Applied Climate Information System (ACIS)

The Applied Climate Information System (ACIS) is a climate data management system developed and maintained by the NOAA Regional Climate Centers (RCCs). It is intended to manage the complex flow of information from climate data collectors to the end users of climate information. ACIS brings historical climate information and near real-time data together, pulling from multiple datasets across the Regional Climate Centers (RCCs), to assess historical climate trends, enhance daily operational decisions, and assist with climate-dependent activities.
