HyCAM.ftorch.2d — Climatology vs ERA5 & IMERG (model years 2-10)

Each panel = model (top), obs (middle), model − obs bias (bottom, with area-weighted RMSE). ERA5 reanalysis (1990-2010 monthly means, regridded to the model f19 grid) for temperature/humidity/winds; IMERG (2000-2010) for precipitation. Seasonal climatology: DJF, JJA, annual. ← back to AMWG vs-obs overview
