On the Calibration of a Solar UV Radiometer to Measure Broadband UV Radiation from Blacklight Lamps

Experiments in photocatalysis often involve the use of blacklight UV lamps to simulate the solar UV spectrum under indoor laboratory conditions. solar UV radiometers (such as the Eppley TUVR) which are calibrated for solar UV spectrum require correction when used to measure the energy from a lamp array. This paper describes a transfer calibration procedure that was used to determine instrument response to the blacklight lamp energy spectrum. It also shows theoretically and experimentally that a correction factor of about 1.15 is needed to use a solar UV radiometer for measurements of outputs from the lamps.

High Resolution Observations of Solar Velocity Fields from Spacecraft and Rockets Using Spectroscopic Methods

Progress in the development of rocket and satellite spectrometers has now given us the opportunity to study the solar UV spectrum for evidence of mass motions in the chromospheric-coronal transition region. It is my intent to discuss briefly the motivation behind such space experiments, to summarize the few existent observational results, and to suggest relevant programs to exploit the opportunities offered by space experiments in the future.
