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
19/5/2011 B. Calpini CIMO
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…)
19/5/2011 B. Calpini CIMO
• (a) Standardization and Intercomparisons;
• (b) Remote-sensing and New Technologies;
• (c) Capacity-building.

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
19/5/2011 B. Calpini CIMO
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.

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
19/5/2011 B. Calpini CIMO
• 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
19/5/2011 B. Calpini CIMO
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
