| 英文摘要 | The variations in extinction and microphysical properties in the upper haze of Venus have a significant impact on the chemistry and radiative balance of its atmosphere. In order to study their spatial and temporal distribution, , we analyzed solar occultation data from the Venus Express SPICAV SOIR instruments between 2006 and 2013. To remove the absorption effects of the middle and upper atmosphere of Venus, , we used MODTRAN modeling. Then, , we retrieved the extinction profiles of the upper haze between 67-92 km using the onion-peeling method. Our findings are as follows: : 1) ) The extinction coefficient of the upper haze generally decreases with increasing altitude, , but there are significant variations between different regions. In low latitudes, , the extinction increased sharply early in the mission, , and the average extinction coefficient of the haze showed minimal changes between day and night. The vertical optical depth of the haze layer was approximately 10(-2 ).2) The number density of the upper haze decreases with increasing altitude. From the south to the north pole, , the number density first increases and then decreases. 3) ) The cloud top altitude is higher in low-latitude regions at 82. 7 +/- 5. 8 km, , while in polar regions, , it is lower with the northern polar region at 73. 3 +/- 2. 4 km and the southern polar region at 79. 5 +/- 3. 5 km. The average scale height of the upper haze layer in the northern polar region is 4. 0 +/- 0. 9 km. |
