Book Description
This document describes a data base containing daily observations of maximum and minimum temperature and precipitation amounts from 138 US stations. These stations are a specially chosen subset of the 1219-station US Historical Climatology Network (HCN), compiled by the National Climatic Data Center (Asheville, North Carolina). The daily data network (herein referred to as the HCN/D) consists of stations considered to be the best of those from the HCN, selected to provide reasonably homogeneous spatial coverage of the contiguous US after considering the temporal homogeneity of each station's observing times, instrument types/positions, and surroundings. The data for each station extend through 1987, and most station records are complete for at least 80 years. The daily resolution of these data lends maximum flexibility for studies attempting to detect and monitor long-term climatic changes on a regional scale. Studies using daily data may be able to detect changes in regional climate that would not be apparent from analysis of the more commonly used monthly temperature and precipitation data. Such studies may include analyses of trends in maximum/minimum temperatures, temperature extremes, daily temperature range, precipitation ''event size'' frequency, and the magnitude and duration of wet and dry periods. Other applications of the data include planning and risk assessment in areas such as agriculture, natural resource exploration, and construction. This document describes how the stations in the HCN/D were selected, defines limitations and restrictions of the data, describes the format and contents of the magnetic tape, and provides reprints of literature pertinent to the collection and application of daily climate data.

Book Description
Are extreme weather events becoming more common? How do extreme weather events impact society? These are critical questions that must be examined as we confront the possibility that the world will experience a change in climate over the next century. Much of the research in climatology over the past decade has focused on potential changes in long- term averages of temperature, precipitation and other factors. However, it is becoming increasingly clear that changes in average values will be accompanied by changes in extreme events. Furthermore, extreme weather events will impact society to a greater extent as people around the world continue to locate in more hazard-prone areas such as coastal zones. This book represents a major step forwards in developing a comprehensive set of information about changes in extreme events by providing a review of the problems in data availability, quality and analysis that make deriving a clear picture of world-wide changes in extreme events so difficult. Audience: The book is intended for policy-makers, professionals, graduate students and others interested in learning how extreme weather events have changed, and how they impact society both now and in the future.

Book Description
"While climatological observations have been steadily accumulating for the last quarter of a century, the general results are inaccessible, not only to the general public but also to tho great majority of students and investigators interested in the advancement of scientific agriculture in the United States. The work herewith aims to present in form for ready reference comparative climatic statistics for the different portions of the United States, accompanied by explanatory charts and text. The charts and text figures are necessary to a proper understanding of the text"--Letter of transmittal.
