Difference of CALIOP Transient Response Between Winter and Summer in Northern Hemisphere
The transient responses of the CALIOP instrument in the 532 nm parallel and perpendicular channel are derived and analyzed from the CALIOP level 1 version 3 products in the winter and summer of 2008. The results show that there is great difference between winter and summer in northern hemisphere. For the reason that Antarctic and Greenland are almost entirely covered by snow and ice all the year round, the characteristic of transient response on these land cloud be a basis for judging whether the transient response is caused by snow or ice in somewhere else. The distribution statistics of about 41.8% samples in winter are the same as that of the samples in summer in northern hemisphere. It means these areas are not covered by snow and ice. The other 52.8% samples’ statistics are consistent with the samples on Antarctic and Greenland, indicating that these areas are covered by snow and ice.
