The Applied Climate Information System (ACIS) was developed and is maintained by the NOAA Regional Climate Centers (RCCs). It was designed to manage the complex flow of information from climate data collectors to the end users of climate data information. The main purpose of ACIS is to alleviate the burden of climate information management for people who use climate information to make management decisions.

ACIS is a fully functional system with a flexible design and is constantly evolving to incorporate additional data sources, generate new and improved data products, take advantage of emerging technologies, and respond to the needs of its users.
