It then returns to swipe an addiitonal 0.5 scan (second second chart) before returning to complete (third chart) the rest of the elevations (4.0 to 19.5, for example). The regular SAILS option begins the scan strategy at elevation 0.5 and advances upward to 3.1 (first chart on the left). SAILS as well as MESO-SAILS is only available when the radar is in VCP (Volume Coverage Pattern) 12 or 212. When the MESO-SAILS 3 Scan Option is active, the 0.5 degree updates will be available every 75 to 90 seconds. This new scan is inserted into the “middle” of the volume scan to evenly space, as close as possible, the time intervals between low-level data updates. MESO-SAILS enables the radar operator to select either 1, 2, or 3, supplemental low level scans per volume scan. The SAILS function allows for one addtional low level scan (0.5 degree elevation angle) per volume scan. The field test will continue for about 1 year. With this upgrade, the KCLE radar began participation in a field test of the Multiple Elevation Scan Option (MESO) for SAILS (Supplemental Addaptive Intra-Volume Scan). The NWS Cleveland WSR-88D Doppler Weather Radar, KCLE, was recently upgraded. MES0-SAILS TEST: New Radar Technology (August 2015)
