined with the background fields to produce spatial maps of pressure perturbations to assess the impact of the observations on the analyses in perturbation space. Examples are provided from several significant weather events that traversed the array and produced prominent pressure perturbations within the region.
