Weather, Water and Climate
Importance of information provided by
Earth-exploration systems including
meteorological systems for a wide
range of economic activities such as
agriculture, transportation,
construction, tourism, etc,
Weather, Water and Climate
Crucial importance of the allocation of
suitable radio-frequency bands for:
 the operation of surface-based meteorological
and related observing systems, including in
particular radiosondes, weather radars, wind
profiler radars
 the operation of Meteorological and R&D
satellites, including remote sensing (passive &
active), data collection and data distribution
links
Importance of radiocommunications for
weather, water and climate operation and
research
XV World Meteorological Congress, 2007
(188 WMO Members)
By Resolution 3:
• Re-affirmed the crucial importance of RF bands for
meteorological and related environmental operations and
research, and for disaster risk reduction
• Stressed that some RF bands are a unique natural resource
for passive sensing that deserve absolute protection
• Urged all Members to do their utmost at national, regional
and international levels to ensure the availability and
protection of suitable RF bands
• Appealed ITU and its Administrations to ensure the
absolute protection of the passive sensing RF bands, and to
give due consideration to the WMO requirements for RF
allocations and regulatory provisions
WMO’s position on the WRC-07 agenda
Issues of prime interest for meteorology:
 Agenda item 1.2:
Extension of the 18 GHz MetSat allocation and
protection of the 10.7 and 36 GHz EESS (passive) bands
 Agenda item 1.3:
Upgrading and protection of radiolocation in the 9 GHz
range, and 200 MHz extension of the Earth exploration-satellite service (EESS)
allocation at 9 500-9 800 MHz
 Agenda item 1.4:
Impact on meteorological radars and satellite C-band
related to future frequency bands for IMT-2000
 Agenda item 1.12:
Coordination and notification procedures for Earth
exploration-satellite service (EESS) (active and passive) sensors
 Agenda item 1.17:
Protection of the 1.4 GHz EESS (passive) band
 Agenda item 1.20:
Unwanted emissions in EESS (passive) bands
 Agenda item 7.2:
WRC-11 agenda
WMO’s position is available as WRC-07 Doc.20 (WMO Information
paper), including WMO Congress Resolution «Radio-frequencies for
meteorological and related environmental activities»
All 188 WMO Members (National Meteorological Services) have been
urged to address the matter with their national radiocommunication
administration
WMO’s position on the WRC-07 agenda
Issues of prime interest for meteorology:
 Agenda item 1.2:
Extension of the 18 GHz MetSat allocation and
protection of the 10.7 and 36 GHz EESS (passive) bands
WMO favours a worldwide allocation in either 18-18.1 GHz band or
18.3-18.4 GHz band. WMO strongly encourages the identification of the
maximum power and eirp for fixed and mobile services that would
protect EESS (passive) in the 10.6-10.68 GHz and the 36-37 GHz
passive bands
 Agenda item 1.3: Upgrading and protection of radiolocation in the 9
GHz range, and 200 MHz extension of the Earth exploration-satellite
service (EESS) allocation at 9 500-9 800 MHz
WMO supports the upgrade to primary of Radiolocation Service in the
band 9 300-9 500 MHz on an equal footing with Radionavigation
Service retaining the provisions that address meteorological radars.
Expecting no potential interference impact to meteorological radar
operations, WMO supports extension to the band 9 300-9 500 MHz of
the EESS (active) and the space research service (active) allocations.
WMO’s position on the WRC-07 agenda
Issues of prime interest for meteorology:
 Agenda item 1.4:
Impact on meteorological radars and satellite Cband related to future frequency bands for IMT-2000
Studies prior to WRC-2000 already concluded on the non-compatibility
between IMT-2000 and radars; WMO is strongly opposed to any
IMT-2000 and IM66-Advanced identification in the 2700-2900 MHz and
5250-5650 MHz bands.
 Agenda item 1.12: Coordination and notification procedures for Earth
exploration-satellite service (EESS) (active and passive) sensors
WMO supports modifications to Radio Regulations to permit recording
and publication of appropriate data pertaining to EESS and SRS active
and passive sensors in the International Master Frequency Register
 Agenda item 1.17: Protection of the 1.4 GHz EESS (passive) band
This band is a vital resource for measuring salinity and other aspects of
the Earth. WMO is of the view that such a secondary FSS allocation
should not be confirmed at WRC-07
WMO’s position on the WRC-07 agenda
Issues of prime interest for meteorology:
 Agenda item 1.20: Unwanted emissions in EESS (passive) bands
WMO supports appropriate regulatory measures in the Radio
Regulations (power limits for unwanted emissions) to ensure the
protection of the Earth exploration satellite service service (passive)
from unwanted emissions.
 Agenda item 7.2:
WRC-11 agenda
WMO supports the retention in WRC-10 agenda of the review of the
uses of the spectrum from 275 to 3 000 GHz by the Earth explorationsatellite (passive), radio astronomy, and space research (passive)
services.
