28

o3

Mole Fraction of O3


O3

o3 = O3



interpolated to 19 pressure levels.

Philip Cameron-Smith (Unlicensed): Yes, the E3SM variable O3 is what is wanted here.  However, it would be good to note somehow that "Stratospheric ozone is prognostic, and tropospheric ozone follows the input4mips prescribed concentrations."

For v3 output, both FSUTOA and FSUTOAC are removed. This PR is to update formula to use available variables, i.e., rsut = SOLIN - FSNTOA, and rsutcs = SOLIN - FSNTOAC

tasmax

Daily Maximum Near-Surface Air Temperature


TREFHTMX

TREFMXAV (available on h0 starting v2)



J. Zhang

Update  

The monthly averaged daily mean max/min surface temperature are now standard output on h0 starting v2.


We cannot use monthly h0 output for this. But the necessary data is in daily h1 files. We would have to create time series of monthly averages from these daily files. double checked that TREFHTMX and TREFHTMN saved to h1 have the same values as TREFHT. Checked code in cam_diagnostics.F90, TREFMNAV and TREFMXAV should be the correct field to output. Unfortunately, those high frequency data saved are not useful
