Microwave Observation of the Moon by Chang’E 1 and 2

The microwave radiometers carried by Chang’E 1 and 2 made the first ever microwave study of the Moon in space (@200 and 100 km above lunar surface, respectively).  The data, however, was very messy when laid down on a map, and the Chang’E 1 and 2 data sets did not agree!  We will discuss what messed up the data and how the trouble could be fixed.  The corrected data showed compatibility between the microwave and optical maps and resulted in the discovery of cold microwave spots dotting the Moon in night time.  We will also discuss what could be the cause of these spots.
