Gemini/TEXES Spectroscopic Observations of Jupiter (March 12-14 2017)

This dataset contains Gemini/TEXES spectroscopic maps of Jupiter, acquired between March 12-14 2017 in support of NASA's Juno mission. The data and its reduction/analysis is fully described in Fletcher et al. (2020), Jupiter's Equatorial Plumes and Hot Spots: Spectral Mapping from Gemini/TEXES and Juno/MWR, Journal of Geophysical Research - Planets. As described in that paper, TEXES scan maps were acquired in seven groups (three on March 12, three on March 13, and one on March 14), with each group containing scan maps at 9 spectral settings (539, 587, 745, 819, 900, 960, 1165, 1248 and 2145 cm-1). Each setting spans approximately 10-20 cm-1, with variable spectral resolution as described in the article. Each scan map has been geometrically registered (i.e., latitudes, longitudes, and emission angles have been assigned), wavelength calibrated, and destriped. Radiometric calibration is in its raw form, based on TEXES observations of the telluric sky emission and a blank card in the instrument. However, we found it necessary to scale these spectra to match observations from Cassini/CIRS, using the following scale factors for all spectra: fac538= 0.9 fac587= 0.687705 fac744= 0.872656 fac819= 0.600016 fac901= 0.544984 fac960= 0.427803 fac1161=0.636066 fac1248=1.0 fac2145=1.0 The format of the individual files (IDL "save" files) is as follows: EMMIMG FLOAT = Array[721, 361] - emission angles for each point in the map HDR STRING = Array[126] - header containing information about each observation IMAGE_REDUCT FLOAT = Array[149, 183] - summed image of Jupiter from all points in a spectral scan. IMG FLOAT = Array[374, 721, 361] - cylindrically mapped Jupiter data at 374 wavenumber positions. OLAT FLOAT = Array[361] - planetographic latitudes OLON FLOAT = Array[721] - System III West longitudes. SKY FLOAT = Array[374] - sky emission on the wavenumber grid. SUBLAT FLOAT - sub-observer latitude SUBLON FLOAT - sub-observer longitude TRUESKY FLOAT = Array[374] - sky emission on the wavenumber grid. WAVENUMBER DOUBLE = Array[374] - wavenumber array
