Data - Daily Data

Daily Reporting Stations. Most daily climate data reports that we receive come from cooperative observer stations, although many 1^st order stations (NWS offices and airports) also provide daily values to this database. The six elements in a standard report include precipitation, maximum temperature, minimum temperature, mean temperature, snowfall and snow cover. Elements derived from the basic observations are also available, in addition to the standard report, which include degree days (heating, cooling, growing), temperature and precipitation extremes, and temperature and precipitation threshold statistics. A subset of these stations report observations in real time, and all stations of this type in our database are updated using NCDC preliminary and final data as it becomes available, usually after about 3 and 6 months, respectively. The real-time data have not undergone the rigorous NCDC quality control process.
