摘要

已经开发了各种利用气象数据估算蒸散量的经验方法。然而，目前还没有基于用户提供的每日数据来估计每日蒸散量的在线工具。在这里，我们介绍ETCalc(https://etcalc.hydrotools.tech)，一个免费、独特的在线工具，集成了八种方法（即Penman-Monteith、Thornthwaite、Blaney–Criddle、Turc、Priestley–Taylor、Hargreaves、Jensen–Haise和Abtew），用于估计每日潜在蒸散量、参考蒸散量，并通过使用用户定义的作物（或覆盖物）系数来估计每日实际蒸散量，基于用户提供的每日气象数据。ETCalc是为了响应加拿大联邦政府鼓励更容易和开放地获取科学的努力而开发的，适用于任何有基本气象数据的地区，因此其适用性不限于特定的地理区域。通过简化的界面，ETCalc允许上传用户提供的数据，对输入和输出数据进行表格和图形检查，以及导出输出数据和相关元数据。ETCalc的使用以加拿大爱德华王子岛夏洛特敦的10年每日气象数据为例，用于比较每种ETCalc方法的输出和计算降水量不足。

Development and Application of ETCalc, a Unique Online Tool for Estimation of Daily Evapotranspiration

ABSTRACT Various empirical methods that use meteorological data have been developed for estimating evapotranspiration. However, there are currently no online tools available for the estimation of daily evapotranspiration based on user-provided daily data. Here, we introduce ETCalc (https://etcalc.hydrotools.tech), a free, unique online tool that integrates eight methods (i.e. Penman-Monteith, Thornthwaite, Blaney – Criddle, Turc, Priestley – Taylor, Hargreaves, Jensen – Haise and Abtew) for estimation of daily potential evapotranspiration, reference evapotranspiration and, by employing user-defined crop (or cover) coefficients, daily actual evapotranspiration, based on user-provided daily meteorological data. ETCalc has been developed in response to the effort of the Canadian federal government to encourage easier and open access to science and is applicable to any area for which basic meteorological data are available and hence, its suitability is not restricted to particular geographical areas. Through a streamlined interface, ETCalc allows for uploading of user-provided data, tabular and graphical inspection of the input and output data, as well as export of the output data and of the associated metadata. The use of ETCalc is exemplified using 10-year daily meteorological data from Charlottetown, Prince Edward Island, Canada for comparing the output from each of the ETCalc methods and for the calculation of the precipitation deficit.

期刊介绍： Atmosphere-Ocean is the principal scientific journal of the Canadian Meteorological and Oceanographic Society (CMOS). It contains results of original research, survey articles, notes and comments on published papers in all fields of the atmospheric, oceanographic and hydrological sciences. Arctic, coastal and mid- to high-latitude regions are areas of particular interest. Applied or fundamental research contributions in English or French on the following topics are welcomed: climate and climatology; observation technology, remote sensing; forecasting, modelling, numerical methods; physics, dynamics, chemistry, biogeochemistry; boundary layers, pollution, aerosols; circulation, cloud physics, hydrology, air-sea interactions; waves, ice, energy exchange and related environmental topics.
