_______________
+ 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)
Aeronautical ground types: sea water, fresh water, marsh, moist soil, dry soil, sea ice, glacier ice, wet snow, dry snow.
(3)
Duration is the total time of valid measurements for this dataset, expressed as a real number (e.g. 8157.312 hours).
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= 8157.312 hours corresponds to 93.12 % availability).
(4) Submissions should comply with the acceptance criteria specified in Rec. ITU-R P.311.
