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.
Metadata, including variable's "standard names" are taken from the
Climate and Forecast NetCDF
specification.
Real time data and provisional, partially processed subsurface temperature and salinity
data is available on the Real Time Data page.
Notes on Meteorological Data
Meteorological data contained on this site is collected by ASIMet loggers. More detailed information about this instrument package is available at /UOPinstruments/UOPinstruments.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
Notes on Subsurface Temperature and Salinity Data
Delayed-mode subsurface temperature and salinity data from NTAS 7 - 14 were processed in cooperation with D. Vandemark and M. Emond (U. New Hampshire, School of Marine Science and Ocean Engineering). Key processing steps included timing checks, comparison with data from adjacent depths, assessment during periods of overlap between successive deployments, and comparison with independent data sources (e.g. Argo floats). Data files are separated by measurement type and sample interval.
Download Data
NetCDF (OceanSITES standard) files

All data presented here should be considered provisional, as
further adjustments to the data may be needed.
