General: Manuscripts must be typewritten, double-spaced with wide margins on one side of white paper (A4 or Letter). Good quality printouts with a font size of 12 are required. All pages must be numbered. The corresponding author should be identified (include a Fax number and E-mail address). Full postal addresses must be given for all co-authors. Authors should consult a recent issue of the journal for style if possible. An electronic copy of the paper should accompany the final version. The Editors reserve the right to adjust style to certain standards of uniformity. Authors should retain a copy of their manuscript since we cannot accept responsibility for damage or loss of papers.

Paper Length: Maximum length 25 pages including diagrams, references and tables will be strictly enforced. The text must be less than 8000 words in length.
Spelling: British or American but not a mixture of both.

Title: Long enough to be informative. Avoid chemical formulae in title. If the paper covers a specific location, this should usually be mentioned in the title.
Abstracts: English, 500 words max. Give all main points of whole paper. Do not repeat title. Avoid specialist terms. Do not give full references.
Key Word Index: Include five key words.
Text: Follow this order when typing manuscripts: Title, Authors, Affiliations, Abstract, Keywords, Main text, Acknowledgements, Appendix, References, Figure Captions and then Tables. Do not import the Figures or Tables into your text. The corresponding author should be identified with an asterisk and footnote. All other footnotes (except for table footnotes) should be identified with superscript Arabic numbers.
Units: S.I. unless this is precluded by nature of measurements, in which case conversion factors must be given. Use negative indices rather than / and leave space between symbols, e.g. m s-1 not ms-1 or m/s.
Symbols: Define in text or in a list of notation where units or dimensions should be given.
Maths: Type if possible. Avoid double subscripts or superscripts. Punctuate carefully.
References: All publications cited in the text should be presented in a list of references following the text of the manuscript. In the text refer to the author’s name (without initials) and year of publication (e.g. “Since Peterson (1993) has shown that…” or “This is in agreement with results obtained later (Kramer, 1994)”. For three or more authors use the first author followed by “et al.”, in the text. The list of references should be arranged alphabetically by authors’ names. The manuscript should be carefully checked to ensure that the spelling of authors’ names and dates are exactly the same in the text as in the reference list.
References should be given in the following form: In the text as: Smith (1950) or (Smith, 1950) according to content of sentence, list in alphabetical order of first author’s surname at end of text as follows:

Author’s name(s), initials, year of publication, title: Periodicals title should be written out in full, volume number and inclusive page numbers.
Fermi, E., Marshall, L., 1974. On the interaction between neutrons and electrons. Physics Review 72, 1139-1146.
Books references, title pages, publisher’s name and location: 

Thring, M. W., 1957. Air Pollution, pp. 132-134. Butterworths, London.
Internal publications, conference proceedings, etc.; include sufficient information for the reader to locate the reference. In particular references to conferences should contain the address of the organization responsible.
Illustrations: All illustrations should be provided in camera-ready form, suitable for reproduction (which may include reduction) without retouching. Photographs, charts and diagrams are all to be referred to as “Figure(s)” and should be numbered consecutively in the order to which they are referred. They should accompany the manuscript, but should not be included within the text. All illustrations should be clearly marked on the back with the figure number and the author’s name. All figures are to have a caption. Captions should be supplied on a separate sheet.
Line drawings: Good quality printouts on white paper produced in black ink are required. All lettering, graph lines and points on graphs should be sufficiently large and bold to permit reproduction when the diagram has been reduced to a size suitable for inclusion in the journal. Dye-line prints or photocopies are not suitable for reproduction. Do not use any type of shading on computer-generated illustrations.
Ordinates: Label with adequate graduations. Give three intermediate points (normally x2, x3, x5) between the decades on logarithmic scales.
Photographs: Original photographs must be supplied. If necessary, a scale should be marked on the photograph. Please note that photocopies of photographs are not acceptable.
Tables: Tables should be numbered consecutively and given a suitable caption and each table typed on a separate sheet. Footnotes to tables should be typed below the table and should be referred to by superscript lowercase letters. No vertical rules should be used. Tables should not duplicate results presented elsewhere in the manuscript (e.g. in graphs).
Acknowledgements: As brief as possible, in a separate section before the references, not in the text or as footnotes.
Appendix: Items of interest only to specialists in the author’s field e.g. model formulations. Descriptions of methods, experimental results, etc. Symbol lists may also be included here.
Sub-Divisions: Number sections of the paper (and if necessary sub-sections) if there is any substantial cross-referencing within the paper.
First Submission: Some papers, particularly modelling studies, may need extra documentation at the refereeing stage. Please include copies of relevant internal reports, papers in press etc.
Revised Manuscript: Return two copies of the revised manuscript and a disk with the word-processed text. Include a brief note of your response to the referees’ comments. Highlight substantial changes on one copy of the manuscript, using a coloured pen. At this point figures should be properly drafted and of publication standard.
Electronic Submission:
Authors should submit an electronic copy of their paper with the final version of the manuscript. The electronic copy should match the hardcopy exactly. Always keep a backup copy of the electronic file for reference and safety.
