Comments:
_______________
+ In addition to the tables provided in this document the submitter is requested to provide the data files according to the instructions
available on ITU-R SG 3 Web page: Study Group 3 databanks - DBSG3.
(1)
Use ISO 3166-1 alpha-2 country codes.
(2)
This was referring to Rec. ITU-R P.837-1
(In the current version, these zones do not exist).
(3)
For XPD cancellation, the following options apply: 1: none, 2: static, 3: software.
(4)
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)
Tilt angle is referred to polarisation tilt angle with respect to the local horizontal plane.
(6)
Submissions should comply with the acceptance criteria specified in Rec. ITU-R P.311.
In particular Rain rate, XPD and attenuation measurements should be strictly concurrent.
