High Altitude Wind Velocity at San Pedro Mártir and Mauna Kea
نویسندگان
چکیده
We analyze the monthly average wind velocity at about 12 km above sea level, between 1980 to 1995, for San Pedro Mártir, Mauna Kea, another existing observatories and some 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.

Observing Conditions for Submillimeter Astronomy
Consistently superb observing conditions are crucial for achieving the scientific objectives of a telescope. Submillimeter astronomy is possible only at a few exceptionally dry sites, notably Mauna Kea, the Antarctic plateau, and the Chajnantor region in the high Andes east of San Pedro de Atacama in northern Chile. Long term measurements of 225 GHz and 350μm atmospheric transparency demonstrat...
متن کاملSubmillimeter fourier-transform spectrometer measurements of atmospheric opacity above mauna kea.
We present accurately calibrated submillimeter atmospheric transmission spectra obtained with a Fourier-transform spectrometer at the Caltech Submillimeter Observatory on Mauna Kea, Hawaii. These measurements cover the 0.9-0.3-mm wavelength range and are the first in a series aimed at defining the terrestrial long-wave atmospheric transmission curve. The 4.1-km altitude of the Mauna Kea site pr...
متن کاملOptical Turbulence Profiles at Mauna Kea Measured by MASS and SCIDAR
The vertical distribution of turbulence over Mauna Kea has been measured on four nights in 2002 October, simultaneously using two different instruments based on stellar scintillation—the generalized SCIDAR (scintillation detection and ranging) and MASS (multiaperture scintillation sensor). The turbulence integrals match within 20%, and the low-resolution profiles delivered by MASS correctly rev...
متن کاملNumerical Simulation of Airflow over Potential Telescope Sites
Numerical simulation can provide a valuable tool in evaluating the characteristics of possible sites for new telescopes. This technique can provide accurate information about topographically induced atmospheric disturbances and turbulent boundary layers occurring in the high Reynolds number airflows over such sites. Results are given here for simulations of airflow at the two Gemini 8-m telesco...
متن کاملComposition of basaltic lavas sampled by phase-2 of the Hawaii Scientific Drilling Project: Geochemical stratigraphy and magma types
[1] This paper presents major and trace element compositions of lavas from the entire 3098 m stratigraphic section sampled by phase-2 of the Hawaii Scientific Drilling Project. The upper 245 m are lavas from Mauna Loa volcano, and the lower 2853 m are lavas and volcanoclastic rocks from Mauna Kea volcano. These intervals are inferred to represent about 100 ka and 400 ka respectively of the erup...
