Bertrand CalpiniPresident of CIMO

Cg-XVICg-XVI(Geneva, May 2011)


Promote:– high quality observational data– world-wide compatibility

by:– Defining technical standards, – Testing and calibration– Performing instrument intercomparisons, – Implementing quality control procedures. – Increasing expertise and Capacity-building

for:– Improving quality of products and services

CIMO mission


In WMO High Priorities

• in the Global Framework for Climate Services (GFCS) by improving systematic in situ observations and monitoring of climate

• in WIGOS by improving the availability, usefulness, quality and utilization of observational data and products of all WMO observing systems (in conjunction with other tech commission such as CBS, JCOMM…)


• (a) Standardization and Intercomparisons;

• (b) Remote-sensing and New Technologies;

• (c) Capacity-building.

CIMO working structure


Traceability to SI units

• By publishing guidance on instrumentation for calibration laboratories

• By strengthening RICs centers performances by providing an Evaluation Scheme

• By co-chairing the WMO-BIPM 2010 workshop


Siting of observing stations

• QA observations relies also on proper siting and maintenance of instruments.– CIMO-XV approved a siting classification for

observing stations– Tool for assessing which station to be used for

climate services

• The CIMO siting classification together with ISO TC 146 to become a common WMO-ISO standard.

Differences in the time of occurrence of daily maximum temperatures


Gardaia Results

• Even some low-cost screen appear with very good performance

• Consequences for climate services:– Maximum daily temperature delay: up to 3hrs – Maximum temperature error: up to 1.5deg

• Final report on the WMO CIMO webpage


8th WMO International Radiosonde Comparison.Yangjiang, Guangdong, China

12 July – 3 August 2010

Participants: 11 manufacturers from

China, Finland, France, Germany, Japan, Korea, South Africa, Switzerland, USA

Yangjiang Results

• Unprecedented performances achieved with QRS• No pressure sensor needed anymore for GPS radiosonde

with a direct impact on lowering the cost of radiosonde• Intercomparison results used to facilitate selection of

systems for national purposes, minimizing additional performance testing on a national level (WTO procedures).

• Recommendations on vendors to improve their operational radiosonde

4. Radiation


•87 participants

•40 countries

•99 pyrheliometers


(PAC3 and HF18748 not used in 2010 to define the WRR)

Results

Preliminary results communicated to participants


Financial and HR involved

• From NMHs and vendors:– TOT ca: 4 million CHF– Radiosonde China 2010: ca. 5’500 man-days

• The CIMO mission is achieved by supporting initiatives which by coordinating collective actions by Members with respect to observing systems produce results that exceed what each Member could produce unilaterally to meet their critical needs


Future plans:1. Solid Precipitation


• To improve estimates of solid precipitation / liquid water equivalent snowfall.

• To develop guidance on the accuracy and temporal resolution of solid preciptiation parameters

• In CIMO, SPICE positioned in the context of WIGOS, GFCS, GCW, and in collaboration with other relevant communities (GCOS, EC-PORS, Hydrology…)

Challenges


2. Weather Radar

The Radar Quality Control and Quantitative Precipitation Estimation (QPE) Intercomparison Project


Challenges

• to inter-compare different algorithms for radar quality control with a focus on Quantitative Precipitation Estimation QPE applications

• to develop a method to assess the overall quality of precipitation products from radars globally

(1) Testbeds are centers with experimental facilities to assess the capabilities of various remote-sensing technologies and to provide guidance on remote-sensing instrumentation from a variety of observing systems

(2) Lead centers are centers of excellence for instrument development and testing focused on a specific parameter
