I get the impression that the (somewhat) new layered cloud cover doesn’t track as well with observation as the unlayered cloud cover does:
I get it that these are different sources/models, but I notice that, in the layered view, even in the cloudiest of days, the cloud layers never touch each other. Would it be just a matter of scaling? @duane explained something about a bug in the unlayered view here, but I didn’t quite understand it.
For comparison, here’s how Windy shows clouds:
Just to be clear there are no “observations” here. These are all model predictions. So yes, we’re comparing different models which is difficult.
There is a little gap between the cloud layers to provide clear distinction between layers. It also doesn’t look nice when they touch. 100% is when it touches the line above the cloud layer. It’s not a bug.
Ok.
I meant my own.
On second thought… are these comparable? Upon first glance, it seems CMC and ECMWF are forecasting much cloudier days than the others.
yes these are comparing each model
You are comparing total cloud and cloud layers. See:
Some data sources don’t have cloud layers so it falls back to total cloud. The equation used to compute total cloud is different between data source. It is important to understand this equation.
