Commenting on a paper
To comment on a paper published in the interactive scientific journal Nonlinear Processes in Geophysics (NPG) or in its discussion forum Nonlinear Processes in Geophysics Discussions (NPGD), please choose one of the following two options:
If you would like to submit an interactive comment (Short Comment, Referee Comment, Editor Comment, or Author Comment) for immediate non-peer-reviewed publication in the interactive discussion of a paper recently published in NPGD, please locate this paper on the NPGD papers in open discussion webpage and follow the appropriate links there.
Short Comments can be submitted by every registered member of the scientific community (free registration is accessible via the login link). They should usually not be longer than 10 pages and have to be submitted within 8 weeks after publication of the discussion paper in NPGD. For details see Interactive Public Discussion.
If you would like to contribute a peer-reviewed comment or reply, which continues the discussion of a scientific paper beyond the limits of immediate interactive discussion in NPGD, please be aware of the Manuscript Preparation.
Such comments and replies undergo the same process of peer review, publication and interactive discussion as full articles and technical notes. They are equivalent to the peer-reviewed comments and replies in traditional scientific journals and may achieve publication in NPG if sufficiently substantial.
LaTeX in Interactive Comments
If you want to use LaTeX commands in your comment you need to "Activate LaTeX Commands" by clicking on the appropriate button just above the text input window.
The following template is a simple ASCII text file with a typical layout for interactive comments and some frequently used LaTeX commands. It can be viewed, edited, copied and pasted into the text field of the comment submission form using any standard text editor: comment_example.txt .
Line and paragraph breaks
Italic and bold text
Italic text may be created by putting the text into curly braces with a \it after the opening brace.
Remember to include the empty space between the \it and the rest of text. Bold face text is produced in a similar way using \bf.
Again, remember to include the empty space between the \bf and the rest of text.
Subscripts and superscripts
To create a subscript, type a dollar sign, an underscore, an open curly brace, the character(s) you want to be subscripted, a close curly brace, and another dollar sign.
Creating a superscripts follows the same procedure with the difference that you need to put a caret sign instead of the underscore.
Some characters have a special function in LaTeX; if you want to use them as a normal character you need to put a backslash in front of them.
Greek symbols can be used by putting the special commands listed below between two dollar signs:
\alpha \beta \gamma \delta \epsilon \nu \kappa \lambda \mu \pi \omega \sigma etc.
Similarly, upper-case Greek letters are produced:
\Gamma \Delta \Lambda \Sigma \Omega \Theta \Phi etc.
Some frequently used mathematical symbols are produced in the same way as Greek symbols:
Typing $<$ will produce <
Simple equations are produced by putting all numbers, symbols and signs between two dollar signs.
