Why is data from a narrowband UV radiometer more useful than that from a broadband pyranometer?
This question could apply to most areas of the electromagnetic spectrum, but in the UV portion of the spectrum its sharp structure is essentially lost in the integrated nature of a broadband detector. Narrowband UV radiometers such as the SPUV-10, UVMFR-7 and UVRSS-1024 measure either discrete lines or the entire spectrum, respectively. This comes at a price in terms of complexity; hence the market popularity of broadband pyranometers.
