Use ISO 3166-1 alpha-2 country codes..
(2)
Wherever possible values of mV and V for both individual years (= 12 consecutive months) and multi-year observation periods.
(3)
If outages occurred in the measurement of water vapour columnar content, provide in comments information on when the outage
occurred.

Duration is the total time of valid measurements for this dataset, expressed as a real number (e.g. 339.888 days).
The ratio of duration to the period identified by the start and the end dates of this dataset is the availability (e.g. start=2001/1/1,
end=2001/12/31, duration= 339.888 days corresponds to 93.12 % availability).
(5)
Submissions should comply with the acceptance criteria specified in Rec. ITU-R P.311.
