The Halogen Occultation Experiment (HALOE) is one of 10 instruments aboard the Upper Research Satellite (UARS), which used solar occultation technique to measure global stratospheric and mesospheric profiles of pressure, temperature, O3, HCl, HF, CH4, H2O, NO, NO2 and aerosol extinction. The dataset contains approximately 30 sunset and sunrise profiles per day between 80S and 80N from October 1991 to 1994. Data are level 2 products i.e. profiles at actual measurement location and not interpolated in horizontal. Data are version 19.
