LOGICast™ is a software system that is designed to address the difficult problem of producing high quality weather forecasts at locations where observations are not available. Accurate forecasts at remote locations are used to drive many user–specific applications such as road temperature forecasts along an entire roadway, or soil temperature forecasts for agriculture.

LOGICast™ combines numerical weather prediction (NWP) model forecasts, statistically refined point forecasts, and climatology to interpolate forecast data to a high resolution grid. Applications using LOGICast™ typically use 4–km grid cell resolution. Higher resolution grids may be appropriate in regions of rapidly changing topography.

To generate these forecasts, Logicast starts with model data from a NWP model(s) and then downscales those data onto the target grid using a sophisticated climatological difference interpolation scheme. Finally, this downscaled forecast is corrected to match a statistically optimized forecast generated at a set of observation points.

LOGICast™ technology is ideality suited for downstream systems and users that require precision location–based forecasts. LOGICast™ is a licensed technology of the UCAR Foundation.
