IPMMI Papers to be Submitted to a Special Journal Section

 

Five core papers were discussed to be the heart of a special section in a journal to be chosen.  The outlines for these papers, along with proposed authors (including one head author) are listed below.  The following deadlines are proposed for paper completion and submittal:

31 October 1999      Head authors assign writing portions of paper to co-authors.  Generate intermediate deadlines for calculations, figure completion, preliminary drafts, etc.

15 February 2000     First drafts of papers to the IPMMI science team

15 April 2000           Comments back to head authors

15 May 2000            Revised drafts to paper co-authors

Spring AGU             Workshop to discuss papers, suggest further revisions

30 June 2000           Near final drafts to the IPMMI science team

15 July 2000            Final comments to head authors

31 July 2000            Submittal of papers to journal

 

It was also proposed that papers are prepared in Microsoft Word format (97 or newer) for easy exchange.  Figures should be inserted into separate Word files or remain in a Microsoft Excel Workbook.  Include an Excel file containing the data used to prepare the figure.
