The one-year leave of absence stretched on, while Namias supervised a seminal sea-level mapping effort, taught future military pilots and civilian forecasters at several training centers, and made extended predictions for several large-scale military offensives. He received a citation from Navy Secretary Frank Knox for his sea-state forecasts for the North African invasion. Namias also made forecasts for favorable periods for the transfer of disabled vessels to other ports for repair; estimates of the likely course of incendiary balloons from Japan; favorable and unfavorable conditions for the possible invasion of Japan; and certain aspects of the meteorology for bombing raids.
