Hi @brad1 . Glad you’re asking. Here are direct links to official (from the WF staff) explanations of the CL system:

> CL System for UV calibration explained During early October 2018, we quietly launched our new Continuous Learning (CL) auto-calibration system for UV. The system is designed to evaluate the raw UV sensor data from your SKY, and apply calibration corrections if needed. The data science and back-end techniques involved are fairly sophisticated; here’s a simplified explanation: The UV CL system begins by considering a daily upper threshold UV index based on your precise location, the time of year…

CL for Rain is not yet deployed, but you can gain some insights here: [https://community.tempest.earth/t/rain-gauge-reading-seem-off-auto-calibration-system-not-yet-deployed/930/239](https://community.tempest.earth/t/rain-gauge-reading-seem-off-auto-calibration-system-not-yet-deployed/930/239)
