Hourly computed potential evapotranspiration in thousandths of an inch, January 1, 1948 - September 30, 2016

The text file PET.txt contains hourly data from January 1, 1948, to September 30, 2016. Daily potential evapotranspiration (PET) in thousandths of an inch is computed from average daily air temperature in degrees Fahrenheit (°F), average daily dewpoint temperature in degrees Fahrenheit (°F), daily total wind movement in miles (mi), and daily total solar radiation in Langleys per day (Lg/d) and disaggregated to hourly PET in thousandths of an inch using the Fortran program LXPET (Murphy, 2005).

文本文件PET.txt包含1948年1月1日至2016年9月30日的逐小时数据。千分之一英寸单位的逐日潜在蒸散量（potential evapotranspiration，PET）由日平均空气温度（华氏度，°F）、日平均露点温度（华氏度，°F）、日总风程（英里，mi）以及日总太阳辐射（兰利/日，Lg/d）计算得到，并借助Fortran程序LXPET（Murphy，2005）将其分解为同样以千分之一英寸为单位的逐小时PET。参考文献：Murphy, E.A., 2005, 《LXPET（Lamoreux潜在蒸散量）程序与WDMUtil（流域数据管理工具，Watershed Data Management Utility）程序计算的潜在蒸散量对比》：美国地质调查局公开文件报告2005-1020，共20页，https://pubs.er.usgs.gov/publication/ofr20051020.
