A new dynamically generated Local Climatological Data (LCD) product will be available through the
Climate Data Online Data Tools page in 2015.
This new product combines the old ULCD,
and Edited LCD publications into one.
Once the new LCD product is online, the ULCD and QCLCD systems will be taken offline,
and the Monthly Edited LCD will no longer be published.
Historical issues of the Edited LCD Publication, as well as future Annual Editions,
will continue to be available through the Image and Publications System.
A sample of the new form and
ASCII output is provided for your review.
If you have questions or concerns, please contact NCDC Customer Support at 828-271-4800 or
Local Climatological Data (LCD) contains summaries from major
airport weather stations that include a daily account of temperature
extremes, degree days, precipitation amounts and winds. Also
included are the hourly precipitation amounts and abbreviated
3-hourly weather observations. This is the final quality controlled copy and generally has a one to
two month time lag.
Climatological Data (CD) monthly publication/annual contains
station daily maximum and minimum temperatures and precipitation
amounts. Some stations provide daily snowfall, snow depth,
evaporation, and soil temperature data. Each issue also contains
monthly summaries for heating and cooling degree days (65 degrees F
base). The July issue also contains monthly heating degree days and
snow data for the preceding July through June. The annual issue
contains monthly and annual averages of temperature, precipitation
amounts, temperature extremes, freeze data, soil temperatures,
evaporation, and a recap of monthly cooling degree days. This is the
final quality controlled copy and generally has a four to six month
time lag. Over 8000 stations are active nationwide.
The final issue of the Hourly Precipitation Data
publication was the December, 2012 issue.
Historical issues of this publication will continue to be available
through the Images & Publications System.
A new, dynamically generated Hourly Precipitation Data product will be
available through the Climate Data Online
system. If you have questions/concerns regarding this, please call NCDC Customer Service at (828) 271-4800.
Hourly Precipitation Data (HPD) publication contains hourly
precipitation amounts obtained from recording rain gages located at
National Weather Service, Federal Aviation Administration, and
cooperative observer stations. Published data are displayed in
inches to tenths or inches to hundredths at local standard time. HPD
includes maximum precipitation for nine (9) time periods from 15
minutes to 24 hours, for selected stations. It includes an hourly
account of precipitation amounts for many locations within a chosen
state. This is the final quality controlled copy and generally has a
four to six month time lag. Over 2500 stations are active nationwide.
Storm Data (SD) monthly publications contains a chronological
listing, by states, of storm occurrences and unusual weather

Storm Event database to find various types of storms recorded
in your county or use other selection criteria as desired.
Monthly Climatic Data for the World (MCDW) contains monthly mean
temperature, pressure, precipitation, vapor pressure, and hours of
sunshine for approximately 2,000 surface data collection stations
worldwide and monthly mean upper air temperatures, dew point
depressions, and wind velocities for approximately 500 observing
sites. The publications is issued monthly. This is the final quality
controlled copy and generally has a four to six month time lag.
COOP Data / Record of Climatological Observations Form is a
monthly log that includes a daily account of temperature extremes
(participating locations) & precipitation, along with snow data at
some locations. Available for thousands of sites which are a part of
the cooperative observing network in the US. The forms have a lag
time of 1-2 months.
Data includes a national general summary of
weather conditions, observed extremes of temp & precip by states,
climatological data by station, heating degree/cooling degree
days, flood data and losses, and storm summaries. Upper air data,
sunshine and solar radiation data are also summarized. The annual
issue each year also contains the year's short rainfall duration
statistics, hurricane and typhoon data and storm tracks for various
basins, tornado information and long term statistics.
