The 14th International Pyrheliometer Comparison (IPC) in Davos, hosted by PMOD/WRC (22. Sep – 10. Oct 2025) is comming up soon. The registration is open at the PMOD/WRC website.
We are looking forward to meeting you (and your instruments) there. We will offer informal check-ups and software updates to all participating Linard control units, as well as some hands-on refresher courses on radiometer operation.
Davos Instruments is comparing a PMO8 radiometer to the irradiance reference of the Laboratory for Atmospheric Science (LASP) and Space Physics at the University of Colorado in Boulder. LASP’s total solar irradiance radiometer facility (TRF) allows to compare the PMO8 to the NIST traceable reference radiometer NACR5 (White et al. 2022) in a indoor laboratory environment.
Davos Instruments is collaborating with the WSL institute for snow and avalanche research (SLF) to build new instrumentation to determine physical snow properties based on optical methods. Our new instrument, the SnowImager now has its own homepage presenting methods and results from the field. Check it out on www.snowimager.ch
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.
