"Best" decided by subject matter experts based on experience, evaluation of data comparison of like variables measured simultaneously on the buoy, and comparison of like variables on buoys deployed before/after. The convention for wind direction is "oceanographic", i.e. direction towards not direction from. flux_data_info: Output of COARE 3.6 bulk flux algorithm run on NTAS buoy best--basic-met. The sign convention for heat flux is positive for flux into the ocean. The cool skin and warm layer functions of COARE were both used. Waves were not used as input to COARE at this time. Convention for momentum flux is oceanographic; direction toward ocean_data_info: These ocean data are uncorrected for pre/post calibrations, and in-situ density inversions, which indicate some cal/drift problems. Expected errors: Temperature error +/- 0.01 deg C ... Salinity error +/- 0.02 PSU averaging_info: All met variables are recorded at 1 min intervals, then averaged to 1 hr. Time stamp is half way through the average, e.g. at 30 min past each hour. Fluxes are computed from hourly averages. future_data_plans: surface currents and wave data will be released soon. Data record will also be extended in time soon. m.meta.processing_date: 30-Jul-2020 data_assembly_center: WHOI-UOP source: Mooring observation cdm_data_type: Station experiment: NTAS: Northwest Tropical Atlantic Station deck_height_cm: 75 watch_circle_nm: 4 water_depth: 5021 wmo_platform_code: 48401 ndbc_platform_code: 41NT0 naming_authority: OceanSITES anchor_times: 10-Jun-2018 20:53:00 and 16-Jan-2020 10:41:00 anchor_over_time: 10-Jun-2018 20:53:00 anchor_release_time: 16-Jan-2020 10:41:00 data_start_time: 05-Jun-2018 20:53:00 magvar: -16.9814 and 16.9542 in degrees.... the compass in a anemometer or current measures magnetic north, but we want the results in geographic north. For a given lat/lon on the earth at a given time, there are magnetic field models that provide the angular offset that you need to apply to your compass to get geographic north. That is the "magvar correction", and the magvar variable is the rotation angle in degrees. duration_days: 584 start_year: 2018 deployment_cruise: PC1803 recovery_cruise: RB2001 m.meta.history.salinity_calc: source: GSW_matlab_v3_05_6 ; press_used: 0.7544 m.meta.platform.magnetic_variation.annual_drift_east: 2.5818 m.meta.platform.magnetic_variation.contact: geomag.models@noaa.gov m.meta.platform.magnetic_variation.input: latitude: 14.8245 ; longitude: -51.0166 ; date: 30-March-2019 m.meta.platform.magnetic_variation.model: International Geomagnetic Reference Field (IGRF2015)International Association of Geomagnetism and Aeronomy (IAGA) International Geomagnetic Reference Field (IGRF 12) m.meta.platform.magnetic_variation.source: NOAA > NESDIS > NGDC m.meta.platform.magnetic_variation.URL: https://www.ngdc.noaa.gov/geomag/calculators/magcalc.shtml#declination m.meta.platform.magnetic_variation.value_to_be_applied: -16.9814
