@Ondřej-Šutera Thanks. I suspect it's still very hard to get right, the localized summarization and presentation of this complex data. I would hope for Windy to report at least 50th percentile, or preferable 90th percentile AQI averaged over a small region. I'm bothered that Windy happily reports inaccurate data, that seems reasonable on most days, but on days with poor air quality when the numbers matter most, Windy's PM2.5 numbers turn out to be terribly misleading.

I'm concerned that since Wednesday, PurpleAir has reported "PM2.5 AQI" of 200 for the entire inner Bay Area from San Jose to Berkeley to San Francisco, never (when I've checked) breaking below 120 until this afternoon, but in that same period, I have not seen a Windy-reported PM2.5 point sample above 10ug/m^3. Based on Wikipedia's AQI article these numbers are entirely incompatible, both for US AQI scales and Europe's CAQI/EAQI scales. I don't see Windy's PM2.5 reporting for locations in Berkeley, San Francisco, or San Jose correlate with data available on Purple Air. I don't see Windy reporting unhealthy AQI values here at all, when is unhelpful.

Some less testimonial evidence:

• PurpleAir history for a Berkeley sensor:
  
• Current mismatch, showing the consistent, erroneous PM2.5 concentration (50th/90th/95th percentile would be reasonable) reported by Windy for all of the Bay Area.
  

My experience using this, is like hearing: 3.6 roentgen per hour, not great, not terrible; when that is not the state of the world.

I wish the data sources (or lack thereof) were clearer.

Windy has been reporting sub-10 PM2.5 all day, nevermind that it's never that low, however, since this morning, more than 12 hours ago, PurpleAir sensors in SF showed an AQI over 200, and the whole Bay Area has and AQI of at least 150 since morning.

This is frustrating to have such inaccurate data, and no indication of how much the reported data is inferred, ultimately made up, in between reporting sensor.

I find myself using PurpleAir for real time air quality reporting. It would be cool if Windy showed the point sources of measurement.

I would like to see isobars for air quality, to have numeric values on map for better conveying a sense of air quality across a region. I find the color gradient hard to interpret, and can only read one point at a time. Without knowing what the data is grounded in, I'm also unsure at what scale to trust the result.

I would love to see points of measurement, whether EPA.gov's (in the US) reporting points, or Purple Air sensor values.

I'm not the target user, but I wonder whether enabling members to grant demo membership would help convince some more users to join.

I'd be curious to read interviews or case studies with users, to understand who pays for Windy, and what benefits they're deriving. I would also be happy to see or understand that Windy is successfully growing, and hear about status, annually or something.

I want to suggest having layer selection in the URL so I can bookmark it. Premium supports remembering the last layer viewing, but I'm hoping for a more direct way of selecting my desired layer.
