U.S. Historical Climatology Network (HCN) Temperature and Precipitation, 1880-1994
Listed in NASA Earthdata CMR
The Historical Climatology Network (HCN) was established in part to aid in the detection of regional climate change.
Description
Some of the HCN stations are first-order weather stations, but most are U.S. cooperative stations. To be included in the HCN, a station must have been active in 1987 and have had at least 80 years of temperature and precipitation data.
The HCN database includes station histories, monthly temperatures, and total monthly precipitation data.
