As part of the Eastern Pacific Investigation of Climate (EPIC) program, the UOP group has undertaken a study of Long-Term Evolution and Coupling of the Boundary layers in the Stratus Deck regions of the eastern tropical Pacific. The goal of the Stratus project is to observe and understand air-sea interactions and the surface forcing in the region of the cold tongue/intertropical convergence zone (ITCZ).

Beginning in October, 2000, we have maintained a fully-instrumented surface mooring at 20°S, 85°W to collect accurate time series of surface meteorology and upper ocean temperatures, velocities and salinities. The data collected will improve our understanding of the air-sea fluxes and sea-surface temperatures in the Eastern Tropical Pacific.

The Stratus mooring is an OceanSITES Ocean Reference Station, and is World Meteorologcal Organization station number 38400.


The Stratus experiment is supported through the Cooperative Institute for North Atlantic Region (CINAR), a partnership between the Woods Hole Oceanographic Institution (WHOI) and the National Oceanic and Atmospheric Administration (NOAA). Principal funding is provided by the NOAA Climate Observation Division (COD).
