Processing LADCP data with SADCPΒΆ

Shipboard ADCP data can be used to constrain further the velocity field obtained from the Lower ADCP data. We do not ask to process the LADCP data with the SADCP during the cruise, although the operator is free to do so. Be aware that, in that case, the SADCP data are not final –they need to be reprocessed after the cruise–, and errors in SADCP data could occur.

If the SADCP data are processed by UH CODAS, the SADCP data can be reformatted using the routine mkSADCP.m. The routine takes two entries: (1) the path to the processed SADCP data (contour_xy.mat and contour_uv.mat), and (2) the name of the output file including its full path. For instance:

mkSADCP('/net/ipu/export/ipu1/data/projects/clivar/I5S_2009/nb150/contour','/home/science/I5S_2009/proc/ladcp_ldeo/data/ldeo_reprocessed_sadcp/ldeo_reprocessed_sadcp.mat')

During a cruise, this step needs to be done every time new LADCP data needs to be processed. After the cruise, this step needs to be done only once.

Then, in set_cast_params.m, include the name of the file containing the reformatted SADCP data in f.sadcp:

f.sadcp = 'data/ldeo_reprocessed_sadcp/ldeo_reprocessed_sadcp.mat';

Also include the following line (see LDEO How-To [PDF]):

p.sadcp_dtok = 0

Finally, 9 should be added to p.saveplot to save Fig. 9 that shows SADCP data.
