Caveats: With respect to time resolution: 24 sec timing changes and is not necessarily constant, depending on the mode that the instrument happens to be in. Not only does the period/interval between each point change, the duration over which the data were taken can change as well. There are several variables in the data files which are not populated in the publicly available data product. These variables include EDENS, TEMP, QP, QM, QT, REDF, and VSW.
