A quality assessment of daily manual snowfall data has been undertaken for all U.S. long-term stations and their suitability for climate research. The assessment utilized expert judgment on the quality of each station. Through this process, the authors have identified a set of stations believed to be suitable for analysis of trends. Since the 1920s,(More)
Temporal variability in the occurrence of the most extreme snowfall years, both those with abundant snowfall amounts and those lacking snowfall, was examined using a set of 440 quality-controlled, homogenous U.S. snowfall records. The frequencies with which winter-centered annual snowfall totals exceeded the 90th and 10th percentile thresholds at individual(More)
There is an increasing interest in examining long-term trends in measures of snow climatology. An examination of the U.S. daily snowfall records for 1900–2004 revealed numerous apparent inconsistencies. For example, long-term snowfall trends among neighboring lake-effect stations differ greatly from insignificant to ϩ100% century Ϫ1. Internal(More)
[1] Recent photographic documentation of poor siting conditions at stations in the U.S. Historical Climatology Network (USHCN) has led to questions regarding the reliability of surface temperature trends over the conterminous United States (CONUS). To evaluate the potential impact of poor siting/instrument exposure on CONUS temperatures, trends derived from(More)

Front Cover: The left map shows mean annual precipitation in inches across Illinois during the period 1971-2000. The right map shows a calculation of the amount of annual precipitation that would be expected to occur during severe drought with a 200-year return period, based on the records at 74 stations.

The provision of adequate and secure supplies of clean water at reasonable cost is a cornerstone of social and economic development and national security. Major droughts have occurred in the past and will occur again in the future. Such droughts have two major impacts on small community water systems: water supply is reduced (surface waters and shallow(More)
