Section 9: CALPUFF 9.15.6 Relative Humidity File for Visibility Processing in CALPOST (VISB.DAT) The VISB.DAT file is an unformatted data file containing relative humidity data at each surface meteorological station, for each period in the run. It is required if CALPOST will be used to assess visibility. The variable IVIS in Input Group 5 of the control file (see Section 9.1) must be set equal to one in order to create the VISB.DAT file. VISB.DAT File - Header Records The VISB.DAT file consists of at least either NCOM+7 or NCOM+10 header records followed by a set of data records. The header records contain information describing the version of the model used in the run creating the file, horizontal and vertical grid data, a user-input title, a list of the species combinations stored in the output file, and receptor information (see Table 9-58). NCOM, provided in record 2, defines the number of comment records that are present. Comment records are used to transfer the image of CALMET and CALPUFF control files used in the simulation for documentation and QA purposes. Sample FORTRAN read statements for the header records are: READ(iunit) DATASET,DATAVER,DATAMOD READ(iunit) NCOM DO n=1,NCOM READ(iunit) COMMENT ENDDO READ(iunit)CMODEL,VER,LEVEL,IBYR,IBJUL,IBHR,IBSEC,XBTZ, 1 IRLG,IAVG,NSECDT,NXM,NYM,DXKM,DYKM,IONE,XORIGKM,YORIGKM,NSSTA,IBCOMP,IECOMP, 2 JBCOMP,JECOMP,IBSAMP,JBSAMP,IESAMP,JESAMP,MESHDN,NPT1,NPT2,NAR1,NAR2,NLN1,NLN2, 3 NVL1,NVL2,MSOURCE,NREC,NCTREC,LSAMP,NVSOUT,LCOMPR, 4 I2DMET,IUTMZN,FEAST,FNORTH,RNLAT0,RELON0, 5 XLAT1,XLAT2,PMAP,UTMHEM,DATUM,DATEN, 6 CLAT0,CLON0,CLAT1,CLAT2 READ(iunit)TITLE READ(iunit)CVSOUT IF(NDREC.GT.0) READ(iunit)XREC,YREC,ZREC IF(NCTREC.GT.0) READ(iunit)XRCT,YRCT,ZRCT,IHILL IF(NPT1.GT.0) READ(iunit)ISTYPE,CNAMPT1 IF(NPT2.GT.0) READ(iunit)ISTYPE,CNAMPT2 IF(NAR1.GT.0) READ(iunit)ISTYPE,CNAMAR1 IF(NAR2.GT.0) READ(iunit)ISTYPE,CNAMAR2 IF(N LN1.GT.0) READ(iunit)ISTYPE,CNAMLN1 IF(NLN2.GT.0) READ(iunit)ISTYPE,CNAMLN2 IF(NVL1.GT.0) READ(iunit)ISTYPE,CNAMVL1 IF(NVL2.GT.0) READ(iunit)ISTYPE,CNAMVL2 where the following declarations apply: Character*132 COMMENT Character*80 TITLE(3) Character*64 DATAMOD Character*16 DATASET, DATAVER, CLAT0, CLON0, CLAT1, CLAT2 9-297

<strong>The</strong> VISB.DAT file consists <strong>of</strong> <strong>at</strong> least either NCOM+7 or NCOM+10 header records followed by a set<br />

stored in the output file, and receptor inform<strong>at</strong>ion (see <strong>Table</strong> 9-58). NCOM, provided in record 2, defines<br />
