Book Description
The objective of this study was to demonstrate the effectiveness of a lightning detection network in providing a real-time data base from which automated observations of thunderstorms and lightning in the vicinity of an air base can be derived. A direction-finding cloud-to-ground lightning detection network (LDN) operated by the State Univ. of New York at Albany provided a data base of CG lightning locations in the northeastern United States for July-August, 1986. Copies of the original weather observation forms from 25 AF weather stations in the same area and time period provided a data base of thunderstorm and lightning observations for comparison. The lightning data base was analyzed for strike events located within 15 nm of each weather station. If the 15 minute period lapsed without another strike, the event was ended. Events were categorized as single- or multiple-strike events and the duration of the events tabulated. The weather observation data base was analyzed for thunderstorm events. The beginning time, ending time and duration of the events were tabulated as well as the type of lightning that was reported with each observation. Chronological comparison of the two data bases, using the weather observation data base as 'ground truth', generated 4 X 4 contingency tables of the combinations of thunderstorm-lightning events. Four parameters were derived from the statistical evaluation of the contingency tables: 1) Probability of detection; 2) False alarm rate; 3) Missed threat rate; and 4) Critical success index. Two case studies were performed with the lightning strike data base.

Book Description
Climate Observations: Data Quality Control and Time Series Homogenization pulls together the different phases of the production of high-quality climatic datasets, allowing interested readers to obtain a coherent picture on the complexity and importance of this task. There are several new methods of time series homogenization, each very complex and fast developing. The thematic discussion of the production of high quality climatic datasets provides the opportunity to reduce errors, including the careful installation of meteorological instruments, the application of strict observing rules and inspections, and the use of sophistically developed statistical software to detect and remove errors or biases. This book is intended for professionals working on climate data management at the national meteorological services, for the users of observed climatic data, and for students and researchers studying atmospheric and climate science. Members of the Royal Meteorological Society are eligible for a 35% discount on all Developments in Weather and Climate Science series titles. See the RMetS member dashboard for the discount code. - Describes the research tasks and tools for which the reliability and accuracy of climatic data is particularly important - Includes case studies to provide real-world context to the research presented in the book - Features benchmark datasets that have been used for testing the stable operation and efficiency of homogenization methods - Explains the use of semiautomatic quality control software, recently developed effective homogenization methods, their testing, and related new concepts and statistical tools
