Abstract:
The data are from a study investigating nitric oxide (NO) variability in the polar mesosphere and lower thermosphere during geomagnetic storms, and the role of energetic electron precipitation in NO production. The datasets include 1) processed atmospheric datasets derived from selected NO observations by the AIM-SOFIE satellite instrument, 2) estimated electron and proton fluxes derived from POES/MEPED/SEM-2 measurements, 3) zonal and meridional wind speeds calculated using the Horizontal Wind Model (HWM14), and 4) geomagnetic indices, solar wind speed, and solar proton event (SPE) data.
Funding was provided by the NERC grants NE/J022187/1 and NE/R016038/1, and the New Zealand Marsden Fund.

| Quality: | The quality of the original data used to generate the datasets are described in cited papers for the Solar Occultation For Ice Experiment (SOFIE), the second generation Space Environment Monitor (SEM-2) Medium Energy Proton and Electron Detector instrument (MEPED), the Horizontal Wind Model (HWM14), and published geomagnetic indices. The data processing to generate the intermediate and final datasets, including data selection, binning, calculation of best estimates and errors, and statistical analyses has been quality checked by the PI / lead data creator (Newnham). | |
| Lineage: | Nitric oxide (NO) partial columns in the high latitude Southern hemisphere upper mesosphere (altitudes 70-90 km) and lower thermosphere (90-110 km) have been derived from observations made by the Solar Occultation For Ice Experiment (SOFIE) onboard the Aeronomy of Ice in the Mesosphere (AIM) satellite. SOFIE NO measurements during 17 geomagnetic storms in the 2008-2014 winters have been binned into selected geomagnetic latitude and geographic latitude / longitude ranges. The fluxes of 30-100 keV and 300 keV precipitating electrons have been estimated from measurements by the second generation Space Environment Monitor (SEM-2) Medium Energy Proton and Electron Detector instrument (MEPED) on the Polar orbiting Operational Environmental Satellites (POES). Zonal and meridional winds at altitudes 80 km and 100 km have been estimated from the Horizontal Wind Model (HWM14). The referenced paper describes the methodology and datasets in detail. |
