Ecoregions are based on perceived patterns of a combination of causal and
integrative factors including land use, land surface form, potential natural
vegetation, and soils (Omernik, 1987). This is ...
This dataset supports NRCS resource conservation activities
nationwide. This includes wetlands determinations, soil erosion,
water quality, grazing lands, chemical run-off and many other
CDBS 2.0 contains snow, water, climate, and related hydrologic
information for the U.S., Carribean, and South Pacific. Some
datasets are regional (snow and water). It is a national dataset
Louisiana contains 25 percent of the vegetated wetlands and 40 percent of the
tidal wetlands in the 48 conterminous States. These critical natural systems
are being lost. Louisiana leads the Nation ...
This report contains digital data sets describing water use, toxic chemical
releases, metropolitan areas, and population density of the conterminous United
States. The data source for the water-use ...
The distribution of sedimentary environments presents the limited domain of
deposits from "River Input", the flood tide wedge of "Atlantic Sediment", and
the extensive region of indigenous, recycled ...
Ecoregions denote areas of general similarity in ecosystems and in the
type, quality, and quantity of environmental resources. They are
designed to serve as a spatial framework for the research, assessment, ...
In Crew Earth Observations (CEO), crew members on the International Space Station (ISS) photograph the Earth from their unique point of view in low Earth orbit. Photographs record how the planet is ...
A hand-held Nikon D3s camera was modified to allow near-infrared (NIR) photography from the International Space Station. Astronaut Don Pettit first initiated the camera conversion to collect imagery ...
The "National Surface Water Survey (NSWS)" is a composite
program aimed at monitoring the chemical characteristics of
surface water in the United States. It includes the National
Stream Survey, the ...
The Tropical Cyclone Motion (TCM-90) Research Initiative, sponsored by
the Office of Naval Research (ONR), was a project dedicated to
understanding tropical cyclone motion and improving forecast
The Cooperative Program for Operational Meteorology, Education and Training (COMET) was established in 1989 by NOAA and UCAR as a broad effort to affect meteorology education and training in the United ...

This case contains data from the well-known "storm of the century",
which devastated the eastern third of the United States in mid-March
For more information, see:
This case focuses on the mid-west snow event that occurred mainly on 6
December 1995. The dynamics in this case are subtle, not a classic
super-storm system, and therefore the forecast was challenging. ...
This case focuses on the northern California Flood which occurred 31
December 1996 to 3 January 1997. It was a major hydrologic event with
impressive rainfall with subsequent river flooding and levee ...
This case features wide spread aircraft icing over the midwest to the
northeast United States as well as over the northwest United States.

This case spans the tornadic outbreak on Palm Sunday (27 March 1994)
in Alabama. Gravity waves were triggered with deep convection that
developed in northeastern Texas. The waves modulated mesolows ...
A strong winter storm system moved over Southern California and
brought heavy rain as tropical moisture fed into the system. At the
same time, an intense storm system moved across Florida with tornadoes ...
