NCEI Accession 0144250 contains surface underway data collected by the research vessel MIRAI in the Indian Ocean, Mozambique Channel, and South Atlantic Ocean from December 2003 to January 2004. The dataset includes measurements of air temperature, barometric pressure, partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, wind direction, and wind speed. These data were collected by Akihiko Murata of JAMSTEC using carbon dioxide gas analyzers and equilibrators as part of the CLIVAR_I03I04_2003_Underway data set.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure measurements.
- Analyzing correlations between sea surface temperature and carbon dioxide fugacity.
- Studying regional oceanographic variability in the Indian Ocean based on underway salinity and temperature data.
- Validating satellite-derived sea surface data with in-situ wind speed and direction measurements.
Strengths
- Data covers a specific research cruise (49NZ20031209) with a defined time range from 2003-12-09 to 2004-01-24.
- Includes multiple key climate variables: AIR TEMPERATURE, BAROMETRIC PRESSURE, Partial pressure of carbon dioxide - atmosphere, Partial pressure of carbon dioxide - water, SALINITY, SEA SURFACE TEMPERATURE, WIND DIRECTION and WIND SPEED.
- Collected by a named principal investigator (Akihiko Murata) from a recognized institution (JAMSTEC).
