Data Used in the Book
Hydrologic data discussed in this book include flow, rainfall, temperature, tree-ring data and Palmer’s Drought Severity Index (PDSI) Series. Flow data are obtained from the United States Geological Survey (USGS, 1992) and Earth Info (1993) data bases. Both rainfall and temperature data are obtained as two different sets. One set is obtained from the Historical Climatology Network (HCN) database (Nelson and Boden, 1993) for individual stations. Another set is obtained from the National Climatic Data Center (NCDC) database (NCDC, 1991) for state divisions. Precipitation and temperature data are also taken from Earth Info (1993) database. Tree-ring data are obtained from the National Oceanic and Atmospheric Administration database (NOAA, 1997). The PDSI data are obtained from National Climatic Data Center, NOAA.
