A detailed specification of requirements is set out in Appendix 1. It is proposed to place a maintenance contract for a period of three years with an option for renewal for up to a further two years. The instrument will be used to measure Ultra Violet, or Visible, radiation in the solar spectrum. By examining the differential absorption of select wavelengths in the UVB portion of the spectrum, determinations of Total Column Ozone and Total Column Sulphur Dioxide can be inferred.
