  • These data are held by the BADC for the Natural Environment Research Council (NERC) Molecular Spectroscopy Facility (MSF). MSF provides world-class scientific equipment and support for infrared (IR),visible, and ultraviolet (UV) spectroscopy. The MSF laboratories are used by many UK and international customers in a wide range of research and development programmes. The data are spectra of various atmospheric gases. These data are public. The data held covers the following areas: Water vapour line parameters Molecular oxygen absorption cross-sections Molecular oxygen/nitrogen absorption cross-sections Hydrofluorocarbon (HFC) infrared absorption cross-sections Perfluorocarbon (PFC) infrared absorption cross-sections Computer software

  • The Rutherford Appleton Laboratory (RAL) Cloud Radar was deployed at the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales from April 2005 to June 2006. These data are restricted to registered users for these data only.

  • The Rutherford Appleton Laboratory (RAL) extended Infrared Microwave Sounder (IMS) data set retrieves vertical profiles of temperature, water vapour (H2O), ozone (O3), carbon monoxide (CO), together with cloud optical depth and effective radius and column amounds of minor gases, dust and sulfuric acid aerosol optical depth. The scheme also provides surface temperature and surface spectral emissivity spanning infrared and microwave. Column amounts of the following minor gases are retrieved: Nitric acid (HNO3), ammonia (NH3), sulfur dioxide (SO2), methanol (CH3OH), formic acid (HCOOH) and (for Suomi-NPP only) isoprene (C5H8). The retrieval scheme has been applied to the infra-red and microwave sounders on platforms Metop (IASI, AMSU and MHS) and Suomi-NPP (CrIS and ATMS). The data sub-set provided here comprises four months (April, July, September, December) of Suomi-NPP data in 2018 produced with the horizontal sampling of CrIS, ~18x18 km. Development of the core IMS scheme was funded by the UK’s National Centre for Earth Observation (NCEO) under the Natural Environment Research Council (NERC), with additional funding from EUMETSAT contract EUM/CO/13/4600001252/THH. Development of the extended IMS scheme and production of this Suomi-NPP data sub-set were funded through NCEO. Data were produced by the Remote Sensing Group (RSG) at the Rutherford Appleton Laboratory (RAL).”
