1 Jan 1998
- 31 Mar 1999 		e62000 5 Oct 2001 Parameterized H2O run Test of interactive water parameterization in the full CTM. This is the same parameterization as used in the full CTM. Used fvDAS winds and 1/1/67 fvCCM H2O initial conditions to test. Level 1 is fixed to saturation with respect to liquid. Levels between level 2 and 70 hPa are capped at saturation with respect to liquid at or above -40C and with respect to ice below -40C (Marti & Mauerberger, '93). Passive transport at and above 70 hPa.

- 31 Mar 1999 		e62001 2 Oct 2001 Parameterized H2O run 2 Test of H2O parameterization for interactive water in the FCTM Used fvDAS winds and 1/1/67 fvGCM H2O initial conditions to test. Fixed first model level to a mixing ratio of .04. Between level 2 and 70 hPa limit H2O to saturation mixing ratio wrt ice (Marti and Mauersberger '93) if temperature below -40C and saturation mixing ratio wrt liquid (Clausius-Clapeyron formulation from Hess) -40C and above. Passive above 70 hPa. Stratosphere very little changed from original Gettelman parameterization, troposphere looks much better.

e630 July 2004 Radioactive tracer run. Twelve tracers each with differing characteristics. (b55_50yr winds) Tracer run using transport with convection using GEOS3 fields. Twelve radioactive tracers, ten tracers with exponential decay rates, half-lives of 25.3, 75.9, 126.5, 253,506, 759, 1265, 1771, 2530, 3289 days respectively. One oscillating tracer with a one year period, and a pulse tracer set for one day. All have sources (value one expect for oscillating tracer(2-4))in the tropics (15S-15N) at the tropical tropopause.
