ENVIRONMENTAL RESEARCH LABORATORIES

The mission of the Environmental Research laboratories is to study the oceans, inland
waters, the lower and upper atmosphere, the space environment, and the earth, in search of the
understanding needed to provide more useful services in improvino man's prospects for survival
as influenced by the physical environment. laboratories contributing to these studies are:

Earth Sciences Laboratories (ESL): Seismolo~y, geomagnetism, geodesy, and related earth
sciences; earthquake processes, internal structure and shape of the earth and distribution of
the earth's mass,

AtLantic Oceanographic and MeteoroLogicaL Laboratories (AOML): Geology and geoohysics
of ocean basins, oceanic processes, and sea-air interactions (Miami, Florida).

pacific Oceanographic Laboratories (POL): Oceanography with emphasis on the oceanic
processes and dynamics; tsunami generation, propagation, modification, detection, and monitoring
(Seattle, Washington).

l--

Atmospheric Physics and Chemistry Laboratory (APCL): Processes of cloud and precipitation
physics; chemical composition and nucleating substances in the lower atmosphere; and laboratory
and field experiments toward developing feasible methods of weather modification.

Air Resources Laboratories (ARL): Diffusion, transport, and dissipation of atmospheric
contaminants; development of methods for p~ediction and control of atmospheric pollution; geo-
physical monitoring for climatic change (Silver Spring, Maryland).

GeophysicaL FLuid Dynamics Laboratory (GFDL): Dynamics and physics of geoohysical fluid
systems; development of a theoretical basis, through mathematical modeling and computer simula-
tion, for the behavior and properties of the atmosphere and the oceans (Princeton, New Jersey).

NationaL Severe Storms Laboratory rNSSL): Tornadoes, squall lines" thunderstorms, and
other severe local convective phenomena directed toward imoroved methods of prediction and
detection (Norman, Oklahoma).

Space Environment Laboratory (SEL): Solar-terrestrial physics, service and technique
development in the areas of environmental monitoring and forecasting.

Aeronomy Laboratory (AL): Theoretical, laboratory, rocket, and satellite studies of
the physical and chemical processes controlling the ionosphere and exosphere of the earth and
other planets, and of the dynamics of their interactions with high altitude meteorology.

WaVe ~opagation Laboratory (WPL): Development of new methods for remote sensing of
the geophysical environment with special emphasis on optical, microwave and acoustic sensing
systems,

Weather Modification ~ogram Office (w.MPO): Plans and directs ERl weather modification
activities. operates ERl aircraft fleet, and research on cumulus cloud modification, on hurricanes
and other tropical problems, and on hurricane modification.
