The Middleton Solar SP02 Sunphotometer is a simple low-cost instrument for the determination of the spectral optical depth of the atmosphere. It can be configured for total & aerosol optical depth measurement, column ozone measurement, and assessment of water vapour amounts. It consists of four precision spectro-pyrheliometers axially aligned in a sealed enclosure. The SP02-L version has a narrower field of view to diminish light scatter from the sun aureole in locations that have a high aerosol load, such as northern Europe.
