In order to enhance the relationship between the two
sectors:
1. In the common interest, the commercial sector is urged
to respect the international data exchange principles
of the WWW and other WMO Programmes
2. The commercial sector is urged to recognize and
acknowledge the essential contribution of NMSs and
of WMO to the activities of the commercial sector.
NMSs and the commercial sector are urged to recog-
nize the interdependence and mutual benefit possible
from cooperative interaction
3. In the case where the NMS of a country, particularly of
a developing country, were to consider itself affected by
the commercial sector’s commercial use of data origi
nated in its own country, all parties involved shall
undertake negotiations to achieve appropriate and
satisfactory agreements
4. Unless authorized to do so by the relevant Member,
commercial sector providers of meteorological
services should not publicly issue warnings and fore-
casts relevant to the safety of life and property in the
country or maritime area where they operate.
Warnings and forecasts relevant to the safety of life
and property publicly issued by the commercial
sector should be consistent with those originated by
NMSs or by other official originators in the course
of the performance of their public service responsi-
bilities
5. In providing services, the commercial sector should be
encouraged to employ meteorological terminology
consistent with established national and international
practice
6. Commercial sector providers of meteorological
services should respect the sovereignty and rules and
regulations of the countries in which they deliver
services;
7. NMSs are encouraged to discuss with their countries’
meteorological community and professional societies
the issues associated with the international activities
of the commercial sector
8. NMSs are encouraged to collaborate with their coun-
tries’ commercial sector and their professional societies
to maximize the use of meteorological information
within their country.
