Claim: SAILS is available up to three per volume scan under VCP twelve and 212 with an average scan time of 4.35 minutes.
Evidence: 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. During the summer of 2013, the Radar Operations Center, in order to facilitate "proof of poncept" testing of MESO-SAILS, defined two VCPs that were based on VCP-12 that included hardcoded additional low-level split-cut scans. 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. Doing this provides two low-level scans for each total volume scan while only adding 30 to 35 seconds to the total scan.
