Status of ICWG Cloud Height Intercomparisons
The International Cloud Working Group (ICWG) and the IWWG maintain a shared activity of assessing the cloud height products from the operational agencies for their use in assigning heights to derived motion wind vectors. This presentation will summarize the current state of the height algorithms from the ICWG participants and their plans for development. The ICWG has implemented a best-fit analysis that uses wind fields from the IWWG participants and NWP models to derive wind vector height estimates. These are then compared to the products from the agencies which participate in the ICWG intercomparisons. This analysis will be applied to the Golden Days shared among the IWWG and ICWG. The analysis will attempt to establish the level of agreement among the algorithms and identify scenarios where their performance may negatively impact the derived motion winds application.
