− | === Benchmark overview ===
| |
− |
| |
− | 1-year Rn-Pb-Be benchmark simulations are completed at the request of the Transport Working Group or whenever an update is introduced into the code that will impact transport and/or wet deposition. Each of these benchmarks involve a 4-year spinup period, followed by the 1-year run used for evaluation.

Sink
|
Purpose
|
Rn222
|
Radon-222 isotope
|
|
- Half-life of 3.83 days (Liu at al., 2001).

- EXP( -ΔT * 2.097d-6 )
|
Used to evaluate convection over land and strat-trop exchange
|
Pb210
|
Lead-210 isotope
|
- Radioactive decay from Rn222 according to the exponential law:

|
|
Used to evaluate strat-trop exchange
|
Be7
|
Beryllium-7 isotope
|
- Produced by cosmic rays as described in Lal and B. Peters, 1967
- Plus the following modifications from Liu et al. (2001):
- Replace data at (0 hPa altitude, 70°S latitude) following Koch (1996):
- old value = 3000 disintegrations/g air/s
- new value = 1900 disintegrations/g air/s
- The original Lal & Peters data ended at 70°S
- Copy the data values at 70°S to 80°S and 90°S at all levels
