VISB.DAT File - Data Records
The VISB.DAT data records consist of a set of "NVSOUT+1" records for each hour of the CALPUFF
runs (where NVSOUT is always one). The first record of each set contains the date and hour of the data
in the records which follow it. The next "NVSOUT" records contain the relative humidity reported in %
at each meteorological surface station if I2DRH=0, or at each sampling grid cell if I2DRH=1 (see Table
9-59).
Sample FORTRAN read statements for the data records are:
READ(iunit)nyrb,njulb,nhrb,nsecb,nyre,njule,nhre,nsece
READ(iunit) istype,isnum,sname,sxkm,sykm
IF(I2DRH.EQ.0) THEN
READ(iunit)CNAME,IRHSS
ELSE
READ(iunit)CNAME,IRH2D
ENDIF
where the following declarations apply:
Character*15 CNAME
Integer IRHSS(NSSTA)
Integer IRH2D(nxm,nym)
