# Data: "MJO simulated by a hybrid GCM" (GRL)

Model output and observations for the HyCAM vs CAM5 vs observations MJO
study, as ORIGINAL variables (daily model history fields and the
observational reference products; no filtered or derived quantities).
The figures and the full analysis code (anomaly, two-harmonic
climatology, 20-100-day Lanczos filtering, regressions, Wheeler-Hendon
index, wkSpaceTime spectra, and the plot scripts) are in the Zenodo
record accompanying the paper; running that code on the files below
regenerates every intermediate product and figure.

## model_output/

AMIP simulations (FAMIPC5, f19 1.9x2.5, CAM5 physics), 1991-2005 daily
means, noleap calendar.  HyCAM is the neural-network hybrid CAM5; CAM5
is the standard model.

| File | Contents |
|---|---|
| `{HyCAM,CAM5}_daily.nc` (1.5 GB each) | Daily 2-D fields: PRECT, FLUT (OLR), U850, V850, U200 |
| `{HyCAM,CAM5}_band30_daily3d.nc` (50 GB each) | Daily 3-D fields, 30S-30N, 30 hybrid levels: T, Q, U, V, OMEGA, the physics tendencies (PTTEND, PTEQ, DTCOND, DCQ, QRS, QRL) and the model advection diagnostics (HAQ, VAQ, HADVT, VAT), plus PS and the hybrid-coordinate coefficients |

| `trmm/3B42_daily_1998_2010.nc` | TRMM 3B42 v7 daily precipitation regridded to the model 1.9x2.5 grid |
| `trmm/trmm_pcp_daily_ncl.nc` | The same TRMM precipitation on the model belt grid, gap-filled, as input to the wkSpaceTime spectra |
| `noaa_olr/olr.day.mean.1990-2005.nc` | NOAA interpolated daily OLR |
| `era5/daily_raw.nc` | ERA5 daily single-level and 850-hPa fields used for the climatology and life-cycle figures |
| `era5/era5_tp_daily_ncl.nc` | ERA5 daily total precipitation for the spectra |

ERA5 daily fields on the 37 pressure levels (used for the ERA5 heating,
moisture-budget and state cross-sections) are not mirrored here; they
are obtainable from the Copernicus Climate Data Store (single request,
1991-2005 daily, 30S-30N suffices).
