The Historical Climatology Network (HCN) was established in
part to aid in the detection of regional climate change. 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.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
