Inter-comparison experiment :
We implemented the first SF6 inter-comparison experiment (SICE) from May 2016 to Feb 2017 with
8 countries with 12 labs.
There were two circuits which consist of Europe and Asia-Pacific regions.

The Youden plot of differences between participated laboratories and
WCC-SF6.
Red dots indicate WMO-X2014 scale,
green dot WMO-X2006 scale, and black dots Laboratory’s own scale.
X-axis means the differences for low levels cylinders
and y-axis for high level.
CCL and WCC-SF6 are excluded here.
Inter-comparison experiment between WCC-SF6 and CCL :
WCC-SF6 also has implemented biennial comparison activities
with CCL since 2013 to confirm the traceability and compatibility.
In most cases, two labs showed good agreements without
the high level of SF6 in 2015.
Since we analysed the cylinders using one calibration tank without bracketing,
the high level is
behind the compatibility goal due to the non-linear characteristic of micro-ECD.
The Youden plot of the differences between WCC-SF6 and CCL in 2013(magenta), 2015 (green) and 2017 (yellow).
The bar indicates analysis uncertainty of the WCC-SF6. X-axis means the differences
between two labs for low level cylinders and y-axis for high level.
Audits/Technical supports :
We implement the audit with checklist and inter-comparison experiment.
The final report is published after having audits.
Training/Education course :
Asia-Pacific GAW Workshop on Greenhouse Gases (APGG) has been held
by KMA since 2009 to support Asia regions under the GAW umbrella biennially.
As one of the results of the workshop, Asia-Pacific Newsletters on greenhouse gases has been published since 2010.
From 2014, WCC-SF6 training and education course has been every years.
We deliver practical skills which are applicable back their stations.
