Climate Data Online CDO - The National Climatic Data Center. Annual Climatological Summary contains historical monthly and annual summaries for over 8000 U. Climate Data Online CDO provides free access to NCDC's archive of global historical weather and climate data in addition to station history information. These data include quality controlled daily, monthly, seasonal, and yearly measurements of temperature, precipitation, wind, and degree days as well as radar data and 30-year Climate Normals.
Climate Data Online Observing stations are located in the United States of America, U. Virgin Islands, Puerto Rico, and Pacific islands of the U. Annual Climatological Summary is derived from the NCDC Summary of the Month dataset (DSI-3220). It includes temperature average max, min, and extremes, departures from normal, degree day, and frost/freeze values plus precipitation averages and extremes including snowfall data. The National Climatic Data Center NCDC is the world's largest active archive of weather data. NCDC produces numerous climate publications and responds to data requests from all over the world.
Climate Data Online CDO - National Climatic Data Center The major parameters are: monthly mean maximum, mean minimum and mean temperatures; monthly total precipitation and snowfall; departure from normal of the mean temperature and total precipitation; monthly heating and cooling degree days; number of days that temperatures and precipitation are above or below certain thresholds; and extreme daily temperature and precipitation amounts. station data (from COOP and ASOS stations) was developed to meet the needs of climate analysis studies that require data at monthly and annual time resolutions.
