Cool, man!!! I just tested this new version of grd_read and... it's very nice!!! The improvement really works.

11 Jun 2013 Small Amplitude Wave Theory Parameters of a water wave, using small amplitude wave theory. Author: Gabriel Ruiz Clark, Thomas

Downgrading my rating after finding more serious bugs in the equations for fluid velocity (U,W) which should not be a function of g according to:
http://en.wikipedia.org/wiki/Airy_wave_theory
More than happy to up my rating again if there is a defence of the system used

At this point it is more rigorous to simply re-write the function rather than comb through line by line looking for more bugs.

re. my previous comment - apologies, the sigma/omega definition is clear and consistent with the intrinsic angular frequency sigma.

The submission is highly unrefined in terms of coding practice. For example, variables (such as z and t) are reassigned during the code, making it very difficult to read.

It is possible this leads to a bug since the values of t are defined in line 82 then redefined as an integer counter in line 98 and elsewhere.

There is a bug in the axial fluid velocity term:
cos(kx-wt)
is expressed as
cos(kx - w-t)
on lines 108, 178 248

... and several similar mistakes are made elsewhere.

Some strange definitions are made - for example 'omega' is labelled 'sigma'.

That said, if you're wanting an implementation of the airy wave functions as defined in the table on this page:
http://en.wikipedia.org/wiki/Airy_wave_theory
It is much easier to alter this function than start from scratch, especially if not familiar with wave theory. So thanks for getting me some of the way there!

15 Nov 2012 julian2greg This function converts the Julian dates to Gregorian dates. Author: Gabriel Ruiz Shish, Kimberlee

You get some accuracy below a single second by taking off the 'ceil' on the second calculations.
