Observations of water vapor with high temporal and spatial resolution and good horizontal coverage just above the tropical tropopause have been scarce, but a preliminary version of such data has been developed using radiance measurements of the Microwave Limb Sounder. These data reveal distinct variations with periods in the ranges 10–25 days and 30–70 days, consistent with (respectively) slow Kelvin waves and the tropical intraseasonal oscillation.
