Site selection for an astronomical observatory on Madeira

摘要

Abstract: Possible sites for an astronomical observatory have been explored. Maritime stable air is expected to reach Pico de Paul (1640 m) almost perfectly unaltered, 4 km windward from the sea, providing there is extremely good seeing. About 62% of the nights in summer and 41% of the nights in winter are expected to be clear. Seeing measurements have been started. !5
