HyCAM.ftorch.2d — Atmospheric Climatology vs Observations

Model = HyCAM.ftorch.2d.seq2.seed.333.nl.22.128.ep.100 (FTorch ResCu neural-network super-parameterization, F2000 compset). Climatology computed over model years 2-10 (spin-up year 1 removed).

1. AMWG Diagnostics Package — model vs observations

The full NCAR AMWG climatology package (v140804): ~1000 plots across zonal means (set 3), vertical contours (set 4), lat-lon maps & vectors (set 5/6), polar (set 7), annual cycle (set 8), and DJF-JJA (set 9), each compared against its standard observational reference (NCEP, ERA-Interim, ERA40, MERRA, JRA-25, GPCP, TRMM, CERES, ERBE, ISCCP, ...).

2. Comparison with ERA5 & IMERG

Added modern references using the f19-regridded obs in /pscratch/sd/h/hanyilun/obs: ERA5 reanalysis (2-m temperature, precipitable water, and T/U/V zonal-mean cross-sections) and IMERG precipitation. Model / obs / bias panels with area-weighted RMSE, for DJF, JJA, and annual.
