Characterization of Meteorological and Seeing Conditions at Haleakala

Abstract

Haleakala is the site for numerous telescopes, but the amount of published information on summit conditions is small. We seek to rectify that by presenting several years' worth of data on weather (cloud statistics, relative humidity, temperature, wind speed, and wind direction) and seeing conditions. We also examine the dependence of seeing on wind. Our goal is to provide observers with information that will help them better choose the timing of their observations, and to build up a climatological record for the site. © 2006.
