Information GMBA mountain definition_V1.1 ------------------------------------------- General: The file "GMBA mountain definition_V1.1.txt" provides ruggedness values for individual cells as calculated in Körner et al. 2011 in a text format. The files required to work with the ruggedness data in a GIS software are included in the "GMBA mountain definition_V1.1(GIS)" folder. This folder includes the required .shp, she, prj, dbf, and .tif files. Version: V1.1 (changes to V1.0 consist of the removal of mistakes in the Tvzcode Labels below and a new .tif files for the climatic belts and the mountain definition. Only the labeling changed; the raw data did not change.) Grid cell size: 0.04166666 decimal degrees (2.5 Arc minute; 2 minutes 30 seconds), 30' grid IMPORTANT NOTE: the abstract to Körner et al. mistakenly mentions an 0.5' resolution. Correct information is available in the main text. Column Labels in GMBA mountain definition_V1.1.txt Latitude: in degrees and decimal fractions of degrees Longitude: in degrees and decimal fractions of degrees Ruggedness: maximal elevational distance between neighbour cells tvzcode:label for "thermic vegetation zone" Tvzcode Labels in GMBA mountain definition_V1.1.txt -9: not available 1: nival (growing season < 10 days; season mean temperature < 3.5 degrees C) 2: upper alpine zone (growing season between 10 and 54 days; season mean temperature < 3.5 degrees C) 3: lower alpine zone (growing season < 94 days or season mean temperature < 6.4 degrees C) 4: upper montane zone (growing season >= 94 days and season mean temperature between 6.4 and 10.0 degrees C) 5: lower montane zone (growing season >= 94 days and season mean temperature between 10.0 and 15.0 degrees C) 6: warm zone with possible freezing (growing season >= 94 days and season mean temperature > 15.0 degrees C ) 7: zone with perpetual warm conditions, no freezing (growing season >= 94 days and season mean temperature > 15.0 degrees C) How to cite When using the GMBA ruggedness data, please cite: Körner C, Paulsen J, Spehn E (2011) A definition of mountains and their bioclimatic belts for global comparisons of biodiversity data.
