Abstract

This dataset is supporting the article "Future Decreases in Thermospheric Neutral Density in Low Earth Orbit due to Carbon Dioxide Emissions". Published in JGR Atmospheres, Volume126, Issue8, 27 April 2021, e2021JD034589 https://doi.org/10.1029/2021JD034589 The data portrays Neutral density scaling tables for empirical atmospheric models to account for thermospheric contraction due to carbon dioxide emissions. Scaling factors that can be applied to the neutral densities obtained from empirical atmospheric models, particularly NRLMSISE-00. These are designed to account for the reductions in density within the upper atmosphere caused by carbon dioxide emissions. They were created using WACCM-X (see https://doi.org/10.1029/2021JD034589 for further details on the low solar activity data). Each scaling factor is relative to the year 2000, and is dependent upon altitude (range 100-500 km), solar activity through F10.7 (70-200 sfu) and ground-level carbon dioxide concentration (368.9 to 890.0 ppm, covering years 2000-2100 in the RCP8.5 scenario). RCP refers to the Representative Concentration Pathways of the IPCC's Fifth Assessment Report. ScalingArray.txt is dependent upon carbon dioxide concentration, while each .txt file with an RCP appended is dependent upon the year (2000-2100) instead, following the carbon dioxide concentrations of the named RCP. Each file contains information on the format of the table used.
