Trans-Pacific Profiler Network

The Trans-Pacific Profiler Network (usually abbreviated as TPPN) is a system in which wind profilers are installed on six remote island sites to collect information from data sparse areas in the tropical Pacific Ocean. It is operated by the Aeronomy Laboratory of the National Oceanic and Atmospheric Administration (NOAA) together with the Joint Institute at the University of Colorado.

Various types of Information about the atmosphere, such as precipitation and wind motions, are recorded. These data help in weather forecasting as well as predicting meteorological phenomena like El Niño.
