      GENERATION AND ACTIVITIES OF THE COMMISSION RELATED TO QM

Author: Francesco Sabatini



The WMO Commission for Agricultural Meteorology (CagM),

   1. Cg-XIV Resolution 27 which defines the limits of the WMO Quality Management Framework
        (QMF), which includes
           1. WMO technical standards
           2. Quality Management System(s) including Quality Control
           3. Certification procedures
   2. EC-LVI Resolution 8 which established the Intercommission Task Team on Quality
        Management Framework
   3. The efforts aimed to harmonize the available technical documentation
   4. Relying mainly on the existing technical documentation for weather observations (WMO
        Technical Guide N°8)


Expresses present and future Contribution to QMS as:

           1)   review, integration and updating of WMO specialized documentation
           2)   list of the pertinent documents produced
           3)   interaction with others international Agrometeorological organisations
           4)   QMS-oriented internal organisation of CAgM
           5)   Preliminary comments / recommendations for ICTT-QMF

Contribution should be addressed to the special agricultural weather in identifying the QM
documentation (i.e. soil moisture, leaf wetness, UVB monitoring, etc.


    WMO: 134           Guide to Agricultural Meteorological Practices (GAMP)

            Chapter 2: Agricultural meteorological elements and their observation
            Chapter 3: Agricultural meteorological data, their presentation and statistical
            analysis


   The Guide to Agricultural Meteorological Practices (WMO-No.134) was published in
   1982. The aim of the Guide is to provide, in a convenient form, information regarding the
   most important practices and procedures in agricultural meteorology.

   The guide includes the following chapter topics: Observation, Presentation, and
   Statistical Analysis of Agricultural Meteorological Data; Weather Forecasting for
   Agriculture; Agrometeorological Forecasting; Applications of Meteorology to Agriculture
   and Forestry; Weather Risk Assessment, Aerobiology; Desertification; and Weather and
   Climate and Animal Production.

   The Commission of Agricultural Meteorology (CAgM) is currently updating the GAMP
   and appointed Prof. Kees Stigter as the leader of the Expert Team on the GAMP to
   undertake this revision. Prof. Stigter developed a proposed outline on revising the
   GAMP.

   It could be proposed to Prof. Stigter, to introduce a specific Paragraph or Annex, dedicated
   to basic Quality Management procedures.

       made available free access to technical rules as well as QMS topics for NAgMS’s (National
       Agrometeorological Services)
   •   FAO, Food and Agriculture Organisation. Shared rules for observation generation



PART 4. QMS-oriented internal organisation of CAgM

   1) The CAgM is now based on a Management Group (MG) and three main OPAG’s (Open
      Program Area Group).
         I. OPAGAS, Agrometeorological Services for Agricultural Production
        II. OPAGSS, Support Systems for Agrometeorological Services
       III. OPAGCND, Climate Change/Variability & Natural Disasters in Agriculture

   2) Each OPAG consists of an ICT (Implementation/Coordination Team ) and an Expert
      Team (ET)
   3) OPAG during this period were to assemble the expert teams (now completed), and
      addresses its results to the MG
   4) Interactions in common project. I.e. GAW (Global Atmosphere Watch). Terrestrial UVB
      monitoring network for Biometeorological and Agrometeorological purposes (USDA)

   5) Despite QM is a quite a new task for NMHS’s (and for Agrometeorological Services,
      both at National or local level), some contributions has been done to the first step of
      QA/QC of observational data (i.e. proceedings of Nebraska meeting on AWS, 2000)



PART 5. Preliminary comments / recommendations for ICTT-QMF

   ! It is easy to make things more difficult but it is difficult to make things easy. Be sure
     not to introduce obstacles in normal procedures
   ! Some authors still report problems in reconstructing long term series of air
     temperature observations made in traditional shelter (Stevenson screen) and in new
     double shields. Does a unique QC/QA procedure exists to link past observations?
   ! Unique adoption of widely accepted definitions on quality management elements
   ! web-based distribution of technical rules for meteorological observations as well as
     step by step description of procedures of QA/QC
   ! Examples of QC for specific processes (i.e. AWS Network management) published on
     Internet to help services
   ! Required resources: training of specialists on QM, to directly interact with certification
     firms to reduce final costs
