Northern Hemisphere Cyclone Locations and Characteristics from NCEP/NCAR Reanalysis Data

This data set comprises a 58-year record of daily extratropical cyclone statistics computed for the Northern Hemisphere. The data is available here: doi.org/10.5067/XEPCLZKPAJBK. Cyclone locations and characteristics were obtained by applying the updated Serreze (1997) algorithm to daily Sea Level Pressure (SLP) data at six-hour intervals (Serreze and Barrett 2008). The SLP source data are part of the National Centers for Environmental Prediction (NCEP) and National Center for Atmospheric Research (NCAR) Reanalysis data set, an assimilation of various atmospheric data collected by a wide variety of sensors within a global weather model.
