gher-ulg/DIVA: v4.5.1

DIVA (Data-Interpolating Variational Analysis) is a software tool dedicated to the spatial interpolation of in situ data in oceanography.

Version 4.5.1 was released in March 2013 and includes the following new features, partly based on the feedback we got from the DIVA workshop 2012 in Roumaillac.

• Advection constraint with linear decay rate and local sources (such as found for radioactive tracers and river discharges)

• divadetrend now allows one to change easily the order in which detrending is done (for example first years then months or the inverse)

• two new error calculations are provided:

1. one quick version divacpme with better quality than the original quick version of the poor man’s error;
2. the other divaexerr is an almost exact error calculation much faster than the exact calculation.

These two options will be implemented into the 4D version for version 4.6.0 so that error fields will be available with more reasonable CPU times for final climatology productions

• Simplification of installation and compilation with additional tests of correct installation

• Housekeeping of the code (simplifications, error messages, cleaning up of code, further optimisations, elimination of depreciated tools)

• New documentation largely augmented with examples and new tool descriptions

• Possibilities to call DIVA from other software via system calls, exemplified by a matlab function divagrid.m

• divadoxml adapted to new specifications from IFREMER
