Fabry-Perot Interferometer (FPI) Data at Mt. John



This dataset contains Fabry-Perot interferometer data from Mt. John for the Study of Deeply Propagating Gravity Waves from the Earth's Surface to the Mesosphere (DEEPWAVE) project. The data is in columnar ASCII format. The reported measurements are horizontal and vertical winds and kinetic temperatures.  The time between successive measurements is light-limited and has been arbitrarily set such that OI 557.7 nm emission measurement uncertainties (for example) do not exceed about 10 K and 5 m/s  respectively for temperature and winds.  Emission rates are reported as counts normalized for unit time.  They are not calibrated, and are given as base-10 logarithm (relative emission rate) * 1000. See the readme for further information.
