README Data for <br> "Martian Gravity Waves Observed by the Thermal Emission Imaging System (THEMIS) during Northern Summer"<br> J. Michael Battalio et al.,<br> November 2022<br> (https://battalio.com)<br> michael[at]battalio[dot]com In this dataset are:<br> GW_readme.txt (this file) numpy compressed files<br> GWDaytime.npz<br> GWNighttime.npz<br> GWSpectrumMY##.npz, where "##" run the eight Mars years from 26 to 33, inclusive.<br> GWSpectrumNightMY##.npz, where "##" run the eight Mars years from 26 to 33, inclusive. Python notebook file:<br> THEMIS_GW_LOAD.ipynb (minimal notebook to read *.npz files) --The following arrays are in GWDaytime.npz:<br> gwArr, gwPeaks, gwArrMax, gwPeaksMax, gwNames, <br> gwArrSym, gwPeaksSym, gwArrSymMax, gwPeaksSymMax, gwNamesSym --The following arrays are in GWNighttime.npz:<br> gwArrNight, gwArrNightSym, gwPeaksNight, gwPeaksNightSym, gwArrNightMax, gwArrNightSymMax, gwPeaksNightMax, gwPeaksNightSymMax, gwNamesNight, gwNamesNightSym The arrays have the following format: Each row in gwArr, gwPeaks, gwArrMax, gwPeaksMax corresponds to a THEMIS swath or sub swath for the name given at the same column index as the gwNames vector. Similarly for gwArrSym, gwPeaksSym, gwArrSymMax, gwPeaksSymMax to gwNamesSym and for the GWNighttime file. gwArr, gwArrMax, gwArrNight, gwArrNightMax, gwArrSym, gwArrSymMax, gwArrNightSym, gwPeaksNightSym array columns are:<br> Swath centroid Longitude, swath centroid Latitude, Spectrum maximum, baseline orientation bin of maximum, baseline length bin of maximum, empty, areocentric longitude, local time, mean of whole spectrum, standard deviation of whole spectrum, Mars year, median of whole spectrum gwPeaks, gwPeaksMax, gwPeaksSym, gwPeaksSymMax, gwPeaksNightMax, gwPeaksNightSymMax, gwPeaksNight, gwPeaksNightSym array dimensions are: Dim1 corresponds to each THEMIS swath given by gwNames, gwNamesSym, gwNamesNight, or gwNamesNightSym. Dim2 corresponds to each of the top-10 peaks in the spectrum (Note: Peak one is identical to the peak given in column 3 of the "Arr" variables.). Dim 3 provides the baseline orientation bin of the corresponding peak, baseline length bin of the corresponding peak, the value of the peak. <br> --The following arrays are in each GGWSpectrumMY##.npz:<br> gwNamesMY##,gwNamesSymMY##,spectrumArrMY##,spectrumArrMaxMY##,spectrumArrSymMY##,spectrumArrSymMaxMY## spectrumArrMY##,spectrumArrMaxMY##,spectrumArrSymMY##,spectrumArrSymMaxMY## array dimensions are: Dim1 corresponds to each THEMIS swath given by gwNamesMY##, gwNamesSymMY##. Dim2 corresponds to the baseline orientation from 90° east to 90° west of a due north-south orientation. Dim 3 provides the baseline length from 0 to 500 km for full swaths or 0 to 60 km for symmetric swaths. --Similarly, the following arrays are each GGWSpectrumNightMY##.npz:<br> gwNamesNightMY##,gwNamesNightSymMY##,spectrumArrNightMY##,spectrumArrNightMaxMY##,spectrumArrNightSymMY##,spectrumArrNightSymMaxMY## The variable dimensions follow the same convention as the daytime files.
