Historical Climate Network Modernization (HCN-M)
The Historical Climate Network (HCN) was identified in response to the need for the most accurate, unbiased, modern historical climate record available for detecting climate change in the US over the past 100 years or more, The HCN is a sub-network of Cooperative Observer Network (COOP) consisting of 1221 stations. The HCN stations are maintained by the NOAA’s NWS and the HCN data set is maintained by NOAA’s National Climatic Data Center (NCDC).
The HCN-M will sustain the Nation’s regional climate record through modernization of the HCN. Specially, this project will:
- Modernize 1,000 of the existing 1221 HCN stations to collect temperature and precipitation data through automation;
- Provide for expansion capacity to collect other data sets (e.g., National Integrated Drought Information System (NIDIS), dataset); and
- Address gaps in the HCN including: data quality, data availability, and aging technology.
