Summary

This is a gridded version of Argo profiling float data from the North Atlantic Ocean and moored MicroCAT CTD data from the RAPID 26N moorings. Data have been reduced to a 1 degree longitude by 1 degree latitude grid using objective mapping. Vertical resolution is 20 decibars; time resolution is 10 days; The data span the years 2004 to 2022. Mapped parameters are in-situ temperature (ITS90) and practical salinity (PSS-78) along with mapping uncertainties in both temperature and salinity. Real-time and delayed mode data with Argo quality flag 1 or 2, and quality controlled RAPID mooring data, were mapped on sigma-1 density surfaces with decorrelation length scale 500 km. Data quality procedures were carried out by the programs that provided the source data. No further data quality control was undertaken prior to mapping. The dataset was created on behalf of the NERC projects ACSIS and CLASS by Brian King of the National Oceanography Centre (NOC). Source datasets for this mapping were: 1) Argo (2023). Argo float data and metadata from Global Data Assembly Centre (Argo GDAC) - Snapshot of Argo GDAC of 10 January 2023. SEANOE. http://doi.org/10.17882/42182#98916. 2) Atlantic meridional overturning circulation observed by the RAPID-MOCHA-WBTS (RAPID-Meridional Overturning Circulation and Heatflux Array-Western Boundary Time Series) array at 26N from 2004 to 2020 (v2020.2), British Oceanographic Data Centre - Natural Environment Research Council, UK. doi:10.5285/e91b10af-6f0a-7fa7-e053-6c86abc05a09. The data are held as a CF-compliant netCDF file.
