IOM Report, 134. Report on Interlaboratory Comparison in the field of Temperature, Humidity and Pressure in the WMO Regional Association II, V and VI (MM-ILC-2018-THP-2)
WMO, 2021This report presents the results of an interlaboratory comparison (ILC) with participation of all Regional Instrument Centres (RICs) in WMO Regional Associations (RAs) II and V, using the methodology and experience from the ILC in RA VI in 2016. The ILC was coordinated by RIC Tsukuba (Japan) with support and input from RIC Ljubljana and the University of Ljubljana, Faculty of Electrical Engineering (Slovenia). The results of the ILC in RA II and RA V clearly demonstrate the high capabilities of these RICs, particularly in the domains of temperature and humidity calibration. Some areas requirin ...

This report presents the results of an interlaboratory comparison (ILC) with participation of all Regional Instrument Centres (RICs) in WMO Regional Associations (RAs) II and V, using the methodology and experience from the ILC in RA VI in 2016. The ILC was coordinated by RIC Tsukuba (Japan) with support and input from RIC Ljubljana and the University of Ljubljana, Faculty of Electrical Engineering (Slovenia). The results of the ILC in RA II and RA V clearly demonstrate the high capabilities of these RICs, particularly in the domains of temperature and humidity calibration. Some areas requiring improvement have been identified, mainly in the domain of pressure calibration, thereby the results will assist the laboratories concerned to identify and correct their operations. The results of the ILC have also supported the participating laboratories in maintaining or applying for accreditation according to ISO/IEC 17025. Overall, this is a very positive outcome of the ILC with the goal of improving measurement quality being achieved.

IOM Report, 130. Fourth WMO Regional Pyrheliometer Comparison of RA II, Jointly held with RA V
This report describes the intercomparison in detail: the instruments, the participants, the experimental setup, method and procedure, the data analysis technique used and the results. It is clear from the results that all of the participating instruments have been well maintained and remained stable since the previous intercomparison, which augers well for all radiation measurements within RA II and RA V. All participants were able to return home with newly derived WRR reduction factors for their instruments.

IOM Report, 113. Third WMO Regional Pyrheliometer Comparison of RA II
This report describes this latest RA II intercomparison: the participants (from WRC, Japan, Hong Kong, the Republic of Korea, and Thailand), the intercomparison itself and the results. That all participating instruments except one were found to be well-maintained and highly accurate is a credit to all those who participated, and we can now be confident that solar radiation measurements made in these Asian region countries are reliable and dependable.

IOM Report, 108. WMO International Pyrheliometer Comparison, IPC-XI: final report
The results presented in this report are based on the measurements carried out during the three weeks assigned to the IPC-XI. The favorable weather conditions allowed to acquire a large number of calibration points for most participating instruments. Cloudy and overcast days were used for technical preparations and training of participants as well as for a the IPC-XI symposium and Course on Radiation Measurement. A Saharan Dust Event (SDE) a ected the measurements during several days starting October 8 th . Analyzing the e ect of the SDE on di erent types of instruments led to interesting ndi ...
