leifdenby··on Ask HN: What are these low quality “code snippet” sites?
Does anyone know of a good list of these copy sites? I just came across this Firefox extension which makes it possible to filter sites from search results: https://addons.mozilla.org/en-US/firefox/addon/hohser/. Would be great with a community blocklist like those for pi.hole
leifdenby··on Show HN: Weather API for non-commercial use
You could store the standard deviation as well as the mean (or median) of the ensemble. That would maximally double your data volume (but would add quite a bit less with compression). The UK Met Office have done same nice work into how to optimally combine the severity and risk of an event into an impact measure

The ECMWF provide meteograms which show the ensemble spread for their global forecasts: https://www.ecmwf.int/en/forecasts/charts/web/classical_mete.... That webpage has a lot is great visualisations
leifdenby··on Climate models are running red hot, and scientists don’t know why
There is a big observational campaign happening right now that is trying to get to the heart of this called EUREC4A (main website: http://eurec4a.eu and information sheet: http://eurec4a.eu/fileadmin/user_upload/eurec4a/2019/Press/E...). The key uncertainty between different climate models is whether shallow clouds in the tropics (which in general cool the Earth through radiation) will disappear or not and make our planet even warmer - some models predict this (!)

We are 100s of individuals from more than 30 national and international partner institutions with planes, drones, ships, ground stations and autonomous buoys trying to understand how and why these clouds form, how that links to their environment, dust from Africa, the ocean current, the jetstream aloft, etc. The positions of the different platforms can be seen live on the main website and the data we are producing is appearing on there too.

If you have any questions about what we're doing I'd be very happy to help or point you towards the right people :)
