(1) Use ISO 3166-1 alpha-2 country codes. (2) Indicate the predominant environment at the receive sites. Use codes from Annex 3. (3) This was referring to Rec. ITU-R P.837-1 (In the current version, these zones do not exist). (4) The following categories of measurement are distinguished: 1: Group (cluster of individual spot measurements) 2: Continuous measurement while antenna is moved 3: Sampling (as continuous but sampled at intervals). (5) It is preferred that measurements extend over a distance of 10 to 20 wavelengths. (6) 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). (7) Submissions should comply with the acceptance criteria specified in Rec. ITU-R P.311.
