Evaluation of Space Traffic Effects in SBUV Polar Mesospheric Cloud Data

Water-rich rocket exhaust plumes, in particular those emitted by the National Aeronautics and Space Administration Space Shuttle, have been suggested to make a significant contribution to long-term trends in polar mesospheric cloud (PMC) ice water content. We investigate this claim using the combined Solar Backscatter Ultraviolet (SBUV) PMC data record from eight separate instruments, which includes 60 Shuttle launches during PMC seasons between 1985 and 2011. No statistically significant postlaunch signal in PMC total ice is observed based on superposed epoch analysis of the SBUV record. Only a few launches show individual peaks in total ice anomaly above the seasonal background that exceed an empirical threshold, and the maximum cumulative signature from these infrequent cases is typically less than 5\% of the season total in ice mass. Other non-Shuttle launches show circumstantial evidence of possible PMC effects, although supporting evidence for plume transport is not available. We conclude that space traffic effects have been a negligible component of long-term PMC behavior.

Antarctic mesospheric clouds formed from space shuttle exhaust

New satellite observations reveal lower thermospheric transport of a space shuttle exhaust plume into the southern hemisphere two days after a January, 2003 launch. A day later, ground-based lidar observations in Antarctica identify iron ablated from the shuttle\textquoterights main engines. Additional satellite observations of polar mesospheric clouds (PMCs) show a burst that constitutes 10\textendash20\% of the PMC mass between 65\textendash79\textdegreeS during the 2002\textendash2003 season, comparable to previous results for an Arctic shuttle plume. This shows that shuttle exhaust can be an important global source of both PMC formation and variability.
