The dataset contains 590 (transformed) daily maxima of five
air pollutants recorded in Leeds (U.K.) during five winter seasons (November-Februrary)
between 1994 and 1998. Contains
NA's. Marginal transformation to unit Frechet was perfomed
by Cooley et al. (2010). Outliers have been removed according to Heffernan and Tawn (2004).
A 590*5 matrix.
The transformation to unit Frechet margins of the raw data has been considered by Cooley et al (2010). Only the 100 data points with the largest radial components were kept.
