Variable Type Description Sample
Values
(Input Group 4 - Air-Mass Map)
NORTH integer array Air-mass type index for each cell along the northern
boundary of the computational grid
WEST-EAST integer array Air-mass type index for the first (west) and last (east)
cell of one row of the computational grid. Records
should progress from north to south, starting with the
second row from the 'top', and ending with the next-tolast
row from the 'bottom'.
SOUTH integer array Air-mass type index for each cell along the southern
boundary of the computational grid
7*1,3, ...
1, 2
4,1,8*2, ...
(Input Group 5a - Air-Mass Definition)
AIRMASS
character
*12
Air-mass name, used to coordinate inputs
regional
IAM integer Air-mass index, used to store properties 2
(Input Group 5b - Explicit Time-Varying Air-Mass Properties)
IBDAT integer Starting date (YYYYJJJ) 2000153
IBHH integer Starting hour (HH), identified by the time at the END
of the hour (00-23 LST)
01
IEDAT integer Ending date (YYYYJJJ) 2000345
IEHH integer Ending hour (HH), identified by the time at the END
of the hour (00-23 LST)
00
Data records follow Input Group 5b (after the !END! terminator)
The first record of each time period defines the range of hours for which the concentration data
are valid by listing the beginning date (YYYYJJJ) and hour(HH), and the ending date and hour.
Subsequent records of each time period provide the data for each air-mass listed in Input Group
5a. Each record contains the air-mass name (in single quotes), the layer-top (m), and the
concentration of each species (units specified by IBCU).
