National Oceanic and
Atmospheric Administration, The United States Historical Climatology Network

The U.S. Historical Climatology Network (USHCN) is a moderate-sized data
set of monthly average maximum, minimum, and mean temperature and total
monthly precipitation developed to assist in the detection of regional
climate change. The USHCN is composed of 1221 stations from the U.S. Cooperative
Observing Network within the 48 contiguous states. An additional set containing
46 stations for Alaska is also available. The period of record varies
for each station but generally includes the period 1900-1995. Data are
available as raw (no adjustments), TOB (time-of-observation adjustments),
adjusted (all adjustments except urban heat adjustments), and urban (all
adjustments including urban heat adjustments). Currently, USHCN data are
available on the Web through the National Climatic Data Center (NCDC)
home page.

Earthquakes, Tornadoes, Hurricanes, and Floods
Executive Office of the President, Council on Environmental Quality. Environmental
Trends, 143-147. Washington, D.C., 1989
This publication provides explanations and summaries of natural phenomena.
Although the western states are generally associated with the occurrence
of earthquakes, most of the United States is at some risk. A map of the
United States projects the degree of damage expected if an earthquake
occurs. Tornadoes are most likely to occur in the center of the country,
although a substantial portion of the United States is at some risk. A
map of the United States illustrates historical data of the occurrence
of tornadoes during a 10-year period. Generally, hurricanes form in the
Gulf of Mexico, Caribbean Sea, and Atlantic Ocean between the months of
June and October. The Gulf and Atlantic coasts are at risk of hurricanes
entering their coastal zones. A map of this region illustrates the probability
of hurricane occurrence in any year within a 50-mile segment of coastline.
Approximately six percent of the land area of the contiguous United
States is susceptible to stream flooding. Additionally, low-lying areas
of the Nation's coastline are also susceptible to flooding from coastal
storms and floods. Development of floodplains and changes in land use
affect the magnitude of floods. Flood-control projects may create a
sense of security and may handle most occurrences; however, complete
protection from floods is never achieved. Flooding waters may overtop
or break levees and may exceed upstream reservoir capacity. Flooded
structures that are improperly cleaned after waters subside can encourage
the growth of mold and mildew that affect indoor air quality.
FEMA Map Service
Center Flood Data
Flood data for almost 900 counties across the U.S. is available on the
Federal Emergency Management Agency (FEMA)
Map Service Center (MSC) Web site. These data will be available in a variety

The digital Flood Data are provided through the Internet and on CD-ROM
as part of MSC's distribution and customer support services.

certain criteria. Reporting sectors include the chemical industry, hazardous
waste treatment facilities, the mining industry, petroleum refineries,
and the paper mill industry. An annual national "data release," or summary,
of TRI data are available from the TRI Hotline (800-535-0202). TRI data
are available online through the National Library of Medicine's literature
search site, Internet Grateful Med.

Guide to Odor Thresholds for Hazardous Air Pollutants Listed in the
Clean Air Act Amendments of 1990 (EPA600/R-92/047) March 1992
This report consists of three sections. Section 1 is an introductory
discussion of basic concepts related to olfactory function and the measurement
of odor thresholds. Section 1 also describes the criteria that are used
to evaluate and determine the acceptability of published odor threshold
values. Section 2 contains the tabulated results of a literature search
and critical review of published odor threshold values for the chemicals
listed as hazardous air pollutants in the Clean Air Act Amendments of
1990 at the time of passage. Each odor threshold value is evaluated
according to the criteria discussed in Section 1 and a geometric mean
of the acceptable values is provided as the best estimate of the odor
threshold. Section 3 lists the references used in preparation of this
report.
