The FY-3 satellite is a second-generation Chinese polar-orbit meteorological satellite.The Solar Backscatter Ultraviolet Sounder (SBUS),one of the main payloads on the FY-3 satellite,is the first Chinese ozone-monitoring instrument on a meteorological satellite.As part of the in-orbit validation of FY-3,we carried out a retrieval trial using measurements from SBUS during the period of 17-30 July,2008,and compared those data with measurements and retrieved profiles from the National Oceanic and Atmospheric A... 相似文献

Data from FY-3B SBUS and NOAA SBUV/2 were used to monitor ozone levels in the Arctic region from March 1 to April 5, 2011.
Results revealed a significant ozone depletion in the area, with total ozone levels between 200–250 DU. The ozone levels recorded
were 100–200 DU below normal, and in some parts the levels were as low as 200 DU, indicating a mini ozone-hole. During the
sampling period, the ozone depletion area underwent identifiable expansion and detraction, a rotation around the North Pole
from the west to the east, and a longitudinal movement from the Pole, spreading to the mid latitudes. The effects of these
rare low ozone events were not only felt in the Arctic, but also extended to densely populated areas between Europe and the
middle of Russia. In this region, rapidly increasing levels of ultraviolet radiation were detected at the Earth’s surface.
Given the significant risk that this poses to both the environment and people’s health, this occurrence has significant global
implications. 相似文献
