Items in MOBSRC95.DAT:

NFRAQS# - COVER# number for relate to NFRAQS GRID
NFRAQS-ID - NFRAQS grid ID number
CO_W - winter season carbon monoxide
VOC_W - winter season volatile organic compounds
NOX_W - winter season nitrogen oxides
SOX_W - winter season sulfur oxides
NH3_W - ammonia
PM10_W - tailpipe PM10
PM25_W - tailpipe PM25
SAND10_W - PM10 emissions from road from mobile sourcesdue to sanding operations
REENTR10_W - reentrained PM10 emissions from mobile sources

Emission inventory units  are grams / day. 

The scalar to distribute emissions diurnally is as follows:


Mobile Sources Diurnal Distribution:

 hour     %
    1  0.0084
    2  0.0057
    3  0.0050

The PM25 fractions of sanding and reentrained PM10 emission inventories can
be derived using the following fractions:

Reentrained PM25 = .25 * PM10
Sanding PM25 = .25 * PM10

These are the scaling factors used for the Blueprint for Clean Air Emission
inventories.
