MESO-SAILS

Multiple Elevation Scan Option for Supplemental Adaptive Intra-Volume Low-Level Scan (abbreviated MESO-SAILS), is a dynamic scanning option for the WSR-88D, controllable by the operator of the radar, when in VCP mode 12 and 212, and additionally 35 and 215 with the Build 18 update scheduled for October 2017. When active, anywhere from one to three supplemental low-level scans can be added to any volume, increasing overall low-level data availability and improves general severe weather detection, as needed. When active, per the National Weather Service, low-level updates will be available "every 75 to 90 seconds". rdf:langString
