Desktop: None of my favorties are posted on the map
-
I still have all my favorties, can search for them and get the location for forecast, but there used to be a marker 'heart shaped' at each location. These are gone. Heave been for over a day now. Refreshed until blue in face. Firefox, Debian Linux. Addidional question: why is tehre no Rain Radar in Calabria for months now (maps shows 'no data' text all over the overlay)? Is Mte Pettinascura out of business? How come services like weatheronline have data?

@idefix37 My options on-map has another form, and the favorites are no longer there. I see most of the ingredients,but ... it looks very different.
-
@idefix37 Oh and ... I tried to read 'this post' about the weather radar in Italy, but had no permission to view the page.
-
@idefix37 Ah! Found it. Now I knew what had happened to it, could dig it up. Thanks!

@BertBril
Have you checked this ?
Concerning radar in Italy, see this post
Well, Rome may be good now, South Italy hasn't been 'up' for at least a month now, maybe more. OTOH servies like weatheronline have been continuously providing data, so I can't see it being Mte Pettinascura being 'down'. Here's what I see:

@BertBril
Some apps don't display actual radar data, but radar-like precipitation, derived from model / satellite-computed data.Windy chooses to display actual radar data. If the radars fail, Windy is forced to display "No Data."
-
@idefix37 I understand completely. I just would like to know what causes Windy's sources to be cut off of the data streams, while other services seem to have uninterrupted data. It begs the question: what is the normal source of radar data for Windy for our area? Is it Mt Pettinascura? Looking at the 'circles' of data, and the lack of precision exactly where Pettinascura is not high enough to 'view' the surface, it must be. What happened? Did Mt Pettinascura close down lately? Does anyone have any idea? I cannot find anything about it on Google.
More CO2 is better (for nature, for the planet, for us). Its effect on the climate is negligeable, and what if it weren't? Nature would still love that! So stop making propaganda for Big Capital.

See this topic. The Italian meteorological agency's radar does not currently cover this area.

@BertBril The radar data on Windy come from official radar sources only. In Italy, the provider is the Protezione Civile (Civil Protection Department) and the Aeronautica Militare (Air Force), which operate and maintain the national radar network.
At the moment, the Civil Protection is performing maintenance on several radar systems across Italy as part of the PNRR modernization program. Because of this, multiple radars, including Mt. Pettinascura, are temporarily offline, resulting in gaps or missing radar coverage.
Information about this maintenance were published on the Protezione Civile website, at the bottom of their radar page below the embedded radar map. Here: https://mappe.protezionecivile.gov.it/it/mappe-e-dashboard-rischi/piattaforma-radar/I assume that some other weather websites may appear to have continuous "radar" coverage in those areas because they don't actually use real radar data. Instead, they likely rely on satellite imagery and colorize dense cloud areas to make them look like radar returns. I’ve looked at different websites and often noticed varying data patterns between them, while Windy has consistently shown more accurate data.
Unfortunately, Windy cannot restore these data until the affected radars are back online.

@David-Polášek I think our area is covered, it always was. @YacineBoussoufa hits the spot here. His post expains everything.
-
@YacineBoussoufa Thanks, that explains everything.
I'm curious why you or the Windy guys (not sure if you're one of them) are not using the same procuderes everywhere in mountaneous terrain. The weather radar is very inaccurate around here because we are at 600 m altitude, and Mt Pettinascura peeks over a mountain halfway and misses a column of about 600 meter at our location. In the valleys it's even worse. Looking from above will solve a lot of problems. This is why I usually consult weatheronline, not Windy, when it comes to planning walks with the dogs.
I guess 'there are no plans in that direction' ...?

Hey @BertBril
showing the reality, even if it's not positive, is our main focus.
If the radar is off, it's off. If you want to see rain from the models, just switch the models ("Rain, thunder" layer).David Polášek

@David-Polášek I understand what you're saying, but I think you didn't get what I'm saying. The rain radar is not a very good tool in mountaneous areas. The rain radar, even though usually positioned on a peak, can 'see' the ground level rarely. In my case, even while I live on a crest, it still misses a column of about 600 meters. This means it is pretty bad in many cases.
Looking from above this problem would be ... well ... different. But I bet it's going to give a better view of what is coming towards me.

@BertBril
Windy doesn't install radars. If the position of the radar doesn't allow you to see behind an obstacle, what can Windy do?
You say “Looking from above will solve a lot of problems”.
How do you do that? The organization that owns the radar provides the radar data which shows where the existing radar is recording echoes. That's all.
In mountains there are blind areas. The solution is to build new radars for a better coverage of the area. -
@idefix37 The solution may be to not use the radars in areas where these are not present (currently all of South Italy) or simply untrustworthy.
I am not an expert on thsis matter, but this is what Lumo says:
Q: "Is there an alterntive to a dedicated rain radar by using satellite data - for areas that have no rain radar coverage?"
A: "Short answer: Yes – you can estimate precipitation from satellites, and in many parts of the world those satellite‑derived products are the primary source of near‑real‑time rain information when ground‑based radars are absent. The trade‑off is that satellite estimates are less precise, coarser, and have a larger latency than a dedicated weather‑radar network, but modern multi‑sensor algorithms (microwave, infrared, passive‑microwave, and blended gauge‑radar‑satellite products) can still give you useful quantitative rainfall fields."
More CO2 is better (for nature, for the planet, for us). Its effect on the climate is negligeable, and what if it weren't? Nature would still love that! So stop making propaganda for Big Capital.

@BertBril
OK, but it would be difficult to mix data from real radars with those from satellites giving these radar-like images. -
@BertBril Lumo gives a lot of info on how to implement it. Not sure how to pass it to you, but it includes a table like screenshot
.
There's also stuff on combining with existing radar, and really much more. I'm sure if you ask your own AI targeted questions, it will come up with much more specific stuff ...
