HydroClimATe: Hydrologic and Climatic Analysis Toolkit
Overview of HydroClimATe
The Hydrologic and Climatic Analysis Toolkit (HydroClimATe) is a computer program for assessing the relations among variable climatic and hydrologic time-series data.
HydroClimATe automates the use of several objective methods for assessing relations among one or more sets of data that vary in time and space with climate variability and variability in hydrologic time-series data. Although the software was written for the purpose of identifying relations between hydrologic and climatic time series, the available tools and methods can be applied to many other types of time series generated by physical, biological, economic, or social processes. The methods include
The software combines these methods in order to provide a set of analysis tools that can be readily implemented for processing hydrologic time-series data.
