2. The basic responsibility of Members and their NMSs to
provide universal services in support of safety, security
and economic benefits for the peoples of their coun-
tries
3. The dependence of Members and their NMSs on the
stable, cooperative international exchange of meteo-
rological and related data and products for discharging
their responsibilities
4. The continuing requirement for Governments to provide
for the meteorological infrastructure of their countries,
5. The continuing need for, and benefits from, strengthen-
ing the capabilities of NMSs, in particular in developing
countries, to improve the provision of services
6. The dependence of the research and education
communities on access to meteorological and related
data and products
7. The right of Governments to choose the manner by,
and the extent to, which they make data and products
available domestically or for international exchange.
Recognizing further:
1. The existence of a trend towards the commercializa-
tion of many meteorological and hydrological activities,
2. The requirement by some Members that their NMSs
initiate or increase their commercial activities
3. The risk arising from commercialization to the estab-
lished system of free and unrestricted exchange of data
and products, which forms the basis for the WWW,
and to global cooperation in meteorology
4. Both positive and negative impacts on the capacities,
expertise and development of NMSs, and particularly
those of developing countries, from commercial oper-
ations within their territories by the commercial sector
including the commercial activities of other NMSs.
Reminds Members of their obligations under Article 2 of
the WMO Convention to facilitate worldwide cooperation
in the establishment of observing networks and to promote
the exchange of meteorological and related information;
and of the need to ensure stable ongoing commitment of
resources to meet this obligation in the common interest of
all nations;
Adopts the following policy on the international exchange
of meteorological and related data and products:
As a fundamental principle of the World Meteorological
Organization (WMO), and in consonance with the expand-
ing requirements for its scientific and technical expertise,
WMO commits itself to broadening and enhancing the free
and unrestricted
1
international exchange of meteorological
and related data and products;
Adopts the following practice on the international
exchange of meteorological and related data and products:
1. Members shall provide on a free and unrestricted basis
essential data and products which are necessary for
the provision of services in support of the protection
of life and property and the well-being of all nations,
particularly those basic data and products, as, at a
minimum, described in Annex 1 to this resolution,
required to describe and forecast accurately weather
and climate, and support WMO Programmes
2. Members should also provide the additional data and
products which are required to sustain WMO
Programmes at the global, regional, and national levels
and, further, as agreed, to assist other Members in the
provision of meteorological services in their countries.
While increasing the volume of data and products
available to all Members by providing these additional
data and products, it is understood that WMO
Members may be justified in placing conditions on
their re-export for commercial purposes outside of the
receiving country or group of countries forming a single
economic group, for reasons such as national laws or
costs of production
3. Members should provide to the research and education
communities, for their non-commercial activities, free
and unrestricted access to all data and products
exchanged under the auspices of WMO with the under-
standing that their commercial activities are subject to
the same conditions identified in Adopts (2) above.
Stresses that all meteorological and related data and prod-
ucts required to fulfil Members’ obligations under WMO
programmes will be encompassed by the combination of
essential and additional data and products exchanged by
Members;
Urges Members to:
1. Strengthen their commitment to the free and unre-
stricted exchange of meteorological and related data
and products
2. Increase the volume of data and products exchanged
to meet the needs of WMO Programmes;
3. Assist other Members, to the extent possible, and as
agreed, by providing additional data and products in
support of time-sensitive operations regarding severe
weather warnings
4. Strengthen their commitments to the WMO and ICSU
WDCs in their collection and supply of meteorologi-
cal and related data and products on a free and
unrestricted basis
5. Implement the practice on the international exchange
of meteorological and related data and products, as
described in Adopts (1) to (3) above
6. Make known to all Members, through the WMO
Secretariat, those meteorological and related data and
products which have conditions related to their re-export
for commercial purposes outside of the receiving country
or group of countries forming a single economic group;
7. Make their best efforts to ensure that the conditions
which have been applied by the originator of additional
data and products are made known to initial and
subsequent recipients.
