Improving severe weather forecasting with the new Vaisala DIAL atmospheric profiler
It is known that high-resolution humidity profiles within the boundary layer are essential parameters for severe weather nowcasting. Vaisala's brand-new Vaisala broadband differential absorption lidar (DIAL) is targeted to help enhance numerical weather prediction (NWP) to provide more accurate severe weather and flood predictions. This requires data products not typically found in ceilometers. Our aim is to provide needed information with real-life examples of how the Vaisala DIAL will serve NWP data assimilation in the future. This will enable DIALs to be used more widely in large networks and have an impact on more accurate mesoscale weather forecasting.
