NONE NOTES: (1) The above legend category information is in a hierarchical classification system. Each legend category consists of a major heading with up to three additional sub-headings, each heading being separated by a unique delimiter character ("|") in the legend category description. All legend categories that fall under any particular heading have that heading repeated in the legend category description. An example will illustrate this. In the classification structure 5.D has the major heading "FORB FORMATIONS", but there is no vegetation class in the data set for this category and so it has no legend category. However, 5.D.2 "Low forb communities (<1m)" (a sub-heading under "FORB FORMATIONS") does have a vegetation class in the data set (number 175) and so the legend category description reads "FORB FORMATIONS | Low forb communities (<1m)". Furthermore, 5.D.2a "perennial flowering forbs and ferns" (a sub-sub-heading under "Low forb communities (<1m)" under "FORB FORMATIONS") also has a vegetation class in the data set (number 176) and so the legend category description reads "FORB FORMATIONS | Low forb communities (<1m) | perennial flowering forbs and ferns". (2) The above legend information reflects minor revisions from that presented in Mathews (1989).

(2) Please note that the flux values presented in Matthews (1989) were later revised (see Fung et al., 1991). TECHNICAL REPORT Mark A. Ohrenschall NOAA National Geophysical Data Center Boulder, CO Data were read from floppy disk and converted to the GED format, separating each variable into different GIS files without altering the original numerical values. Legend information was entered from the accompanying documentation. All final data files were inspected for agreement with the original data. The methane emission spreadsheet (see DATA ELEMENT: Methane Emission, above) was entered by hand from Table 6 in Matthews (1989). *MATTHEWS AND FUNG WETLANDS METHANE ANCILLARY ENVIRONMENTAL DATA Wetland Type #\data\ncillary\mfwwet.img Wetland Data Sources #\data\ncillary\mfwsrc.img Fractional Inundation #\data\ncillary\mfwfrin.img Vegetation Type #\data\ncillary\mfwveg.img Soil Type #\data\ncillary\mfwsol.img Scanned Documentation #*MF SCANNED DOCUMENTATION *MF SCANNED DOCUMENTATION_help The scanned documentation noted here is contained in the \document directory on the CD-ROM as .gif files. These files can be read by any computer program that reads PC Paintbrushformat files. The GeoVu software provided on this CD-ROM contains such a utility. To use the GeoVu utility, merely select the appropriate file from this menu, using the "Open Data" option that you have been using to this point. If you are VERY NEW to GeoVu, you can open a file by 1. Selecting "File" from the options at the top of your screen. 2. After selecting "File" select "Open Data" from the options that appear in the pull-down menu. 3. Follow the hierarchy of menu paths to the data of your choice. 4. When the hierarchy leads you to a topic "Scanned Documentation" merely select that topic. The next topic should read "Page 1, Page 2,... etc." or "Paper 1 Page 1, Paper 1 Page 2, .... Paper 2 Page 1.... etc. You can select the pages manually, or create a "slide show" under the Utilities option at the top of the screen. The first time the .gif file displays it might be reduced in size. This is a "feature" of current versions of GeoVu that might be improved in the future. If you redisplay the image (by selecting "Search" from the options at the top of the screen, then "Create" from the menu thus pulled down, you can modify the parameter that sets the sampling rate from "n" [usually 2, 3, 4, or 5] to 1). This will give you full resolution display of the scanned documentation. It should be noted that this scanned documentation is a compromise. We originally attempted to use optical character recognition software to convert the scanned documentation to more usable text. However, the technology was too immature at the time of scanning (1992) to use successfully. Indeed, as of this writing (late 1995) the technology is still too immature for convenient application to this problem. Thus, we present the scanned documentation as images. NOTE: Many of the original documents are not copyright, and may be reproduced freely. However, several other documents ARE copyright. The National Geophysical Data Center has obtained permission to reproduce all documents with a valid copyright. However, this permission does not pass automatically to anyone else. Thus, though all of the data on this CD-ROM are unrestricted, much of the scanned documentation (which contains copyright notices) may not be distributed further, without permission of the copyright holder, or without a dontribution made to the Copyright Clearance Center under the rules noted in the individual papers. (Also note that a few documents authored by U. S. Government employees or contractors as part of their work for the Government, had copyrights claimed by the journals that published the papers. Such documents are not subject to copyright, and the copyright claims of said journals have been determined to be meritless.) *MF SCANNED DOCUMENTATION MATTHEWS AND FUNG WETLANDS METHANE Paper 1 Page 1 #\document\ncillary\mf\mfw_001.gif Paper 1 Page 2 #\document\ncillary\mf\mfw_002.gif Paper 1 Page 3 #\document\ncillary\mf\mfw_003.gif Paper 1 Page 4 #\document\ncillary\mf\mfw_004.gif Paper 1 Page 5 #\document\ncillary\mf\mfw_005.gif Paper 1 Page 6 #\document\ncillary\mf\mfw_006.gif Paper 1 Page 7 #\document\ncillary\mf\mfw_007.gif Paper 1 Page 8 #\document\ncillary\mf\mfw_008.gif Paper 1 Page 9 #\document\ncillary\mf\mfw_009.gif Paper 1 Page 10 #\document\ncillary\mf\mfw_010.gif Paper 1 Page 11 #\document\ncillary\mf\mfw_011.gif Paper 1 Page 12 #\document\ncillary\mf\mfw_012.gif Paper 1 Page 13 #\document\ncillary\mf\mfw_013.gif Paper 1 Page 14 #\document\ncillary\mf\mfw_014.gif Paper 1 Page 15 #\document\ncillary\mf\mfw_015.gif Paper 1 Page 16 #\document\ncillary\mf\mfw_016.gif Paper 1 Page 17 #\document\ncillary\mf\mfw_017.gif Paper 1 Page 18 #\document\ncillary\mf\mfw_018.gif Paper 1 Page 19 #\document\ncillary\mf\mfw_019.gif Paper 1 Page 20 #\document\ncillary\mf\mfw_020.gif Paper 1 Page 21 #\document\ncillary\mf\mfw_021.gif Paper 2 Page 1 #\document\ncillary\mf\mfw_001.gif Paper 2 Page 2 #\document\ncillary\mf\mfw_002.gif Paper 2 Page 3 #\document\ncillary\mf\mfw_003.gif Paper 2 Page 4 #\document\ncillary\mf\mfw_004.gif Paper 2 Page 5 #\document\ncillary\mf\mfw_005.gif Paper 2 Page 6 #\document\ncillary\mf\mfw_006.gif Paper 2 Page 7 #\document\ncillary\mf\mfw_007.gif Paper 2 Page 8 #\document\ncillary\mf\mfw_008.gif Paper 2 Page 9 #\document\ncillary\mf\mfw_009.gif Paper 2 Page 10 #\document\ncillary\mf\mfw_010.gif Paper 2 Page 11 #\document\ncillary\mf\mfw_011.gif Paper 2 Page 12 #\document\ncillary\mf\mfw_012.gif Paper 2 Page 13 #\document\ncillary\mf\mfw_013.gif Paper 2 Page 14 #\document\ncillary\mf\mfw_014.gif Paper 2 Page 15 #\document\ncillary\mf\mfw_015.gif Paper 2 Page 16 #\document\ncillary\mf\mfw_016.gif Paper 2 Page 17 #\document\ncillary\mf\mfw_017.gif Paper 2 Page 18 #\document\ncillary\mf\mfw_018.gif Paper 2 Page 19 #\document\ncillary\mf\mfw_019.gif Paper 2 Page 20 #\document\ncillary\mf\mfw_020.gif Paper 2 Page 21 #\document\ncillary\mf\mfw_021.gif Paper 2 Page 22 #\document\ncillary\mf\mfw_022.gif Paper 2 Page 23 #\document\ncillary\mf\mfw_023.gif Paper 2 Page 24 #\document\ncillary\mf\mfw_024.gif Paper 2 Page 25 #\document\ncillary\mf\mfw_025.gif Paper 2 Page 26 #\document\ncillary\mf\mfw_026.gif
