Improved Meteorological Packages (IMET)


General Information

Exchanges of heat, gas and water across the air-sea interface couple the ocean and atmosphere in a dynamic system that creates and drives the planet's global climate. To understand this system's role in climate change, scientists have designed an array of buoy-based sensors that measure sea surface temperature, air temperature, wind speed and direction, barometric pressure, solar and long-wave radiation, humidity, precipitation, and levels of aerosols such as ozone. These measurements permit increasingly accurate estimates of air-sea fluxes. The sensor packages include the capability to telemeter some data on a regular basis via satellite to a central data facility
