  <Summary>
    <Abstract>Records of past temperature, precipitation, and other climate variables derived from paleoclimate proxies.  Parameter keywords describe what was measured in this data set.  Additional summary information can be found in the abstracts of papers listed in the data set citations. 
          STUDY NOTES: A preliminary, broad-scale vegetation map reconstruction for use by archaeologists 
and anthropologists is presented here for the world at the Last Glacial Maximum 
(18,000 BP, but broadly representing the interval from 25,000 to 15,000 BP). 
The global LGM map was produced from a range of literature and map sources, 
and drawn on a GIS with topographic information. Extended coastlines due to LGM 
sea-level drop were obtained using bathymetric information. The map is 
available in image and Geographic Information System (GIS) formats, on a 
global or regional basis.

Accompanying each regional map is a 
bibliography detailing the principal literature sources of evidence on 
Late Quaternary palaeovegetation and climates. The maps presented here are 
merely a preliminary attempt at appraisal of current knowledge and 
opinion, and future updated versions will be produced as more information 
on LGM environments becomes available. Nevertheless, together with the 
accompanying citation summary they should provide a valuable and readily 
accessible source of information on current opinion in the Quaternary 
community. It is also hoped that the maps will themselves act as a 
catalyst for archaeologists to use their own data to contribute to the 
broader climatic/palaeovegetational picture</Abstract>
