Overview
QASUME is a travel reference UV spectroradiometer which allows inter-comparison campaigns of global solar irradiance measurements from different instruments (array spectroradiometer, scanning spectroradiometer) to be conducted at the user’s site rather than at PMOD/WRC.
QASUME Site Audit
Stationary spectroradiometer systems can be calibrated by a visit of the QASUME spectroradiometer. The visit usually lasts five days with two days needed for travel and setup time and three days for inter-comparison between the host and the reference instrument. After a QASUME site audit, a detailed report of the inter-comparison and a calibration certificate are issued. It is recommended that a visit is repeated to ensure the long-term stability of the system.
