Original Data Quality Flag	Following alphanumeric character are used for flag. 0: valid 1: rejected
Data Quality Flag (Valid/Invalid)	Valid: 0 Invalid: 1
Observation Status	Temporarily suspended
Description	The measurement for air and surface sea water are carried out. The height of intake is about 10m above sea surface and about 5m below sea surface. The water is introduced into the equilibrator. Both introduced ambient air and equilibrated air are dried by the electronic coolong unit, perma pure dryer and chemical dryer (Mg(ClO4)2). Continuous NDIR analizer To reveal the interaction between ambient air and seawater in the western North Pacific Ocean.
