1-year benchmarks
v11-01b-RnPbBe
A 1-year Rn-Pb-Be simulation was performed using GEOS-Chem v11-01b. The simulation utilized 4° x 5° GEOS-FP met fields for the year 2013, with a 4-year spinup. For comparison of the Pb-210 and Be-7 budgets to previous versions, please see the following posts on the Rn-Pb-Be simulation wiki page:

Requires further investigation: | July 30, 2015 update: A moisture signature is observed in CO2 concentrations during carbon simulations with zero emissions and constant 370 ppm initial conditions. The moisture signature is expected for wet mixing ratio (v/v total air) but not dry mixing ratio (v/v dry air). This issue is currently under investigation. |
