4 a. Standardization - ET on Upgrading the
Global Radiosonde Network

• Conclusions and recommendations on reference
  radiosondes
• To date, the development of RR has not been
  successfully achieved.
• Designation of Higher Quality Radiosonde (HQR)
  be adopted for the best operational and research
  radiosondes, a combination of which will be used
  for referencing.
• ET developed the requirements for HQR that should
  ensure data comparability among variety of U/A
  systems and permit accurate calibration of remote
  sensing systems.
• Next (2005) WMO Radiosonde intercomparison should
  evaluate the performance of new generation high
  quality radiosondes.
• GCOS reference stations should use HQR coupled
  with additional sensor packages (three thermistor
  references, hygrometer).

4 a. Standardization - ET on Upgrading the
Global Radiosonde Network

• Recommendations on Flexible U/A Systems
• Can use different navigation and tracking
  systems
• Can use various radiosonde types (for user
  choice)
• Can use both GPS and (cheaper) non-GPS
  radiosondes
• Impacts
• Flexible Systems should minimize the impact on
  the on the cost of the continuous improvements of
  the U/A systems
• Should have a positive impact on the operational
  cost of U/A systems
• There is a need to
• Develop further the concept
• To assist in development and testing (for the
  integrity of global data)
• Candidate system will be tested in Tanzania
  (2004-2005) and will participate in WMO
  Radiosonde Intercomparison (2005)

4 a. Standardization ET/IOC on Surface-Based
Instrument Intercomparisons

• WMO Laboratory Intercomparison of RI gauges
• Main objective
• To test the performances of catchment type
  rainfall intensity gauges of different measuring
  principles under documented conditions.
• Further objectives
• To define a standardized procedure for laboratory
  calibration of catchment type rain gauges,
  including uncertainty of laboratory testing
  devices within the range from 2 to 2000 mm/h.
• To identify and recommend the most suitable
  method and equipment for reference purposes for
  the field intercomparison of catching and
  non-catching types of gauges.
• To provide information on different measurement
  systems relevant to improving the homogeneity of
  rainfall time series with special
  consideration given to high rainfall intensities.

4 a. Standardization ET/IOC on Surface-Based
Instrument Intercomparisons

• WMO Field Intercomparison of RI gauges
• Main objective
• To intercompare the performances of in situ RI
  instruments of different measuring principles in
  high RI conditions.
• Further objectives
• To test the accuracy and availability as well as
  the general performanceof the RI instruments in
  field conditions.
• To advice on the need for laboratory tests of
  non-catching type instruments.
• To provide guidance on improving the homogeneity
  of long-term records of rainfall with special
  consideration given to high rainfall intensities.

4 a. Standardization ET/IOC on Upper-Air
Systems Intercomparisons

• Preparations of WMO Intercomparisons of High
  Quality Radiosonde Systems, Vacoas, Mauritius,
  7-27 February 2005
• Special Project Team established, comprising the
  ET/IOC Chairman, Project manager, Radiosonde
  Comparison Expert and Data Manager, supported by
  the local support staff.
• Recognized WRSKOMP software to be used for data
  acquisition, processing, analysis and archiving
  of intercomparison data.
• New strategy for publication of results to
  address the concern with the length of time to
  achieve publication of results.
• Detailed operational procedures agreed.
• Offered support from HMEI and participating
  manufactures.

4 a. Standardization ET/IOC on Upper-Air
Systems Intercomparisons

• WMO Intercomparisons of High Quality
  radiosonde Systems Vacoas, Mauritius, 7-27
  February 2005
• Main objectives
• To improve the accuracy of daytime radiosonde
  measurements and the associated correction
  procedures to provide temperature and relative
  humidity accuracies currently possible with
  night-time measurements.
• To test the accuracy and availability as well as
  the general performance of data obtained from the
  GPS wind measuring systems.
• To evaluate the performance and usefulness of
  geometric and geopotential height values obtained
  from GPS radiosondes.
• To evaluate the differences of temperature,
  relative humidity and pressure sensors of widely
  used radiosondes against newly developed high
  performance sensors and to identify, as far as
  possible, the origins of differences.
• To recommend the best combination of radiosondes
  to be used for referencing for GCOS and for
  satellite data calibration.
