Abstract
Chang'E-2 passive microwave radiometer (MRM) data from two frequency channels (3 and 37 GHz) were converted into brightness temperature (Tb) maps to study large lunar mare provinces in Oceanus Procellarum and the Imbrium basin. Twenty-four locations were identified with the largest differences between midday and midnight Tb values. These areas were then analyzed and compared against 16 geochemical data sets. A numerical relationship was derived between iron, titanium and rock abundance using three sample points from large, young craters. Additionally, a 1,760 km cross-section of the region of interest was investigated to assess potential common trends among the data sets and microwave radiance, finding the strongest correlation with elemental abundance estimations derived from gamma-ray data. Longer-wavelength data have the potential to probe deeper into the regolith layer and assess composition while minimizing the effects of surface contamination by allochthonous materials.
期刊介绍：
The Journal of Geophysical Research Planets is dedicated to the publication of new and original research in the broad field of planetary science. Manuscripts concerning planetary geology, geophysics, geochemistry, atmospheres, and dynamics are appropriate for the journal when they increase knowledge about the processes that affect Solar System objects. Manuscripts concerning other planetary systems, exoplanets or Earth are welcome when presented in a comparative planetology perspective. Studies in the field of astrobiology will be considered when they have immediate consequences for the interpretation of planetary data. JGR: Planets does not publish manuscripts that deal with future missions and instrumentation, nor those that are primarily of an engineering interest. Instrument, calibration or data processing papers may be appropriate for the journal, but only when accompanied by scientific analysis and interpretation that increases understanding of the studied object. A manuscript that describes a new method or technique would be acceptable for JGR: Planets if it contained new and relevant scientific results obtained using the method. Review articles are generally not appropriate for JGR: Planets, but they may be considered if they form an integral part of a special issue.
