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. 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?
Check records of past weather: explore how hot or cold it got through the week, how much rain or snow/sleet/hail fell, and how deep any snow was on the ground. Check what the weather was like on specific dates in history: did a snowstorm affect voter turnout on an election day? What was the weather on dates that are important to you?
2 dni temu · This figure shows how annual average air temperatures have changed in different parts of the United States since the early 20th century (since 1901 for the contiguous 48 states and 1925 for Alaska). The data are shown for climate divisions, as defined by the National Oceanic and Atmospheric Administration.
Check future climate projections for any county in the contiguous United States or borough in Alaska. Generate graphs or maps to compare projections against conditions observed in the recent past. Explore this Dataset
Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting United States.
1 maj 2024 · U.S. Historical Climatology Network (USHCN) data are used to quantify national and regional-scale temperature changes in the contiguous United States (CONUS). The dataset provides adjustments for systematic, non-climatic changes that bias temperature trends of monthly temperature records of long-term COOP stations.
