This report documents a high-level statistical investigation of the frequency and persistence characteristics of historical cloud cover and weather observations recorded in five operating areas of interest (AOIs) located in Canada. In this study, frequency characteristics are used to provide a quantitative measure of the relative occurrences of specific weather events considered limiting to medium altitude long endurance (MALE) unmanned aerial vehicle (UAV) takeoff, recovery and flight operations, as well as those weather events considered to adversely affect electro-optic and infrared (EO/IR) sensor image quality or interpretability. Low cloud ceilings present the most significant constraint to domestic UAV intelligence, surveillance and reconnaissance (ISR) operations during the summer months, while potential icing conditions present the most significant constraint to UAV ISR operations during the rest of the year. Significant benefits in terms of the percent of time possible for UAV flight operations may be achieved by operating UAVs that incorporate anti-icing systems, particularly in the Northwest Passage and Atlantic regions; however, the utility and performance of a UAV ISR platform depends on the combined utility and performance of both the platform and the sensor. This analysis indicates that the sensor would be the critical limiting factor affecting the success of a domestic UAV ISR mission requiring EO/IR imaging at the identification and classification tasking lev
