Abstract

NCAR's Earth Observing Laboratory (EOL) In situ Sensing Facility (ISF) deployed all of its instrumentation in the Sundowner Wind EXperiment (SWEX) in April–May 2022 to characterize downslope winds along the southern slopes of the Santa Ynez Mountains in Santa Barbara (SB) County, California. The goal was to understand boundary layer processes and mechanisms that favour sundowners. ISF provided ground-based surface and remote sensing observations, sounding systems, operations expertise, data quality control and archiving. This paper describes the measurement system employed and important aspects of the data quality control and management process. The ISF observing system can serve as a prototype to build an integrated network of profiling and flux measuring instruments to better understand the complexity and inhomogeneities within the lower troposphere.
