Validation Toolbox (Performance Metrics for Remote Sensing Data and Climate Model Simulations)

A simple and easy to use Validation Toolbox (MATLAB source code) that can be used for evaluation of gridded data including satellite observations, reanalysis data, and weather and climate model simulations. In addition to the commonly used categorical indices, the toolbox includes the Volumetric Hit Index (VHI), Volumetric False Alarm Ration (VFAR), Volumetric Missed Index (VMI), and Volumetric Critical Success Index introduced in:
