Daily summaries answer questions such as
- What were the high and low temperatures at a station on a specific day?
- How much did it rain last Wednesday?
- How much snow was on the ground on a recent date?
Where do these data come from?
Daily weather records come from automated and human-facilitated observation stations in the Global Historical Climatology Network-Daily database. Data from each station are reviewed regularly for quality and consistency: the data have been checked for obvious inaccuracies, but they have not been adjusted to account for the influences of historical changes in instrumentation or observing practices.
What can I do with these data?
- Find daily records of high and low temperature and precipitation for most localities in the United States.
- Display different variables to look for patterns and compare them among different dates.
- Answer questions such as:
- Where did it rain or snow on a specific date?
- How does temperature change with latitude?
- How much snow was on the ground at a station on a specific date?
-
