“Solar UV” Intercomparison 2014

The Program is available here

Within the framework of the EMRP-ENV03 project “Solar UV”, the consortium of the Joint Research Project provides the opportunity to the solar UV community to access the tools and techniques developed during the last 3 years of the project. To decrease current uncertainties in measuring spectral solar UV radiation the achievements of the project will be applied in an Intercomparison of different End-User devices being held on:

7- 16 July 2014 in Davos, Switzerland

The intercomparison will be hosted by the World Radiation Center (PMOD/WRC) and following activities will take place:

-     Intercomparison of global solar irradiance measurements from different instruments (array spectroradiometer, scanning spectroradiometer) with the QASUME reference spectroradiometer.

-     On-site absolute spectral irradiance calibrations using traceable transfer standards.

-     Linearity and wavelength characterisations of array and scanning spectroradiometers using new developed wavelength calibration devices.

The participants of the intercomparison will be introduced to – and can work with - the new developed devices, methods and software such as:

-     UV LED based and Laser Driven Light Source as new portable travel standard

-     Two different wavelength calibration devices

-     A new software tool for stray light correction and bandwidth/wavelength homogenization for scanning- and array spectroradiometer

-     Uncertainty estimation tools for array spectroradiometer

-     The UV hyperspectral imager

A detailed program of the Intercomparison will be available from this web-page by 17 March 2014.

The results of the Intercompasion will be published in a report in August 2014

The services of the Intercomparison and the use of PMOD/WRC UV calibration facilities in the laboratory are free of charge. The participants are requested to register for the entire period of the Intercomparison with this web-page.

The Thematic Network for Ultraviolet Measurement - UVnet - in conjunction with the EMRP UV Intercomparison 2014 will arrange a two-day workshop on

                       July 15 – 16, 2014 in Davos Switzerland

The workshop will be hosted by the Physikalisch-Meteorologisches Observatorium Davos, World Radiation Center (PMOD/WRC)

The workshop will be dedicated to present final results of the EMRP-project ENV03 “Traceability for surface spectral solar ultraviolet radiation. In addition, the participats to the workshop will be introduced to the new devices, methods and software developped within the EMRP-project.

There will be an opportunity to present results of other UV-related activities.
