Research in 1992--93, the second year of the project, involved, inter alia, the following topics: continuation of studies of proxy climatic records to try to extend the record of large-scale climatic conditions back into previous centuries, and to determine if there are reliable regional analogs for larger scale climatic fluctuations; examination of indices of long-term climatic variability to determine if climate has become more, or less, variable over time. This involves studies of both instrumental and proxy data sets for sites throughout the world; Continuation of studies of mid-winter polar boundary layer climate as a possible indicator of greenhouse gas-induced climate changes; documentation of the linkages between observed temperature and precipitation changes on regional space scales and changes in large-scale atmospheric circulation patterns; regridding of global temperature anomalies using an equidistant grid, optimal interpolation scheme, and stratification of data by extent of urbanization at each station, then recomputation of regional and hemispheric temperature trends. Significant progress has been made in all of these areas. In the report, we summarize results of the work accomplished.
