Using MODIS data (NDVI and FIRMS), the dataset detected forest clearing, with a minimum threshold of 25% pixel clearing. Alerts, indicating the percentage of clearing (`alert_delta`) and timestamp (`alert_date`), were provided. WRI stopped updating FORMA alerts because other tools were more often used.
