Programming Tips: (First Lab/Disc Period)

• Dr. Grotjahn's programming advice from decades of experience. Please read! You might not agree with everything here, but you may learn things that help you in the long run.

• Types of programming errors. Please read! It is useful to be aware of the numerous sources of errors in the final result. There are some tips on common mistakes that people make; knowing those may save you some frustration later....

• A primer on using formatted writes for printed (and even plotted) output. This is mainly intended for those who have little experience producing attractive, custom output.

• Publication quality graphics are possible using NCL, the NCAR Command Language. Note that NCL uses its own scripting language that is partly a mashup of C++ and FORTRAN. It is powerful and the NCL website has lots of atmospheric science examples, including code, graphics, and documentation.

• Manipulating netCDF and grib files is faciliated by the unix/linux commands of NCO the netCDF Operator.

• Some advice for using NCAR graphics. This is mainly for those who have never used NCAR graphics before.

• A subset of the fortran 77 compiler options are listed here.

• Dr. Grotjahn's "Laws" of computing (slightly tongue-in-cheek, there are grains of truth here which somewhat capsulize information in the "advice" and "errors" links above.)

Documents related to formal lectures on Fortran:

• linux commands summary in .pdf format.
• A compact, general fortran 90 lecture slides in .pdf format.
  We shall review parts of this lengthy (416 slide) document. Mainly focusing on slides 1-130, and parts of the 'A Frotran Survey 2' until about slide 229.
• fortran 2003 intro in .pdf format. It includes lots of examples. (There are some grammar errors.)
• fortran 95 intro in .pdf format. Another resource for info on commands. Running a program varies with the OS.

Directories for presentations, programs, and assignments:

• directory of assignments in .pdf format.
• directory of Fortran presentations and programs in .txt, .pdf, .pptx, or .f95 format.
• directory of NCL presentations and programs in .pdf, .ppt, or .pptx format.

• directory of presentations, programs, and assignments in .txt format or .f format.

• fortran program 1 in .docx format. Used in the Salvadore et al lecture slides.
  fortran program 1 in .pdf format.

Web pages related to formal lectures:

• Directory for some transparencies used in some of the lectures. The format is "lecture#_order#.gif" where the order# is the likely order the transparency was shown. So, 4_3.gif was the 3rd transparency of the 4th lecture, etc.

• Lecture group #1: A compact, general fortran 77 & 90 guide in .pdf format.
  We shall review most of the guide. You may skip the following sections: 1.7.4, 2.5.7, 2.5.8, 2.5.9, 2.5.10.

  In case anyone is so foolish as to claim that FORTRAN is dead, or irrelevant, or inferior to some other language (Pascal ca 1984; C ca 1990; C++ ca 2000, -- sigh -- ) try to remain polite and patient and aske them to consider this link.
  That link is contained in a larger FORTRAN tutorial.

  Another source of Fortran 90 information in short html-format web pages is: C.-K. Shene's Introduction to FORTRAN 90.

  There are other tutorials available on the web. Enjoy!

• Lecture group #2: Grid Points and Taylor Series to approximate a second derivative using finite differences.

• Lecture group #3: types of numerical approaches for solving integrals (under const.)

• Lecture group #4: types of numerical approaches as deduced from the canonical forms of the equation(s).

• Lecture group #5: Using Taylor series to construct a 4^th order finite difference scheme for the first derivative. .pdf file

• Lecture group #6: Time integration by flipping indices .pdf file

• Lecture group #10: types of numerical approaches for solving multi-dimensional elliptic equations. (under const.)

UNDER CONSTRUCTION BELOW THIS POINT!
