Description

SOIREE Surface water CO2 Data

Note:
These xCO2, pCO2 and fCO2 have been calculated with

standards calibrated against NOAA standards and are expected
to be final data.

Instruments

LI-COR LI-6262 Gas Analyzer

Supplied Name: Licor 6262 analyser

Supplied Description:

Instrument Type

Generic Name: LI-COR LI-6262 Gas Analyzer

Acronym: LI-COR LI-6262

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/382/

Generic Description:

The LI-6262 CO2/H2O Gas Analyzer measures CO2 flux in the environment. It was manufactured by LI-COR Biosciences Inc. (licor.com) from 1990 through 2005 and serial Numbers for this model have the prefix of IRG3-XXXX. The LI-6262 is a differential, non-dispersive, infrared (NDIR) gas analyzer. The CO2 and H2O measurements are based on the difference in absorption of infrared (IR) radiation passing through two gas sampling cells. The reference cell is used for a gas of known CO2 or H2O concentration, and the
sample cell is used for a gas of unknown concentration. Infrared radiation is transmitted through both cell paths, and the output of the analyzer is proportional to the difference in absorption between the two (LI-6262 CO2/H2O Analyzer Operating and Service Manual, Publication Number 9003-59, March, 1996, pg 18).
