Ya'll probably know this but I'm very interested in tracking Laura as she landfalls using specifically barometers in phones. I do this with All Clear: https://play.google.com/store/apps/details?id=com.allclearwe... (US android app), source code I write for the clever 'background' sensor data on Android here [1] and animation of the non-landfalling Hurricane Dorian last year as viewed from phones in Eastern Florida [2] I think with Laura landfalling and travelling across the US for a while, there should be a lot of interesting and maybe useful surface-pressure readings to be had. Stay safe if you are anywhere near this hurricane. It is ...unprecedented.

Well, I think the most important metric you can measure on the surface is atmospheric pressure. Simple temperature and humidity is generally insufficient to make good predictions - but pressure at the surface, measured across a geography, can tell you about conditions in the upper atmosphere. I use barometers in phones for this kind of purpose. I think that a minimum of 1 quality reading per 4 sq km would represent sufficiently dense coverage to create an improvement in forecasts. But more is better, since quality can be iffy. Some papers published by Cliff Mass et al from UW might have more info on density work. I'll try to find a link. [1] [2] The work I do is presently just in the US on Android: https://play.google.com/store/apps/details?id=com.allclearwe... with future expansion planned to allow better data acquisition.

Do you mean added resolution of input data, or improved resolution at which the models are run? Input data is frankly very limited - IMO we are barely measuring the atmosphere. Model runs are higher resolutions are only good if there is sufficient input data to seed the models. It's my lifelong passion to increase the usable input data (live atmosphere measurements) that models can assimilate. My latest attempt is to use the barometers in phones to create billions of new 'virtual weather stations'. My US-only Android app (iOS and international coming soon) is https://play.google.com/store/apps/details?id=com.allclearwe... You can see an animation of the data recorded in the Orlando, FL area when Dorian was churning off the coast: https://www.allclearweather.com/hurricane-dorian The data requires significant QA and bias correction to use,
