History ! 11/2005: John Haynes - Created ! 09/2006 placed into subroutine form (Roger Marchand,JMH) ! 08/2007 added equivalent volume spheres, Z and N scalling most distrubtion types (Roger Marchand) ! 01/2008 'Do while' to determine if hydrometeor(s) present in volume ! changed for vectorization purposes (A. Bodas-Salcedo) ! ! 07/2010 V3.0 ... Modified to load or save scale factors to disk as a Look-Up Table (LUT) ! ... All hydrometeor and radar simulator properties now included in hp structure ! ... hp structure should be initialized by call to radar_simulator_init prior ! ... to calling this subroutine. ! Also ... Support of Morrison 2-moment style microphyscis (Np_matrix) added ! ... Changes implement by Roj Marchand following work by Laura Fowler ! ! 10/2011 Modified ngate loop to go in either direction depending on flag ! hp%radar_at_layer_one. This affects the direction in which attenuation is summed. ! ! Also removed called to AVINT for gas and hydrometeor attenuation and replaced with simple ! summation. (Roger Marchand) ! May 2015 - D.

SUBROUTINE cloudsat_precipOccurence ! ! Notes from July 2016: Add precip flag also looped over subcolumns ! Modified by Tristan L'Ecuyer (TSL) to add precipitation flagging ! based on CloudSat's 2C-PRECIP-COLUMN algorithm (Haynes et al, JGR, 2009). ! To mimic the satellite algorithm, this code applies thresholds to non-attenuated ! reflectivities, Ze_non, consistent with those outlined in Haynes et al, JGR (2009). ! ! Procedures/Notes: ! ! (1) If the 2-way attenuation exceeds 40 dB, the pixel will be flagged as 'heavy rain' ! consistent with the multiple-scattering analysis of Battaglia et al, JGR (2008). ! (2) Rain, snow, and mixed precipitation scenes are separated according to the fraction ! of the total precipitation hydrometeor mixing ratio that exists as ice. ! (3) The entire analysis is applied to the range gate from 480-960 m to be consistent with ! CloudSat's 720 m ground-clutter. ! (4) Only a single flag is assigned to each model grid since there is no variation in ! hydrometeor contents across a single model level. Unlike CFADs, whose variation enters ! due to differening attenuation corrections from hydrometeors aloft, the non-attenuated ! reflectivities used in the computation of this flag cannot vary across sub-columns. ! ! radar_prec_flag = 1-Rain possible 2-Rain probable 3-Rain certain ! 4-Snow possible 5-Snow certain ! 6-Mixed possible 7-Mixed certain ! 8-Heavy Rain ! 9- default value ! !
