We analyze and interpret physical processes that influence
weather
and climate from hours to decades to provide scientific
information
to support NOAA’s mission.

developed at PSL for research purposes and potential transition
to
operational applications.
Access a wide range of data — from gridded climate datasets
extending hundreds of years to real-time wind profiler data at a
single location — and our online analysis and plotting
tools.
