Unique commercial light-weight chilled-mirror dew-point sensors were flown on tethered balloons during the Water Vapor Intensive Operation Period (WVIOP) in September 1996. Comparisons were made between in situ and remote sensing instruments that detect water vapor. We obtained a special waiver to fly the sensors up to 1 km both day and night from the FAA. Preliminary comparisons with tower mounted, surface-based temperature/relative humidity probes, rawinsonde, air-borne chilled-mirror dew point, and Raman lidar profiles are included. Profiles during nocturnal boundary layer wind jet occurrences are presented as special cases along with balloon-borne nephelometer light scattering profile comparisons
