DigiCORA METGRAPH by Vaisala is a software application for visualizing and analyzing upper‑air sounding data collected with DigiCORA systems and Vaisala radiosondes. It turns raw observations into clear, actionable products by displaying thermodynamic profiles, wind barbs, and hodographs, and by generating standard diagrams such as the Skew‑T/log‑P. The software calculates key atmospheric indices, supports basic quality control and annotation, and produces presentation-ready plots and reports.
Designed for operational forecasting, aviation weather support, and research, DigiCORA METGRAPH helps users quickly interpret temperature, humidity, and wind structure through the depth of the atmosphere. It supports comparison of multiple soundings, trend assessment, and convenient export of graphics and data to fit into existing workflows.
DigiCORA METGRAPH is developed by Vaisala. The most popular version of this product among our users is 3.6.
