|

| You'll give me warnings, your data source gives AQI (with

| more about dew point, pressure, and humidity? I mean do most
| people understand these numbers? What percentage actually
| understand humidity?
|
| But seriously, give me the AQI. The official app has 5+M
| downloads and all the weather apps have it. Even Apple has it!
| (actually their weather app is great. Take note). Seriously, why
| is this not here? You would think it would be a common feature
| given all the fires California has and the increasing number
| country wide the last few years. Low hanging fruit here...

| Out west, fireworks started a few wildfires and the air is bad

|
| Edit: Wait, my bad, there isn't an identified link between

|
| These fires were contained, so the bigger wildfires are just

| Zetice wrote:
| It's not really accurate to say we "light stuff on fire"

| Can you explain? Are you saying something about the

| Zetice wrote:
| Yeah, basically. Their main goal is to emit their energy
| via light, not heat, and while if you fire one right into
| a dense, dry forest it won't go well, their standard use
| has their explosion occur in the open air, after which
| the remains are generally pretty cool.
| solardev wrote:
| Don't the "embers" (if that's even the right

| minutes.
| msrenee wrote:
| They stay hot, but not so much fiery generally. You're

| Lighting off artillery shells last night, by the time the
| debris fluttered down, it was cool to the touch. The
| tubes on the ground are a different story though. Shoot,
| the debris from the one the neighbors so kindly dropped
| in the tube upside down when I was 30 feet away didn't
| burn me. Wasn't happy about it, but wasn't even singed.
|
| Were they lighting the fireworks directly on a dry field?
| How far from the tubes were these fires starting?
| solardev wrote:

|
| But it wouldn't be fair to attribute the poor air quality
| today specifically to fireworks unless evidence links them.
|
| The last 4th of July show I watched had designated people on
| the ground stamping out fires as they started. It seemed
| ridiculous to me for the city to still do them in such a dry
| area, but at least each little fire was put out within
| seconds. It was wild seeing the explosions happen, then tiny
| people running around and putting them out, occasionally with
| the help of a firetruck. In the end it worked out pretty well
| and none of the fires spread or lasted past the fireworks
| show. But still kinda unreal to witness...
| rampant_ai wrote:
| A lot of it too is the fireworks themselves. Turns out having

| Rancho Cucamonga is over 300 AQI (hazardous) this morning.
