Applied Climate Information System (ACIS) NRCC NN ¶
ACIS is the abbreviation of Applied Climate Information System, a climate information system developed by the National Weather Service (NOAA). ACIS climate maps are climate charts and maps generated by collecting and organizing global meteorological data and using computer technology and data analysis methods. It can display various climate indicators, such as temperature, precipitation, wind speed, etc., and provide climate change trends and statistical data on different time scales. ACIS climate maps can help meteorologists, climate experts and policymakers conduct climate research and predictions, and develop strategies to adapt to climate change. ACIS climate maps are produced daily using data from the Applied Climate Information System (ACIS) at a spatial resolution of 5 km (0.04 degrees x 0.04 degrees) since 1951 and updated every 1-2 weeks. You can find additional information here and on the Climate Engine Datasets page . Station data in ACIS mainly come from the following networks: Preface – Artificial Intelligence Tutorial
- National Weather Service Cooperative Observer Program (NWS COOP)
- Bureau of Meteorology-Army-Navy/Automated Surface Observing System (WBAN/ASOS)
- Snow Telemetry (SNOTEL)
- Community Collaborative Rain, Hail and Snow (CoCoRaHS) Network
- Remote Automatic Weather Station (RAWS)
NOTE: All near-real-time data is considered preliminary and is subject to change.

terms of use:
- Climate products and tools are developed by regional climate centers to provide users with regular access to the latest weather and climate data. While applied research shows that using such data in decision-making can reduce risk and reduce user costs, it is important to note that near-real-time data is preliminary in nature and sometimes contains errors. Although steps have been taken to eliminate known errors, some data may change after receipt of written records and final quality control steps. Users are therefore forewarned to consider any negative impact that erroneous data may have on their business and to use preliminary data and information at their own risk.
- Regional Climate Centers are not responsible for the misuse or abuse of data provided through our services.
- By using data services through the ACIS website, you automatically agree to the Terms of Use and Disclaimer.
