Introduction:
WIGOS- DP
Demonstration projects conducted by NMHSs are considered as an
essential component in WIGOS implementation:
• Helps WMO Members to more fully understand WIGOS
concept and keeping them current on its practical development.
• Feedback and lessons learnt from these NMHSs will be
extremely beneficial in understanding others’ expectations of
WIGOS/WIS concept and implementation.

Moroccan WIGOS Demonstration project
•To Improve the quality of climatic and
meteorological observed data in the perspective
of a better integration of the climate in the
National sustainable development,
• To ensure that the national metrological
measurements respond to WMO standards.
WIGOS Priorities:
• To ensure the quality of the observation to meet climate en environmental
requirements, and
• Metadata and Homogeneity for long term stability..
• What is the quality of the measurements of the National Meteorological
Surface Observing Network, and

Specific Goals:
WIGOS Demonstration Project in Morocco consists on standardization and
traceability project that include:
1.
Strengthening material capacities and human knowledge of the
Moroccan Regional Instrumentation Center (RIC) for AR-I and
improving its technical procedures to allow it to accomplish its task
of calibration in link to recognized Metrological International chain ,
2.
Establishment of Metadata catalogues of the whole synoptic,
marine, aeronautic and automatic weather stations constituting the
Moroccan Meteorological Surface observing Network.


IMPLEMENTATION PLAN:
Project 1:
As suggested by CIMO, the four following domains were selected as
areas of enhancement :
a) Setting up of laboratories and purchase of standardization devices;
b) Quality Insurance and control;
c) Training;
d) Assessment of the RIC.

IMPLEMENTATION PLAN:
Project 2:
• Seeing the rapid expansion of cities, more and more synoptic
station had seen their sitting environment modified and in some
cases not fulfilling to standards.
• Information related to calibration, renewing instruments and sensor
exposure are not archived.
By this project, it’s expected to produce documents describing
instrument metadata, as well as, equipment life-cycle:
o Instrument/network sitting,
o Calibration, renewing and maintenance.

Preliminary actions:
• Upgrade of existing laboratory equipments:
repairing existing equipments and connecting
sensors and standards used with the different
equipments to a computer in order to optimize
data collection).
• Construction of a new building to house the
laboratory

Achievement Progress:
For the strengthening of RIC capabilities, three stages were
defined:
1. Acquisition of standards and calibrating equipments to
calibrate instruments measuring atmospheric pressure,
2. Acquisition of standards and calibrating equipments to
calibrate instruments measuring temperature and humidity,
3. Acquisition of calibrating equipments for rain gages.

Training Activities:
• 2008: RIC Staff received training on metrology of pressure and on
installing and handling the new pressure calibrating system,
•December 2009: NMS of Morocco hold the French session of the
WMO course on metrology for the AR-I French speaking countries,
• May 2010: The technical staff of the calibrating laboratory
follows the training in matter of metrology organized by the
African Commission of Metrology (CAFMET).

Quality Insurance:
•NMS of Morocco started, in 2008, a quality circles for support processes like
maintenance and calibration.
• Standards Intercomparison with Meteo-France calibrating Laboratory (RIC for
AR VI) was also achieved in July 2010,
• During the meeting of the CIMO ET on RICs held in Casablanca, the
participants have engaged an assessment test of the RIC of Morocco with
regards to the ISO 17025 requirements and RIC TOR using the new template
evaluating Scheme developed by the ET.
• NMS of Morocco launched the project of certification of the RIC with regards
to the ISO 17025 standard. (the certification project is expected to be achieved by
the end of 2011)

Experiences gained and problems encountered:
The NMS of Morocco and especially its calibrating laboratory considers
that experiences have been acquired in the following areas:
• Making benefit from WIGOS values and taking part, while being satisfied,
to its implementation,
• Definition of needs and establishment of technical specifications of each
materiel to be acquired,
• Management of the acquisition process (budget, acquisition project
achievement…),
• Acquiring knowledge in matter of Metrology and processes related to the
calibration of meteorological instruments,
• Implementing quality control process.

Experiences gained and problems encountered:
• A real difficulty was encountered during the development of calibrating
software. In fact, there was a need of help of technical expert for providing
the way to calculate and determine metrological parameters (uncertainty,
hysteresis, repeatability…).
To overcome this problem, a technical assistance was provided by RIC of
AR -VI.
In
this context, WIGOS should encourage cooperation between
developing and developed countries in matter of interest.
This cooperation should lead to a real knowledge transfer.
25

Experiences gained and problems encountered:
• Difficulties were also encountered when bringing barometers from station
to laboratory (need of replacement).
RIC acquired, to resolve this problem, necessary digital barometers with
LCD screen to replace mercury barometers not fulfilling WMO standards.
(18 digital barometers were acquired in 2009).

WIGOS should emphasize the practical application of its terms of
reference.

The implementation of the concept of WIGOS at different levels
(observation, coding and transmission, modeling, dissemination ...) will
generate some friction that may be exceeded by the definition of clear and
comprehensible procedures and deliverables.

Conclusions:
• NMS of Morocco took into charge the actions mentioned above and the
progress of the project is consistent with the timetable presented to the EC
WG on WIGOS.
• The NMS of Morocco has just completed a large part of the project with
regards to the IP and more efforts are now oriented to develop, to practice
and to assess technical procedures for calibrating processes according to
ISO 17025 standards.
• During the accreditation process, a certified consultant will assist the RIC
staff. However, Experience of developed and certified RICs will be a
precisous aid seeing the fact that, in general, RICs uses to calibrate
similar instruments working in same ranges and responding to the same
WMO tolerances.
