Project NTAS - Northwest Tropical Atlantic Station for air-sea flux measurement

Archived Data

Notes
As data becomes available it is added to this secton of the NTAS site; it may still be subject to updates, however. Please note the version date as well as the citation for any data you download.

A full description of the OceanSITES NetCDF specification used for UOP datasets is available on the OceanSITES web site. Variable "standard names" are taken from the Climate and Forecast NetCDF specification.

Meteorological data contained on this site is collected by ASIMet loggers. More detailed information about this instrument package is available at http://uop.whoi.edu/asimet/asimet.html.

The ASIMET meteorological sensors on the buoy provided a record of:

• Wind velocity
• Relative Humidity
• Air and Sea surface Temperatures
• Incoming Shortwave Radiation
• Incoming Longwave Radiation
• Barometric Pressure
• Precipitation
