NOAA NCEI’s Global Historical Climatology Network–Daily, or GHCN-D, dataset provides daily climate records for thousands of observing stations from around the globe, including more than 15,000 stations in the United States. Jared Rennie of CICS-NC is developing an innovative set of tools for accessing and displaying temperature and precipitation data for GHCN-D stations in the United States. You can use the links below to access these tools and explore daily data for the previous year and for the current year-to-date period.
Accessing the Tools
- Temperatures, Year to Date
- Precipitation, Year to Date
- Temperatures, Previous Full Year
- Precipitation, Previous Full Year
Each link will display a color-coded map of stations in the United States. In these analyses, only stations with at least 50 years of data are included, and stations flagged as having a quality control issue are omitted.
Using the Tools
- Temperatures on the maps are shown as departures (in degrees Fahrenheit) from the 1981–2010 average. Precipitation is displayed as a percentage departure from normal using the same base period. For the year-to-date maps, departures are based on the normal average observed as of that date.
- You can hover over an individual station to view the station ID and the current departure from normal value for that station.
- Click on any station to view a detailed plot for the year to date or previous full year.
- The temperature plots show observed daily maximum and minimum temperatures, the 1981–2010 average maximum and minimum temperature range, and the record maximum and minimum range. New records observed in the current year high indicated with colored dates.
- The precipitation plots show accumulated precipitation over the course of the year. Values for the current year are drawn in black, the 1981–2010 average in yellow, the maximum year in blue, and the minimum year in green.
