MLO Seeing Study Report


Sonic anemometers were deployed during Summer 2006 at the Mauna Loa Observatory, Hawaii to quantify the atmospheric seeing quality, to help NCAR/HAO plan current and future telescope observations. This study was intended to replicate measurements made previously for planning the Advanced Technology Solar Telescope (ATST). Deployment and operations for this study were done by HAO staff, and ISFF provided equipment and some data management support.

Site Description

The instruments were deployed on an existing 40m tower operated by NOAA at the Mauna Loa Observatory. The sonic heights were 6.045, 13.3, and 23.2m. They were mounted on the east side of the tower because in June and July the prevailing wind is from the NE. Two additional NOAA anemometers were located at 10.2 and 38.2m. Temperature was measured at 2.0, 9.0, 37.4m.
