Abstract: Partial-duration maximum precipitation series from Historical Climatology Network stations are used as a basis for assessing trends in extreme-precipitation recurrence-interval amounts. Two types of time series are analyzed: ...

Abstract: Simulated annual temperature series are used to compare seven homogenization procedures. The two that employ likelihood ratio tests routinely outperform other methods in their ability to identify modest (0.33°C; 0.6 standard ...

Abstract: A method to infer the observation time of a station at annual resolution is developed and tested at stations in the United States. The procedure is based on a tendency for the percentiles of the monthly distribution of ...

Abstract: From 4 through 10 January 1998 a severe ice storm impacted northern New York and New England. Liquid?equivalent precipitation totals, which fell exclusively as freezing rain, reached as high as 11 cm at some observing sites ...

Abstract: A procedure to infer time of observation based on day?to?day temperature variations is refined and applied to the 1060?station daily Historical Climatology Network (HCN), creating a set of ersatz observation time metadata. ...

Abstract: The quality of hourly wind speed and direction observations from 41 northeastern U.S. first-order weather stations is evaluated with regard to the recognition of individual observations that are either obviously in error ...

Abstract: Changes in the annual number of daily maximum and minimum temperature threshold exceedences between 1951 and 1993 are assessed at a network of 22 primarily rural sites in the northeastern United States. After adjusting the ...

Abstract: Hourly dewpoint temperature data for the 1951?2006 period at 10 stations in the contiguous United States were investigated to determine if inhomogeneities in their records could be detected. At least three instrument changes ...
