2	!.. This subroutine computes the moisture tendencies of water vapor,
3	!.. cloud droplets, rain, cloud ice (pristine), snow, and graupel.
4	!.. Prior to WRFv2.2 this code was based on Reisner et al (1998), but
5	!.. few of those pieces remain. A complete description is now found in
6	!.. Thompson, G., P. R. Field, R. M. Rasmussen, and W. D. Hall, 2008:
7	!.. Explicit Forecasts of winter precipitation using an improved bulk
8	!.. microphysics scheme. Part II: Implementation of a new snow
9	!.. parameterization. Mon. Wea. Rev., 136, 5095-5115.
10	!.. Prior to WRFv3.1, this code was single-moment rain prediction as
11	!.. described in the reference above, but in v3.1 and higher, the
12	!.. scheme is two-moment rain (predicted rain number concentration).
13	!..
14	!.. Most importantly, users may wish to modify the prescribed number of
15	!.. cloud droplets (Nt_c; see guidelines mentioned below). Otherwise,
16	!.. users may alter the rain and graupel size distribution parameters
17	!.. to use exponential (Marshal-Palmer) or generalized gamma shape.
18	!.. The snow field assumes a combination of two gamma functions (from
19	!.. Field et al. 2005) and would require significant modifications
20	!.. throughout the entire code to alter its shape as well as accretion
21	!.. rates. Users may also alter the constants used for density of rain,
22	!.. graupel, ice, and snow, but the latter is not constant when using
23	!.. Paul Field's snow distribution and moments methods. Other values
24	!.. users can modify include the constants for mass and/or velocity
25	!.. power law relations and assumed capacitances used in deposition/
26	!.. sublimation/evaporation/melting.
27	!.. Remaining values should probably be left alone.
28	!..
