have complete and timely access to all the information
necessary for the production of weather forecasts and
warnings and other meteorological/climatological
services necessary for the protection of life and prop-
erty and other public interest responsibilities entrusted
to the NMSs and without prejudice to the national laws
of their territory of location
2. NMSs should make their best efforts to ensure that the
conditions which have been applied by the originator
of additional data and products
3
are made known to
initial and subsequent recipients
3. In the case where conditions accompanying the
exchange of additional data and products are not
honoured, the originating NMS may take appropriate
actions including denial of access of these additional
data and products to the receiving Member
4. NMSs may export NWP regional model products
employing additional data and products for commer-
cial purposes outside the country of the Member
running the model, unless objected to by an affected
Member. Every effort should be made to coordinate
the provision of such services prior to implementation
to avoid possible harm to other Members
5. NMSs may distribute and export products from global
NWP models without regard to conditions which
were attached to the original data used in the models
6. Services or products whose construction would suffer
significant degradation by removal of the additional
data or products and from which the additional data
and/or products can be retrieved easily, or their use
can be identified unambiguously, should carry the
same conditions on their re-export for commercial
purposes as those additional data or products
7. An NMS receiving a request from a local client for
service that it cannot fulfil may seek assistance from
another NMS with the capacity to provide it. Where
appropriate to enhance the free and unrestricted
exchange of data and products among WMO
Members, the service should as far as possible be made
available through the offices of the NMS of the country
within which the client is located
8. Similarly, unless other arrangements have been agreed
to, an NMS receiving a request to provide service in
another country should refer the request back to the
NMS in that country, i.e. to the local NMS. In the event
that the local NMS is unable to provide the service for
lack of facilities or other legitimate reasons, the exter-
nal NMS may seek to establish a collaborative
arrangement with the local NMS to provide the service
9. Where the service originated by one NMS is likely to
affect other Members (e.g. in the provision of regional
broadcasts of meteorological information or the wide
distribution of seasonal or climate forecasts), the NMS
originating the service should seek, well in advance,
and take into account the response of the NMSs of the
affected Members, to the extent possible
10. NMSs should, to the extent possible, refrain from
using basic WWW data and products received from
other countries in ways which jeopardize the perfor-
mance of the public interest responsibilities of the
originating NMSs within their own countries. If an
NMS finds that, in the undertaking of its public inter-
est responsibilities it is affected adversely by a public
or private organization in another country, it may warn
the NMS in the country from which the organization
is deriving the data and products. The latter NMS
should consider measures to mitigate these adverse
effects and take those actions appropriate under its
national laws
11. NMSs with experience in commercial activities should
make their expertise available, on request, to other
NMSs, especially NMSs of developing countries,
through the WMO Secretariat and bilaterally, and
provide relevant documentation, seminars and training
programmes to developing countries, on request, on
the same financial basis as other WMO education and
training courses are provided.
In implementing these guidelines, NMSs should take into
account and, as far as possible, respect the different legal,
administrative, and funding frameworks which govern the
practices of NMSs in other countries or group of countries
forming a single economic group. NMSs should, in partic-
ular, note that other NMSs will be bound by their own
national laws and regulations regarding any trade restric-
tive practices. Furthermore, where a group of countries
form a single economic group, the internal laws and regu-
lations appropriate to that group shall, for all internal
group activities, take precedence over any conflicting
guidelines.

UIDELINES FOR RELATIONS BETWEEN
NATIONAL METEOROLOGICAL OR
HYDROMETEOROLOGICAL SERVICES
(NMHS)
AND THE COMMERCIAL SECTOR
Purpose
The purpose of these guidelines is to further improve the
relationship between NMSs and the commercial sector. The
development of the exchange of meteorological and related
information depends greatly upon sound, fair, transparent,
and stable relations between these two sectors.
Guidelines
These guidelines apply to the commercial sector engaged in
meteorological activities, which includes government orga-
nizations engaged in commercial meteorological activities.
