Three dimensional Adaptive Resolution (AR) is an advanced feature newly developed in the IDV. When loading a 3D parameter from high resolution model output, such as 3km high resolution rapid refresh (HRRR), with AR turned on, the IDV detects the resolution of the view window, calculates the data sampling factors dynamically in each dimension, and loads a sufficient amount of the data to generate images at the correct resolution. Furthermore, a rubber band box interface allows the user to zoom in/out or change the projection, forcing the IDV to recalculate the data sampling factors and get higher/lower resolution data. The IDV users can interactively slice, dice, and probe the data, creating 3-dimensional view of the datasets without worrying about the performance and memory usage. Combining with the client server architecture, this new feature allows the IDV users to effectively investigate the details of weather phenomena and to better understand the underlying dynamics and physics.
