Natsushima Quality Control Report Christopher Harvey Tropical Ocean Global Atmosphere (TOGA) Coupled Ocean Atmosphere Response Experiment (COARE) Surface Meteorological Data Processing Center Center for Ocean Atmospheric Prediction Studies The Florida State University August 1, 1995 Report COAREMET 95-8 Version 1.0 Introduction: The general surface meteorological data referenced in this report were collected from the research vessel Natsushima (call sign 7JDU; data acquired from the Japan Marine Science and Technology Center) for TOGA COARE during the Intensive Observing Period (IOP). All data were converted to a standard format and were then preprocessed using an automated data quality checking program. The data were then visually inspected by a data quality analyst who reviewed, modified, and added appropriate quality control (QC) flags to the data. This report summarizes the flags for the Natsushima data sets, including both flags added by the preprocessor and the analyst. Statistical Information: The data from the Natsushima during the IOP were expected to include standard observations every three hours from a cruise which began on February 2, 1993 and lasted for 17 days. Time (TIME), latitude (LAT), longitude (LON), wind direction (DIR), wind speed (SPD), atmospheric pressure (P), temperature (T), dew point temperature (TD), relative humidity (RH), and sea surface temperature (TS) were quality controlled. A total of 1,320 values were reviewed and checked and no flags were added resulting in 0% of the data being flagged. Summary: As the statistical information indicates, the data from the Natsushima were in extremely good condition. No problems occurred and the analyst does not foresee any problems in using the data.
