The Atmosphere Model Working Group (AMWG) Diagnostics Framework (ADF) is an automated diagnostic package written in Python, aimed to be used to evaluate and benchmark simulation output from CESM. Here, we describe diagnostics associated with atmospheric chemistry.

The ADF package can be downloaded at https://github.com/NCAR/ADF

Detailed instructions on how to use it can be found here: https://github.com/NCAR/ADF/wiki

Instructions to use the chemistry evaluation are being developed here: Using chemistry diagnostics with CESM

Our current atmospheric chemistry diagnostic development plans/wishlist (view on GitHub: https://github.com/NCAR/ADF/issues/237) are:

DiagnosticExample Plot/ResultGithub Issue

1. Chemistry/Aerosol budget Tables

Tables / Chemistry of ANN global budgets

https://github.com/NCAR/ADF/issues/236

To do: check against NCL script for correct calculations

2. Zonal Average comparisons between model runs.

Vertical Contour Plots contour plots of DJF, MAM, JJA, SON and ANN zonal means

List of species to evaluate: TBD



3. Ozone climatology comparison to observations

Profiles, seasonal cycles and Taylor diagrams

https://github.com/NCAR/ADF/issues/281

To do: troubleshooting Taylor diagrams – fix correlation analysis

4. Column comparison to satellite observations

Lat/lon comparisons for
(a) MOPITT carbon monoxide
(b) OMI/MLS ozone
(c) MODIS aerosol optical depth

(a) CO: https://github.com/NCAR/ADF/issues/235

(b) O3: https://github.com/NCAR/ADF/issues/242

(c) AOD: https://github.com/NCAR/ADF/issues/302

5. Vertical profile comparisons to observations

(a) NOAA aircraft campaigns


6. Surface comparisons to observations

(a) IMPROVE network


7.  Water vapor tape recorder

https://github.com/NCAR/ADF/issues/332

To do: Adjust default color table so that the upper end of the table saturates at 4 or 5 e-6 kg/kg instead of 3.

8.  Composition difference plots

https://github.com/NCAR/ADF/issues/331

To do: Change variable to % difference

WACCM ADF Goals (based on these comparisons https://github.com/NCAR/wawg_dev/issues/2):

  1. QBO
  2. Zonal Mean U winds and Transform Eulerian Mean (TEM) of winds
  3.  Water Vapor (tape recorder) and temperature time series at 100 hPa in the tropics (compare with MLS) (#7 above)
  4. Temperature: NH Polar 
  5. Temperature: SH Polar
  6. Temperature: Dec Zonal Mean (against MERRA and SABER)
  7. Temperature: June Zonal Mean (against MERRA and SABER)
  8. Ozone diagnostics for lower stratosphere (ozone hole)
