Spectral radiometer data collected at Halley Station, 2005
GB/NERC/BAS/PDC/00717

Summary

Abstract:
Actinic fluxes were measured using the BAS spectroradiometer, between 7 January 2005 and 10 February 2005. Measurements taken mostly relate to down-welling flux, but the spectroradiometer was periodically inverted to record up-welling flux.

This work was carried out at the Clean Air Sector Laboratory (CASLab) at Halley Station, Antarctica, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

The dataset provides ratios given as j-values for jO1D, nitrogen dioxide (jNO2) and nitrous acid (jHONO), at approximate one-minute intervals.
