Download files that contain the factors needed to undo cold water tapering of XBT profiles

These tar files contain a factor (in the FACTORS variable) for each profile in the profiles files. If the factor for an XBT profile is not 1.0, simply multiply the depths by the factor to restore the depths to the Hanawa standard.

Details

Most recent update

The most recent data to be added were for April 2012.

Description

EN3_v2a is an update of previous versions of the EN3 dataset:

To pick up any changes in the source data, these have been re-downloaded from WOD05, GTSPP and Argo (either from Coriolis or USGODAE). Additional Arctic data compiled at NOCS as part of the ASBO project were also included. Please see the data sources page for more information about these.
Argo data are now rejected if they are included on the Argo grey list (obtained from the Coriolis ftp site, or if they are included in a list of suspect floats based on comparisons with altimeter data (ftp://ftp.ifremer.fr/ifremer/argo/etc/argo-ast9-item13-AltimeterComparison/ ; Guinehut et al. 2008).
Problems with observation times in previous versions (see, for example, the notes at the top of the EN3_v1c download page) have been fixed. However, please note that the ASBO dataset stores only the date of observation and not the hour/minute/second. Therefore, these observations have been given an observation time of midday UTC.
This dataset has not had any of the recently proposed time varying XBT bias corrections applied. Go to the Download EN3_v2a_NoCWT_WijffelsTable1XBTCorr page for some XBT bias corrected data.

This version of the dataset will be updated each month.

How to download

Use the links on the left to download version 2a of the EN3 dataset a year at a time. Available for download are files containing profiles, files containing the objective analyses and files containing the multiplication factors needed to undo the cold water tapering that is performed when some XBT depth corrections were applied.

If you require the whole dataset one way to do this is to use wget. To do this download one of the files below (and edit it if not all files are required).
EN3_v2a_Profiles_download_list.txt
EN3_v2a_ObjectiveAnalyses_download_list.txt
EN3_v2a_CWTFactors_download_list.txt

Assuming that you are in the directory into which the data are to be copied and that the downloaded file is also in that directory, the download can then be initiated by typing at the command line:
wget -i EN3_v2a_Profiles_download_list.txt
or
wget -i EN3_v2a_ObjectiveAnalyses_download_list.txt
or
wget -i EN3_v2a_CWTFactors_download_list.txt

Note: the above method was written for Linux systems but should also be applicable to other operating systems with wget installed.
