Variable Type a Description
1 1 CID C*16 Source identifier (16 characters = 4 words)
1 2 TIDATA(1) real Easting UTM or Lambert conformal coordinate
(km) of the source
1 3 TIDATA(2) real Northing UTM or Lambert conformal coordinate
(km) of the source
1 4 TIDATA(3) real Stack height (m)
1 5 TIDATA(4) real Stack diameter (m)
1 6 TIDATA(5) real Stack base elevation (m)
1 7 TIDATA(6) real Building downwash flag (0 = no, 1 = yes)
1 8 TIDATA(7) real Vertical momentum flux factor (0.0 or 1.0) to
simulate structures like rain hats
1 9 TIDATA(8) real User defined flag (e.g., fuel code)
2 b 1-36 BHT real Controlling building heights (m) for each 10° flow
direction, starting 10° from North
3 b 1-36 BWD real Controlling building width (m) for each 10° flow
direction, starting 10° from North
4 c 1-36 BLN real Controlling building length (m) for each 10° flow
direction, starting 10° from North
5 c 1-36 XBADJ real Along-wind distance (m) from the source to the
center of the upwind face of the building for each
10° flow direction, starting 10° from North
6 c 1-36 YBADJ real Cross-wind distance (m) from the source to the
center of the upwind face of the building for each
10° flow direction, starting 10° from North
