ACE-1: R/V Discoverer SO2 Measurements


This dataset consists of preliminary sulphur dioxide (SO2) concentration measurements (fluorescence based HPLC system) taken aboard the NOAA R/V Discoverer by Eric Saltzman (University of Miami) during the ACE-1 cruise. These data consist of time in UTC (julian decimal day) and SO2 in pptv. The data was filtered for stack gas contamination using wind speed and direction and averaged into 30-minute bins (approx. 3 measurements per bin). The data was processed and quality controlled following the ACE-1 field phase. While this dataset is PRELIMINARY, it is not expected to change significantly.
