【摘要】：月球微波亮溫數(shù)據(jù)是研究月球表面物理性質(zhì)的重要數(shù)據(jù)源。本文基于嫦娥二號微波輻射計37 GHz通道微波亮溫數(shù)據(jù),計算了亮溫數(shù)據(jù)月球地方時,獲取了月球一天中不同時間段的12幅月表微波亮溫分布圖。其中,月球白天亮溫正異常區(qū)("熱區(qū)")和月球夜晚點狀亮溫負異常區(qū)("冷點")是最為顯著兩類亮溫單元。"熱區(qū)"和"冷點"具有獨特的亮溫特征和晝夜變化規(guī)律:相對周圍環(huán)境,"熱區(qū)"在月球白天亮溫明顯偏高,夜晚亮溫較低,"冷點"在月球夜晚亮溫明顯偏低,白天亮溫略高;與同緯度地區(qū)相比,"熱區(qū)"和"冷點"的升溫和降溫速率都較大。對比分析月表影像圖、Ti O2含量、物理溫度和石塊含量數(shù)據(jù),我們發(fā)現(xiàn):"熱區(qū)"對應月海區(qū)Ti O2含量較高,同緯度地區(qū)的亮溫和Ti O2含量呈明顯正相關(guān),較高Ti O2含量是"熱區(qū)"形成的主要因素;大部分"冷點"中心都對應著年輕輻射紋撞擊坑,"冷點"中心夜晚物理溫度和巖石含量較高,"冷點"地區(qū)亮溫與其夜晚溫度和石塊含量呈負相關(guān)分布,較高的石塊含量是"冷點"形成的主要因素。
[Abstract]:Lunar microwave brightness temperature data is an important data source for studying the physical properties of lunar surface. Based on the microwave bright temperature data of the 37-GHz channel of the Chang 'e-2 microwave radiometer, this paper has calculated the bright temperature data of the lunar local time, and obtained 12 monthly surface microwave bright temperature maps of different periods of the day on the moon. Among them, the positive temperature anomaly area ("hot zone") and the "cold point" region are the two most significant bright temperature units. " The "hot zone" and "cold spot" have unique bright temperature characteristics and diurnal variation law: compared with the surrounding environment, the "hot zone" is obviously higher in the white day of the moon and lower in the night, and the "cold point" is obviously lower in the night of the moon and slightly higher in the white day; Compared with the same latitudes, the heating and cooling rates of "hot zone" and "cold point" are larger. By comparing and analyzing the data of TIO _ 2 content, physical temperature and rock content, we find that the "hot zone" corresponds to a relatively high TIO _ 2 content in the lunar sea area, and there is a significant positive correlation between the bright and moderate TIO _ 2 contents in the latitude region. Higher TIO _ 2 content is the main factor of the formation of "hot zone". Most of the "cold spot" centers correspond to the impact crater of young radiation stripes. The physical temperature and rock content in the "cold point" center are relatively high at night, and the bright temperature in the "cold spot" region is negatively correlated with the night temperature and the rock content. High stone content is the main factor of formation of "cold spot".
