Dont waste your time reading that vog prediction map
Ready this instead, was very accurate last nite

hihihi dan d,

YESSS .. discoverd this site about year ago.

Posted it here a while back.

Thanks so much RWR, i sent a link 2 those in charge of the vog prediction model
And told them to use it to update there map but no answer,just asked me what screen
I was looking at. Im still pissed that they wont give real time reporting of the so2
That for sure is been being done down there to the public,Why?

For reference dan d, here's a thread from about a year ago, although this link to Windy is posted by former Punaweb member airportparking:

Hate cross posting like this, but windy is based on forecasted wind values (which have been overestimated by a factor of 2 the actual wind speeds measured over the last few days) and a SO2 model that has a 13mile resolution (can’t predict any differences for locations closer than that) and doesn't account for the Halema'uma'u sized source of SO2 now in Leilani Estates.

While windy, windfinder, and the like have top notch interfaces, they are based on models so off from reality in the Pahoa area as to make them useless. (insert age or gender related put down here as needed

Hi Ironyak,

I've cross referenced www.windy.com with friends around the globe in real time and it works great, down to even localized areas.

These are friends I chat with all the time and we always cross check windy just for fun and to confirm what see of each others locations.

I never looked for the source of the "models" you are speaking of. Would you kindly point those out to me ?

It's pretty clear that the Windy site, as nice as the image looks, is incorrect with respect to SO2 in at least a couple of respects: as ironyak pointed out, it doesn't include the current sources in lower Puna or at the Kilauea summit and isn't of much use to the residents at either location. It also doesn't include the conversion of SO2 to sulfate aerosols (the former is dangerous, the latter is irritating) as the plume moves away from the vents: it forecasts high SO2 in Kona and the Mauna Loa summit (apparently from the upslope winds) where measurements in the past have shown that the downwind vog has converted to sulfate aerosols by the time the plume reaches Kona.

Clearly the Windy site managers can't track every sulfur dioxide source on the planet and I'm not criticizing them on that basis. But the vog modeling site is based on current local information and is a more realistic source of information on sulfur dioxide exposures.

Yep, we never use it for that.

Information about the SO2 model
https://gmao.gsfc.nasa.gov/research/aero...eling/SO2/

While it gives the illusion of fine grained details, windy is low resolution predicted data with no tie to current conditions. Spend a little time comparing the NWS 10 hour predictions for wind and then the actual conditions to see how inaccurate the models are. (the trades have been way overestimated as of late - predicted in this area for last couple days, only now beginning to arrive and weakly)

Wunderground makes it easy:
