Appendix IV LOICZ Typology Database

The LOICZ Typology Database contains an array of parameters and variables providing data for atmospheric, geomorphic, human dimensions, oceanic, terrestrial and river basin conditions at the scale of half-degree resolution. Details may be obtained from the LOICZ Typology web site; metadata available on the web site describe the sources of the global data sets. The database is continuing to expand and the listing below describes data sets available 1 November 2001. (Cont = continuous data; Disc = discrete, or classified data; ScDisc = scaled discrete data, in which the numerical class identifiers are approximately scaled to the range of values contained in that class).
