OpenGrADS and the mfhilo command -- regrid2

[Michael Fiorino]

Tom et al.,

I've been working with Arlindo da Silva to convert my regrid2.f to a
user-defined extension accessible in both opengrads 1.10 (what we're
calling the opengrads version of grads1.9) and opengrads2.0.  that will
be a subject of a future announcement, but as a preview, we've found a
couple of (minor) bugs my old-style user-defined function regrid2.f and
in the user-defined extension re.c and we've made them produce the same
answers with the fortran version as an extension (called 're2') nearly
as fast as the C version 're'

to regrid2 users -- the bug is really minor and does not invalidate any
results using the current version.  the differences will only show up if
your output grid has a pole point and the differences are < 1%.

during this development process i have received a surprising (to me)
number of requests on how to use my user-defined extension 'mfhilo'.

this command is part of a set of user-defined extensions related
to tracking tropical cyclones (and other high/lows) in models.

i reached a milestone my development when i rehosted the
regrid2.f function to opengrads 1.10 and 2.0, and now i'm ready to
actively work the tracking extensions...

please be patient and when i have a version that i think is mostly
working, i'll make an announcement on this list.

thanks for your interest and

best regards,

mike

OpenGrads and figured out a way to plot the H s and L s?  I currently
can do this in the COLA/IGES version of GrADS 1.8 using philo2.gs and
the user defined function clhilo.
