Thermal Structure of the Martian Upper Atmosphere from MAVEN NGIMS

<p>This repository contains&nbsp;data to accompany the publication of our manuscript, &quot;Thermal Structure of the Martian Upper Atmosphere from MAVEN NGIMS&quot;&nbsp;which appears in the Journal of Geophysical Research: Planets.</p> <p>The repository contains .mat&nbsp;files of&nbsp;NGIMS densities and temperatures,&nbsp;as well as associated ephemerides. The filenames have the following structure,</p> <p>&nbsp;</p> <p>mvn_ngi_s3_BIN#_YYYYMMDDtoYYYYMMDD_TID##toTID##_ORBITtoORBIT.mat.</p> <p>&nbsp;</p> <p>Each .mat file contains a MATLAB struct named s3. Each s3&nbsp;struct&nbsp;contains arrays&nbsp;of TIDs, orbits, dates, filenames of&nbsp;data products used to construct the s3, and periapsis information for each orbit. Mean profiles of detector counts and count rates, Ar, CO2, and N2 densities, density&nbsp;corrections, temperatures derived from the densities, altitude, latitude, longitude, local time, solar zenith angle, Ls, heliocentric distance, spacecraft position and velocity, solar latitude and longitude, and NGIMS ram angle&nbsp;are also included. In the &quot;pass&quot;&nbsp;struct&nbsp;within each s3 struct, there are data for each individual orbit in the s3 file. That is, the pass structure contains the data from each orbit which has&nbsp;been binned to obtain the mean profiles in the s3 struct. The pass struct is accessed by commands of the form,</p> <p>&nbsp;</p> <pre><code>s3.pass(n).FIELD</code></pre> <p>&nbsp;</p> <p>where n is an integer between 1 and length(s3.orbit)&nbsp;indicating the orbit in s3.orbit or TID in s3.tid to be accessed and FIELD the field, such as den_Ar (Ar density) or tmp_Ar (Ar temperature), to be accessed.</p> <p>&nbsp;</p> <p>For more information, please contact the corresponding author of the manuscript.</p>
