TL;DR: In this article, an algorithm is presented for retrieving vertical profiles of O3 concentration using measurements of UV and visible light scattered from the limb of the atmosphere, which can be used to measure O3 between 15 km and 50 km with 2-3 km vertical resolution and better than 10% accuracy.

TL;DR: TEMPO was selected in 2012 by NASA as the first Earth Venture Instrument, for launch circa 2018, and it will measure atmospheric pollution for greater North America from space using ultraviolet and visible spectroscopy.

TL;DR: In this article, two instruments were flown on shuttle flight STS-87 to test a new technique for inferring the ozone vertical profile using measurements of scattered sunlight from the Earth's limb.

TL;DR: The International Photolysis Frequency Measurement and Model Intercomparison (IPMMI) as discussed by the authors was held in 1998 to investigate the level of accuracy of photolysis frequency and spectral downwelling actinic flux measurements and explore the ability of radiative transfer models to reproduce the measurements.

TL;DR: In this article, an 80,000 km 2 stratospheric volcanic cloud formed from the 26 February 2000 eruption of Hekla (63.98° N, 19.70° W).
