Description

more
Alerts become confirmed when a second satellite pass has also identified the pixel as an alert. Most of the alerts that are not confirmed have not had another satellite pass, due to the 8-day revisit time or cloud cover. These datasets can be downloaded and used in combination with the GLAD Alert data. Values of 3 correspond to "confirmed pixels" and values of 2 correspond to "unconfirmed pixels".
