r547b188 rf612b17 19 19 Below-cloud scavenging 20 20 - Gases: 21 21 A and B are the parameters for below-cloud scavenging defined by Eq. scavenging coefficient = A x precipitation-rate^B 22 22 If you migrate from FLEXPART version 9.2 and below this is equal to A and B as it was. 23 23 - Particles: 24 25 26 27 24 A "rain collection efficiency" 25 B "snow collection efficiency" are both defined by Equations 46-47. 26 Suggested values for particle scavenging are A=1.0,B=1.0. 27 Using values A=0.2 and B=0.2 will give results close to the old scavenging scheme of FLEXPART version 9.2 and below. 28 28 29 29 In-cloud scavenging … … 32 32 If you migrate from FLEXPART version 9.2 and below this is equal to Ai and Bi should be set to 1 33 33 - Particles: 34 35 Bi ("Ice Nuclei (IN) efficiency") are both from Eq. 51. 36 37 34 Ai ("Cloud Condensation Nuclei (CCN) efficiency") 35 Bi ("Ice Nuclei (IN) efficiency") are both from Eq. 51. 36 Suggested values for particle scavenging are Ai=0.9 and Bi=0.1. 37 Using values Ai=0.9 and Bi=0.9 should give results cto the old scavenging scheme of FLEXPART version 9.2 and below. 38 38 --------------------------------------------------------------------------------------------------------------------------- 39 39 DRY DEPOSITION 40 40 - Gases: 41 42 43 44 45 41 D is the diffusivity of water vapor and 42 D_i is the diffusivity of the species, 43 H is the effective Henry’s constant, 44 f0 varies between 0 and 1 and gives the reactivity of a species relative to that of ozone. For non-reactive species f0 is 0, for slightly reactive it is 0.1 and for highly reactive it is 1. 45 Dry deposition of gases is switched off by negative D. 46 46 - Particles: 47 48 49 50 51 47 rho specifies the density of the substance, 48 dquer its mean diameter 49 dsig the measure of variation. 50 If no detailed information for deposition velocity calculation is available, a constant deposition velocity vd [cm s-1] can be used. 51 Dry deposition of particles is switched off by negative rho. 52 52 --------------------------------------------------------------------------------------------------------------------------- 53 53 OH REACTION: 54 55 54 can be turned on by giving parameter C [cm^3/molecule/sec]], D [K] and N [no unit] positive values, defined by Eq. 39. 55 OH reaction is switched off by negative C. 56 56 --------------------------------------------------------------------------------------------------------------------------- 57 57 Optionally emission variation information 58 58 can be added at the end of the file, defined as following: Since FLEXPART version 6.0, emission factors can be defined that change the temporal variation of particle releases. This is useful, for instance, 59 59 to simulate the typical daily and weekly cycle of anthropogenic emissions. The emission factors are given in the file of the 60 60 corresponding species SPECIES_nnn, where nnn is the species number defined in file RELEASES. If no emission variation
