Matthew DeLand has updated the SBUV PMC occurrence frequency results through the SH 2006-2007 season. The combined data for all instruments are shown in the figures below. With the launch of AIM, these plots might provide a useful historical perspective. The results are an update to; DeLand, M. T., E. P. Shettle, G. E. Thomas, and J. J. Olivero (2003), Solar backscattered ultraviolet (SBUV) observations of polar mesospheric clouds (PMCs) over two solar cycles, J. Geophys. Res., 108(D8), 8445, doi:10.1029/2002JD002398.
DeLand made this data available as a courtesy to the LPMR-8 website. If you wish to study the data in depth or refer to it professionally, please contact him at matthew_deland@ssaihq.com.
