List of Revisions

The following is a list of major additions and revisions that have been made to the Acoustic Doppler Current Profiler Data Processing System since its original release in November 2000. Minor revisions include syntax errors in MATLAB version 7.0 and higher. These minor revisions will not be discussed; however, a list of all the functions and their latest revision date can be found in the File Inventory Section of the Appendix.

Additions:

Added pressurecalcs.m function which calculates the mean sea level and tidal fluctuation derived from the raw pressure sensor data.
Added fixorientation.m function which is a convenient way for the user to change the orientation of the instrument in the netCDF file if it was incorrectly read.
Added fixmetadata.m function which allows the user an easy way make additional changes to appropriate metadata data in the epic netCDF file after it has been created.
Added tiltrim.m to more accurately trim the bins on a beam by beam basis for instruments that have significant tilt.

Revisions:

Updated batch files to reflect the additional functions.
The ADCP Processing System calculates depth and trims the bins by first checking for a pressure sensor, and pressure if it is not available, it will use the SURFACE.EXE program for RD Instruments. The SURFACE.EXE program is only used for upward oriented ADCPs. Lastly, if the user does not have the SURFACE.EXE program, the ADCP Processing System will ask for user input values for the depth and mean tidal range.
Revised rdi2cdf.m so that the format of the global sensor attributes are now more informative in name.
Revised rdvlead.m so that it accepts full range of values for pressure sensor.
Removed fill_Value for time and time2 definitions in the epic netCDF file creation.
Reformatted the search for the RD Surface program to allow a more convenient 'browse-to' dialog box.
Updates to dialog boxes to enter important metadata.
