Gilmore and Shawn Smith World Ocean Circulation Experiment(WOCE) Surface Meteorological Data Assembly Center Center for Ocean Atmospheric Prediction Studies The Florida State University August 1, 1996 Report WOCEMET 96-9 Version 1.0 Introduction: The data referenced in this report were collected from the research vessel Melville (call sign: WECB; data provider: Scripps Institute of Oceanography/ Woody Sutherland) IMET automated data collection system from 2 different cruises. The data were recieved in electronic format and converted to the FSU standard format. Then they were preprocessed using an automated data checking program. Next a visual inspection was completed by a Data Quality Evaluator who reviewed, modified and added appropriate quality control (QC) flags to the data. Details of the WOCE QC can be found in Smith et al (1996). The data quality control report summarizes the flags for the Melville data, including those added by both the preprocessor and the analyst. Statistical Information: The data from the Melville were expected to include observations every minute from 2 cruises, each of which was completed in 2 legs. The start and end dates, the number of observations, and the number and percentage of non-Z flags for each leg are given in table 1. Table 1 includes flags added to DIR and SPD. Time (TIME), latitude (LAT), longitude (LON), atmospheric pressure (P), air temperature (T), sea temperature (TS), relative humidity (RH), humidity temperature (T2), atmospheric radiation (RAD), (RAD2), and accumulation of precipitation (PRECIP) were quality controlled. A total of 1,312,800 values 2 were checked with 153,904 flags added resulting in 15.99 percent of the values being flagged. The distribution, including percentages flagged for each variable sorted by type, excepting SPD and DIR, is detailed in table 2.
