WMO/IAEA Round Robin Comparison Experiment - Round 7 Results

Round Robin Comparison Experiment 7 (RR7) was conducted from 2020 through 2026 and involved 51 participants. RR7 was delayed by logistical challenges but has now been closed and the data is available for participants.

Value assignments determined by the CCL (or a designated Round Robin reference lab) for all RR7 cylinders are listed in table 1 as time dependent value assignments. Due to the recent CO scale revision, CO reference values are listed for both WMO X2014A and the new WMO X2025 scales.

Data submitted by participants are shown in table 2 along with the CCL value of the cylinders as of the participants analysis date. No quality control of the submitted data has been done by the CCL. Errors in submission should be brought to the attention of the CCL, although we will not be accepting general revisions and instead encourage participants to use the provided reference values in table 1 to do offline comparison for QA purposes.

Note; O₂N₂ & CO₂ isotopes data are not yet available, we anticipate adding these results soon.

The value and scale transfer uncertainty of the standard on date Da (as a decimal year) are:

Drift Correction Formula:

V a l (D_{a}) = c o e f 0 + (c o e f 1 * d t) + (c o e f 2 * d t^{2})

Uncertainty Formula:

U n c (D_{a}) = \sqrt{{(u n c_c 0)}^{2} + {(u n c_c 1 * d t)}^{2} + {(u n c_c 2 * d t^{2})}^{2} + {(s d_r e s i d)}^{2}}

Where dt = Da - tzero.

Time zero (tzero) is set to the weighted mean date to allow the uncertainties of the coefficients to be easily approximated as a function of time without considering the correlations.

Decimal Year Formula:

To convert a specific date and time into a decimal year (e.g., 2023.497), use the ratio of elapsed seconds:

                            Decimal Date = Year + ( Selapsed / Stotal )
                        

S_elapsed = Seconds passed from Jan 1, 00:00:00 to target time.
S_total = Total seconds in that specific year.

Example: July 1 at 12:00 PM in a non-leap year is roughly 15,681,600 seconds into a 31,536,000 second year, resulting in 2023.4972.
