MVT allows the user to compare two fields with a high degree of interaction; AutoMVT allows the comparison of several fields with limited interaction. Both tools are based upon the same underlying software, so the results from one tool are the same as those from the other. AutoMVT "Summary" Screen Click to Enlarge AuotMVT is a web interface to the Mesoscale Verification Tool. The user may select a range of dates for comparison as well as search several forecasts of various parameters. Since the volume of data can be massive the verification is performed asynchronously. When complete the user receives email notification which includes a URL to check the results. AutoMVT "Details" Screen Click to Enlarge
