I switched locations and the issue follows.

Really like the new panels display, great for my new side project in the new year, to map reliability and consistency of the forecast.
This is being addressed and will be rectified soon. It seems there is an anomaly in the BoM data with the highres ACCESS-C APS2 latest update. The Total Cloud Cover layer is missing the High Level Cloud Cover layer. For the time being the work around is to check ACCESS-R for the same time period until Robert creates a new derived cloud field and documents it accordingly. The issue is already in the raw data from the BoM and we don't modify any raw data.

The High Cloud Cover layer on its own is correct.
ACCESS-C vs. ACCESS-R High Cloud Cover (%)

The Total Cloud Cover layer is incorrect as it contains only middle and low clouds.

You can overlay the High Cloud Cover onto the Total Cloud Cover with the gold padlock to get the right cloud coverage in the mean time.

We will post when the new cloud field is updated.
