[FEATURE REQUEST] 1-year Transport Tracer benchmark

[lizziel]

The GEOS-Chem Transport Tracer benchmark code is currently written in IDL and stored at https://bitbucket.org/gcst/gc_1yr_rnpbbepasv_benchmark. The same functionality should be added to GCPy as needed to retire the dependency on IDL.

We have now modified GCPy so that you can create benchmark plots & budgets for either the full-chem or TransportTracers benchmarks.

NOTE: Right now the TransportTracers budget code has to be called separately but further modifications can make it be called from run_1yr_benchmark.py.

We now can plot the following output for the TransportTracersBenchmark:

GCC vs. GCC

1. RnPbBe tracer concentrations
2. Passive tracer concentrations
3. WetLossConv rates (loss of soluble species in convection)
4. WetLossLS rates (loss of soluble species in rainout/washout)
5. Budgets of Pb210, Be7, Be10
6. Budget diagnostics (change of mass after each operation)
7. Strat-trop exchange of Rn, Pb, Be (flux of species from TPCORE across 100hPa)

GCHP vs. GCC

1. RnPbBe tracer concentrations
2. Passive tracer concentrations
3. WetLossConv rates
4. WetLossLS rates
5. Budgets of Pb210, Be7, Be10
6. Budget diagnostics

GCHP vs. GCHP

1. RnPbBe tracer concentrations
2. Passive tracer concentrations
3. WetLossConv rates
4. WetLossLS rates
5. Budgets of Pb210, Be7, Be10
6. Budget diagnostics

Therefore we can close out this issue. We may investigate how to obtain the strat-trop exchange from GCHP in the future.
