Description:
co2 unit test runs

XML: /net/jgj/perth/ESM2.1/rts/ESM2.1U_Control-1860_co2units_sep072008.xml

All tests run with same IC:

no qco2 in canopy.res.nc
atm co2 286e-6 dvmr comverted to moist mmr using Q

Convection turned on for all tests

1) Baseline

co2 prescribed at 286e-6 (land/ocean/radn see 286e-6)
co2 data overrides for land and ocn (286e-6)
qco2 is prescribed (286e-6)


• monthly output from year 1: /archive/jgj/perth/ESM2.1/co2_units_sep072008/ESM2.1U_Control-1860_co2units_baseline/history
• every timestep (subset) from year 1: /archive/jgj/perth/ESM2.1/co2_units_sep072008/ESM2.1U_Control-1860_co2units_baseline_jan/history

2) Free up co2 on land only, radn sees 286e-6

co2 data override for ocean (286e-6)
qco2 is interactive


• monthly output from year 1: /archive/jgj/perth/ESM2.1/co2_units_sep072008/ESM2.1U_Control-1860_co2units_free_lnd_only/history

3) Free up co2 on ocean only, radn sees 286e-6

co2 data override for land (286e-6)
qco2 is prescribed (286e-6)


• monthly output from year 1: /archive/jgj/perth/ESM2.1/co2_units_sep072008/ESM2.1U_Control-1860_co2units_free_ocn_only/history

4) Free up co2 on land and ocean, radn sees 286e-6

No co2 data overrides on land or ocean
qco2 is interactive

5) Free up co2 on land, ocean, and radn

No co2 data overrides on land or ocean, radn is free (predicted).
qco2 is interactive


• monthly output from year 1: /archive/jgj/perth/ESM2.1/co2_units_sep072008/ESM2.1U_Control-1860_co2units_free_lndocnrad/history

6) Turn on co2 restoring in freed up land and ocean expt, radn sees 286e-6

NOTE: co2 is restored for all levels, restoring time is 1 year.
Compare this run to (1) where data overrides are used to prescribe co2.
No co2 data overrides on land or ocean

7) Test: turn on co2 restoring, free ocn, but qco2 is prescribed, radn sees 286e-6

NOTE: co2 is restored for all levels, restoring time is 1 year.
No co2 data overrides on land or ocean
qco2 is prescribed (286e-6)
