CIMO Expert Team Meeting on Surface-based Instrument Intercomparisons and Calibration Methods

This was a joint meeting with the International Organizing Committee (IOC) on Surface-based Intercomparisons, held on 24-28 November in Trappes, France.

HMEI was represented by:
§ Gerard Pevny from Logotronic's GmbH
§ Panu Kopsala from Vaisala OYJ

Gerhard Pevny gave an HMEI slide presentation to the meeting.

ET Work Plan and Action Items resulting from this meeting and involving HMEI participation are:

§UNDERTAKE AND EVALUATE INSTRUMENT INTERCOMPARISONS
Laboratory Intercomparisons of rainfall intensity gauges, in two independent certified labs. HMEI will disseminate WMO questionnaire to relevant member companies, for identifying the instruments for comparison (deadline may 2004). Start of Intercomparisons will be September 2004 at University of Genova and one other European site.

Field Intercomparisons of rainfall intensity gauges in various climatic regions; Italy, Slovakia, USA (or elsewhere), plus tropics. HMEI will disseminate WMO questionnaire to relevant member companies, for identifying instruments for Intercomparisons (deadline February 2005). Start of Intercomparisons will be May 2005.

Combined Intercomparisons of thermometer screens/shields, in conjunction with humidity measurements, in various climatic regions, including Arctic/desert areas. HMEI will disseminate WMO questionnaire to relevant member companies, for identifying instruments for Intercomparisons (deadline March 2005). Start of Intercomparisons in Arctic, June 2005. Start of Intercomparisons in tropic regions, February 2006.

§ADDRESS THE DATA HOMOGENEITY ISSUE
In collaboration with CCI, JCOM, CAS and HMEI address the data homogeneity issue.

Review the implication of data homogeneity on climatological, marine and atmospheric science applications and study the role of Intercomparisons in data homogeneity.
