Abstract
We analyze the monthly average wind velocity at about 12 km above sea level between 1980 to 1995 for San Pedro Mártir, Mauna Kea and other existing observatories and sites of interest. We compare the results obtained from two different data sets, the GGUAS and NCEP. Our results show that San Pedro Mártir and Mauna Kea are comparable and are amongst the most suitable sites to apply slow wavefront corrugation correction techniques.
