The NREL Pyrheliometer comparison in Golden USA is in full gear. The event has started with almost ideal sky conditions, good data has been collected right from the start. Davos Instruments staff is enjoying the event, having many opportunities for fruitful discussions among experts.
This last week of June, an impressive installation of different radiometers has been set up in Lignan (Aosta, Italy). It is the 11th International Spectroradiometer and Broadband Intercomparison 2023 (ISRC) organised by the Joint Research Centre (JRC). More than a dozen institutions from the fields of solar energy research and meteorology are taking part in this event. Comparing and calibration their equipment. Davos Instruments is operating its PMO8 reference as well as two radiometers on behalf of the World Radiation Centre.
Another exciting pyrheliometer comparison is taking place: The Baltic Region Pyrheliometer Comparison (BRPC), hosted by SMHI, the Swedish Meteorological and Hydrological Institute. Davos Instruments is very pleased to participate in this event.
Davos Instruments is currently participating in the fifth WMO Regional Pyrheliometer Comparison of WMO RA-II, jointly held with RA-V on Mount Tsukuba in Japan, an exciting event having approximately 20 absolute radiometers and many experts here. It is a great pleasure to be here and enjoy valuable discussions, excellent infrastructure and delicious meals.
Proceedings from the WMO Technical Conference on Meteorological and Environmental Instruments and Methods of Observation
(TECO-2022) are now publicly available here. Markus Suter (Davos Instruments) and Wolfgang Finsterle (PMOD/WRC) have contributed their work: Adaptive diffraction corrections in solar radiometry, a prerequisite for the ISO 9060:2018 AA class.
