Why doesn’t today’s satellite observation appear in Tarkka

Before entering the Tarkka service, the satellite observations go through a multi-stage processing chain, which causes a delay between the overpass of the satellite and its appearance in Tarkka. For this reason, Tarkka’s default view displays the true color image of the previous day. For derived material instead of raw observations (e.g., turbidity datasets), observations will be updated with a delay of a few days.

Tarkka is frequently updated, both the user interface and the datasets. Browsers do not always update the latest observations or functionalities automatically. In this case, pressing Ctrl + F5 often helps to force a browser refresh. If this doesn’t help, you may want to try clearing your browser’s history for the last 24 hours.
