Data Quality Codes:
A - BEST QUALITY DATA -usually with strong, steady wind conditions, and a compact, consistent plume shape.

B - GOOD QUALITY DATA - usually with moderately consistent plume shape and location of plume on road. Collected under moderately strong, uniform winds, with good constraint on wind speed and direction.

C - ACCEPTABLE DATA - may have inconsistent plume location and shape. Wind speed and direction may be variable or poorly constrained. Some runs may measure a partial plume, representing minimum constraints on emission rates. Measurements with instrument inconsistencies are included in this category.


Location Codes:
U- Above the 180° turn at Holei Pali (upper Chain of Craters Road)
L- Below Holei Pali (lower Chain of Craters Road)
UL-traverses above the 180° turn at Holei Pali and below Holei Pali
H- Highway 11

Abreviations: t/d=metric tonne (1000 kg)/day, SD=standard deviation, WS=wind speed, WD=wind direction east of north, N=number of traverses
