Description
Summary:Metadata record for data from ASAC Project 1214 See the link below for public details on this project. Submillimetre Site Testing Data from Dome C, Dec 2000 - Jan 2001 Optical Depth at 350 microns and effective atmospheric temperature at this wavelength, as measured with the SUMMIT (Sub-Millimetre Tipper) experiment on the AASTINO over the austral summer of 2000/2001. Results, and description of the experiment are published in: Calisse, P.G., Ashley, M.C.B., Burton, M.G., Phillips, M.A, Storey, J.W.V., Radford, S.J.E. and Peterson, J.B., 'Submillimeter site testing at Dome C, Antarctica', 2004.
