The Improved Stratospheric and Mesospheric Sounder (ISAMS) measured vertical profiles of temperature and a number of atmospheric constituents. An instrument on board UARS (Upper Atmosphere Research Satellite) measured global stratospheric and mesospheric temperature, CO, H2O, CH4, O3, HNO3, N2O5, NO2, N2O and aerosol extinction. Gridded, global measurements between 80S and 80N, October 1991 - July 1992. Data include level 2 and 3A product (gridded in time or latitude along the satellite track). Data are version 9/10 for Level 3 and version 8 for Level 2. ISAMS data is public.

The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains vertical column measurements of NO2 and O3.

Validation data for the IASI (Infrared Atmospheric Sounding Interferometer) satellite instrument. IASI was a moderate resolution (0.25cm^-1) Fourier Transform spectrometer which was scheduled for flight in 2002 on the European METOP satellite. IASI delivered vertical profiles of temperature and humidity data with a resolution of 1km. VIRTEM was an EU project to validate the instrumentation and retrieval methods to be used on IASI.This dataset contains radiosonde, air pressure and air temperature measurements from the C-130 Met Office Hercules aircraft.

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.
