Matlab formats are available on demand CODES AND CONVENTION TO USE THE DATA ------------------------------------------------------------------------------- ---NETCDF FORMAT--- Amundsen Science Core Data are provided with the NetCDF (Network Common Data Form) Format (.nc). NetCDF is widely used among the oceanographic and all Geosciences communities and satisfies criteria of open, long-term access and data preservation. ---SOFTWARES--- Several softwares allow to work with NetCDF datafiles (Matlab, ArcGIS, R, ncBrowse, etc.). ncBrowse is free of charge and can be downloaded at: http://www.epic.noaa.gov/java/ncBrowse/ ---ACCESS TO COMPLETE METADATA--- Open ncBrowse Open the data file of interest Select View in the main menu As table or As tree More meta-information is included with each variable using: Select the Variable for Display, available on the main ncBrowse window. ---DATA FILE CONVENTION--- COARDS: Cooperative Ocean/Atmosphere Research Data Service ---VARIABLES--- Variables in this CODAS short-form Netcdf file are intended for most end-user scientific analysis and display purposes. For additional information see the CODAS_processing_note global attribute and the attributes of each of the variables. ============= ================================================================= time Time at the end of the ensemble, days from start of year. lon, lat Longitude, Latitude from GPS at the end of the ensemble. u,v Ocean zonal and meridional velocity component profiles. uship, vship Zonal and meridional velocity components of the ship. heading Mean ship heading during the ensemble. depth Depth in nominal meters (not corrected for sound speed profile). tr_temp ADCP transducer temperature. pg Percent Good pings for u, v averaging after editing. pflag Profile Flags based on editing, used to mask u, v. amp Received signal strength in ADCP-specific units; no correction for spreading or attenuation. ============= ================================================================= ---CODAS processing note--- See CODAS_processing_note.txt ---END------------------------------------------------------------------------- Please, let us know if you have comments, we welcome your feedbacks.
