Description of Files in Data Archive These files provide the processed data shown in Figures 2 through 11 in the paper "Correlations Between the Thermosphere's Semi-Annual Density Variations and Infrared Emissions Measured with the SABER Instrument" by Weimer et. al. The sources of the original input data, including that shown in Figure 1, are available online at the URLs documented in the acknowledgements in the paper. These files are all formatted as "NetCDF," and readable with any NetCDF software library. "TLE" refers to the global mean densities derived by John Emmert using two-line orbital elements, at ten different altitudes The content of these files are: ---------------------------------------------------------------------------------------------------- File: Figure2Data.nc Contains variables: Log10MSIS: FLOAT(10,17167) = Base 10 Logarithm of the global average MSIS density at 10 different altitudes Altitudes: FLOAT(10) = Altitude in km Sigma: FLOAT(10,17167) = Uncertainty of the density ratios MSISrhoRatio: FLOAT(10,17167) = Ratio of TLE measured and MSIS model densities (original, uncorrected values) JulianTime: LONG(17167) = Julian Dates ---------------------------------------------------------------------------------------------------- File: Figure3Data.nc Contains variables: TLE_MSISRatios: FLOAT(2975) = Ratio of TLE measured and MSIS model densities, interpolated to time and altitude of CHAMP measurements, with TLE correction MeasuredRatios: FLOAT(2975) = Ratio of measured (CHAMP) and MSIS model densities Satellite_Altitude: DOUBLE(2975) = Altitude of CHAMP satellite in km JulianTime: DOUBLE(2975) = Julian Dates ---------------------------------------------------------------------------------------------------- File: Figure4Data.nc Contains variables: TLE_MSISRatios: FLOAT(3075) = Ratio of TLE measured and MSIS model densities interpolated to time and altitude of GRACE A measurements, with TLE correction MeasuredRatios: FLOAT(3075) = Ratio of measured (GRACE A) and MSIS model densities Satellite_Altitude: DOUBLE(3075) = Altitude of GRACE A satellite in km JulianTime: DOUBLE(3075) = Julian Dates ---------------------------------------------------------------------------------------------------- File: Figure5Data.nc Contains variables: TLE_MSISRatios: FLOAT(1449) = Ratio of TLE measured and MSIS model densities, interpolated to time and altitude of GOCE measurements, with TLE correction MeasuredRatios: FLOAT(1449) = Ratio of measured (GOCE) and MSIS model densities Satellite_Altitude: DOUBLE(1449) = Altitude of GOCE satellite in km JulianTime: DOUBLE(1449) = Julian Dates ---------------------------------------------------------------------------------------------------- File: Figure6Data.nc Contains variables: PriorSABERFitRatio: FLOAT(4319) = Result from fitting SABER measurements to the ratio of TLE measured and MSIS model densities, interpolated to initial Swarm A altitude, prior to start of Swarm A data, with TLE correction TimePriorSABERFit: DOUBLE(4319) = Julian Dates of SABER data, prior to start of SwarmA data TLE_MSISRatios: FLOAT(4351) = Ratio of TLE measured and MSIS model densities, interpolated to initial Swarm A altitude, with TLE correction TimeMSISRatios: DOUBLE(4351) = Julian Dates of the TLE data MeasuredRatios: FLOAT(1493) = Ratio of measured (Swarm A) and MSIS model densities Satellite_Altitude: DOUBLE(1493) = Altitude of Swarm A satellite in km SABERFitRatio: FLOAT(1493) = Result from fitting SABER measurements to the ratio of TLE measured and MSIS model densities, interpolated to time and altitude of Swarm A measurements JulianTime: DOUBLE(1493) = Julian Dates, Swarm A ---------------------------------------------------------------------------------------------------- File: Figure7Data.nc Contains variables: Frequency: FLOAT(5841) = Frequency, in Days^-1 Response: FLOAT(5841) = Band-Pass filter amplitude response ---------------------------------------------------------------------------------------------------- File: Figure8Data.nc To draw this figure, three data arrays were created by joining together data from three different satellites (for each array).
