Climate

A long-term record of surface weather observations from climate stations are the fundamental data used for characterizing climate. Common measurements include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation.  Not all sites take all measurements.  Temperature and precipitation are collected at most sites.  Online climate station maps provide users with a link to station measurements and information about the measurement history.

The Daily Global Historical Climatology Network (GHCN-D) is an integrated database of daily climate summaries from climate stations. Daily climate records have been integrated and subjected to a common suite of quality assurance reviews by NOAA's National Climate Data Center (NCDC).

The Daily Global Historical Climatology Network of climate stations contains daily measurements of a wide range of meteorological variables. GHCN data has been assessed and controlled for quality and is useful for identifying extremes or evaluating local conditions. More information on GHCN-D is available at http://www.ncdc.noaa.gov/oa/climate/ghcn-daily. There is also a monthly version of GHCN at http://www.ncdc.noaa.gov/ghcnm/v3.php. GHCN-Monthly is a homogenized station database.

The United States Historical Climatology Network (USHCN) represents the most accurate, unbiased monthly historical climate record available. Station data is collected by local volunteers, and jointly maintained by the National Weather Service (NWS) and NOAAA's National Climatic Data Center (NCDC).

The USHCN climate stations represent the most accurate, unbiased monthly historical climate record available in the US covering the past 100 years. This homogenized dataset is useful for assessing long-term trends in a given locale. The USCHN stations were selected based on their spatial coverage, record length, data completeness, and historical stability. More information on USHCN is available at http://www.ncdc.noaa.gov/oa/climate/research/ushcn.
