hi there, GRAF is up & running since 2019, and running under P9 Servers with their GPUs.
GRAF incorporates the latest-generation global weather model, in the specific the Model for Predictions Across Scales which was developed by NCAR in conjunction with the Los Alamos National Laboratory.
At the moment all the forecast data inlcuded in The Weather Company APIs and coming as layers on Environmental Intelligence Suite are coming from GRAF.
